When you’re looking to connect your HubSpot account with other tools or build custom integrations, getting your hands on an API key, or more accurately, an access token, is usually step one. Now, if you’ve been around the block, you might remember the good old “HubSpot API key” that used to live in your settings. But here’s the thing: HubSpot retired that legacy API key on November 30, 2022, and you couldn’t even create new ones after July 15, 2022.
So, if you’re trying to generate an API key in HubSpot today, you’re actually looking to create what HubSpot calls a Private App. Think of a Private App as your new, super-secure API key. It gives you a special access token that acts like a key, letting your custom tools talk to your HubSpot data, but with a lot more control and security. This is a must because it means you can give your integrations exactly the permissions they need, and nothing more, which is a huge win for protecting your data. Whether you’re integrating a custom form, automating data entry, or connecting with an internal system, understanding Private Apps is essential for anyone wanting to truly leverage HubSpot’s powerful API ecosystem.
The Evolution of HubSpot API Access: From Legacy Keys to Private Apps
For years, HubSpot users and developers relied on a single, global API key to authenticate their applications and custom integrations. This was pretty straightforward: you’d generate an API key, plug it into your code, and voilà, your app could talk to HubSpot.
What Was the Old HubSpot API Key?
The old HubSpot API key, often referred to as the hapikey parameter in API requests, was a unique string of characters. It was specific to your HubSpot account and, at the time, was one of the easiest ways to get your custom applications talking to HubSpot’s APIs. You could use it for all sorts of things, like creating custom functionality or making webhook calls.

Why Did HubSpot Make the Change?
While convenient, that old API key had a pretty big drawback: it granted root access to almost all your HubSpot data and API endpoints. Imagine giving someone the master key to your entire house just so they could water your plants. That’s essentially what the legacy API key did. If that key ever fell into the wrong hands, it meant complete, unfettered access to sensitive customer data, deal information, and more. This was a significant security risk.
HubSpot, always working to boost cybersecurity and protect customer data, recognized this vulnerability. So, as part of their ongoing efforts, they decided to phase out the API key. The official sunset date was November 30, 2022, and they stopped allowing new API keys to be created after July 15, 2022. This move was to encourage everyone to shift to more secure authentication methods, like Private Apps and OAuth, which offer better security and more granular control.
Meet Private Apps Your New API Key
This is where Private Apps come into play. In simple terms, a Private App is HubSpot’s modern, more secure answer for internal integrations and single-account access. Instead of a single, all-powerful API key, when you create a Private App, you get an access token. This token does the same job as the old API key – it authenticates your application to use the HubSpot APIs – but with a crucial difference: granular permissions, also known as scopes. Smarter Choices for Your Business: The Best HubSpot Alternatives
With a Private App, you can explicitly define what data and what actions your integration is allowed to perform. For example, if your app only needs to read contact information, you grant it only read permissions for contacts. This means if that access token were ever compromised, the damage would be limited only to what you explicitly allowed. It’s like giving someone a key only to the garden shed, not the entire house. This targeted access significantly reduces security risks and gives you much better control over your data.
When to Use OAuth
While Private Apps are perfect for tools built specifically for your HubSpot account, there’s another powerful authentication method called OAuth. You’ll typically use OAuth if you’re building an application that needs to be installed across multiple HubSpot accounts, like a public app you want to list on the HubSpot App Marketplace, or an integration that other businesses will use. OAuth is even more robust in terms of security and user experience, allowing users to grant access without sharing their login credentials. Over 70% of developers recommend utilizing OAuth for API authorization due to its robust access management capabilities.
However, for most custom, internal integrations where you just need to “generate an API key” for your own portal, a Private App is the way to go.
Step-by-Step: Generating Your HubSpot Private App Access Token The “API Key”
Ready to get your new “API key” aka Private App access token? Let’s walk through the process. It’s pretty straightforward, and once you do it once, you’ll see why it’s so much better than the old system. Mastering HubSpot’s AI: Your Ultimate Guide to Smarter Business Growth
Prerequisites
Before you start, make sure you have:
- An active HubSpot account.
- Administrative access in that HubSpot account. Specifically, you need the necessary configuration permissions to create and manage Private Apps. Usually, a Super Admin role will cover this.
Step 1: Log In and Navigate to Private Apps
First things first, log into your HubSpot account. Once you’re in, look for the settings icon it usually looks like a gear in the main navigation bar at the top right of your screen. Click it to open your settings.
On the left sidebar menu, you’ll see a list of options. Scroll down and click on Integrations, then select Private Apps.
Step 2: Create a New Private App
You should now see a page listing any existing Private Apps you might have. To create a new one, simply click the “Create a private app” button.
Step 3: Basic Info for Your App
Now it’s time to give your app a little personality! On the “Basic Info” tab, you’ll need to configure some details: Mastering the HubSpot API with Python: Your Ultimate Guide
- Name: Give your app a descriptive name. This helps you identify what the app does later. For instance, “Website Form Submissions” or “CRM Data Sync Tool.”
- Description Optional but Recommended: Explain what this app is for. This is super helpful, especially if other team members might interact with it or if you revisit it months down the line.
- Logo Optional: You can upload a square image as a logo for your app.
Step 4: Define Scopes Permissions
This is arguably the most important step for security and functionality. The “Scopes” tab is where you tell HubSpot exactly what data and actions your app needs access to. Remember, the goal is to grant the principle of “least privilege” – give it only what it needs to do its job, and nothing more.
You’ll see a list of available permissions, often divided into categories like CMS, CRM, Settings, and Standard.
- How to Add Scopes: Click “Add new scope”. A panel will appear where you can select specific checkboxes for the permissions your private app needs. You can also use the search bar to find specific scopes.
- Be Specific: If your app only needs to read contacts, select
crm.objects.contacts.read. If it also needs to create contacts, addcrm.objects.contacts.write. Don’t just select everything! This granular control is what makes Private Apps so much more secure than the old API keys. - Review Requirements: If you’re building an integration for a specific HubSpot API endpoint, check the HubSpot API documentation for that endpoint. It will list the exact scopes required.
Once you’ve carefully selected all the necessary scopes, make sure to review them one last time.
Step 5: Review & Create
After you’ve set up the basic information and, most importantly, configured the scopes, take a moment to review everything. Happy with your choices? Great! Click the “Create app” button, usually located in the top-right corner.
Step 6: Get Your Access Token
Once your Private App is created, you’ll land on its details page. This is where you’ll find your shiny new “API key” – which is actually your Access Token. Master HubSpot API Search: Your Ultimate Guide to Finding CRM Data
- Look for the “Auth” tab or the “Details” tab.
- Under the “Access token” section, you’ll see an option to “Show token”. Click it to reveal your token.
- Copy this token immediately! It’s a long string of characters. This is the value you’ll use in your API requests. Keep it safe and secure, just like you would any password. HubSpot even allows you to rotate this token if it ever gets compromised, creating a new one and expiring the old one instantly.
And that’s it! You’ve successfully generated your HubSpot Private App access token, which is the modern and secure equivalent of generating an API key in HubSpot.
Using Your New HubSpot Access Token in API Calls
Now that you have your Private App’s access token, let’s talk about how to actually use it to make those HubSpot API calls. This is where the magic happens and your custom tools start talking to your HubSpot data.
The Authentication Method
Unlike the old hapikey that was often included as a query parameter in the URL, Private App access tokens are used in the HTTP Authorization header of your requests. This is a standard and more secure way of authenticating API calls. Why Blend HubSpot Data with Power BI?
Here’s what it generally looks like:
Authorization: Bearer YOUR_ACCESS_TOKEN_HERE
You'll replace `YOUR_ACCESS_TOKEN_HERE` with the actual token you copied from your Private App.
# Examples of API Calls
Let’s say you want to fetch some contact data or submit a form. Here’s a general idea of how you'd structure a request.
Using `curl` a common command-line tool:
```bash
curl --request GET \
--url "https://api.hubapi.com/crm/v3/objects/contacts" \
--header "Authorization: Bearer YOUR_ACCESS_TOKEN" \
--header "Content-Type: application/json"
This example would fetch a list of contacts from your HubSpot CRM.
Using a Client Library e.g., Python:
HubSpot offers client libraries for various programming languages like Python, Node.js, PHP, Ruby. These libraries make it even easier to interact with the API. You typically initialize the client with your access token.
```python
import hubspot
from hubspot.crm.v3.objects import BasicApi
# Replace with your actual access token
access_token = "YOUR_ACCESS_TOKEN"
client = hubspot.Client.createaccess_token=access_token
try:
# Example: Get all contacts
api_response = client.crm.contacts.basic_api.get_pagelimit=10
printapi_response.results
except ApiException as e:
print"Exception when calling BasicApi->get_page: %s\n" % e
Using Tools like Postman:
Postman is a popular tool for testing APIs.
1. In Postman, create a new request.
2. Set the request method GET, POST, etc. and the API endpoint URL e.g., `https://api.hubapi.com/crm/v3/objects/contacts`.
3. Go to the Authorization tab.
4. Select "Bearer Token" from the Type dropdown.
5. Paste your Private App access token into the "Token" field.
6. Send your request!
HubSpot Form API Example:
If you’re working with form submissions, the process for using your access token would be similar. You’d use a POST request to the relevant forms API endpoint, including your access token in the `Authorization: Bearer` header. HubSpot's API documentation has specific examples for different endpoints, including forms.
No matter which method you use, always make sure your access token is included correctly in the `Authorization: Bearer` header. If it's missing or incorrect, you'll likely run into authentication errors.
Best Practices for Secure API Integration
Using HubSpot's API to integrate with other tools is incredibly powerful, but with great power comes great responsibility, especially when it comes to security. Here are some best practices to keep your integrations safe and sound:
# Security First: Protect Your Access Tokens
Your Private App access token is effectively the key to your HubSpot data. Treat it with the utmost care.
* Never Hardcode Tokens: This is a big no-no. Don't embed your access token directly into your application's source code. If your code repository is ever exposed, your token goes with it.
* Use Environment Variables or Secret Management: The best practice is to store your access tokens in environment variables or a dedicated secret management service like AWS Secrets Manager, Azure Key Vault, or HubSpot's own Secrets Management feature. This keeps your sensitive information separate from your code. When your application runs, it retrieves the token from these secure locations. This means if you ever rotate your key, you only need to update the value in one secure place, not throughout your code.
# Principle of Least Privilege: Just What's Needed
We talked about this when setting up scopes, but it bears repeating. When defining the scopes for your Private App, always stick to the absolute minimum permissions required for your integration to function. If your app only needs to read contact emails, don't give it permission to delete deals. This significantly limits the potential damage if your token is ever compromised.
# Token Rotation: Keep Things Fresh
Even with all the security measures, it's a good habit to rotate your Private App access tokens periodically. While Private App tokens don't automatically expire like OAuth tokens might, rotating them every few months say, every six months is a solid security practice. If a token is compromised, you can rotate it immediately in your HubSpot account, which instantly invalidates the old one and generates a new one.
# Understand API Rate Limits
HubSpot, like most API providers, implements rate limits to ensure fair usage and maintain system stability. If your application makes too many requests too quickly, HubSpot will temporarily block your requests.
* What are they? HubSpot uses a "sliding window" approach for rate limiting, meaning requests are evaluated on a rolling basis, not fixed intervals. You'll see headers in API responses like `X-HubSpot-RateLimit-Max` maximum allowed requests and `X-HubSpot-RateLimit-Remaining` how many you have left.
* Limits Vary: Rate limits depend on your HubSpot subscription level. For example, Professional accounts might have a daily limit of 650,000 requests per day and a burst limit of 190 requests per 10 seconds, while Enterprise accounts can go up to 1 million requests per day. You can even purchase API Limit Increase capacity packs for higher tiers.
* Strategies to Avoid Hitting Limits:
* Implement Exponential Backoff: If you hit a rate limit error, don't just keep trying. Wait progressively longer periods before retrying your request.
* Caching: Store data you frequently access instead of making repeated API calls for the same information.
* Batch Requests: If you need to perform similar operations on multiple records, see if there's a batch API endpoint available. This lets you send many operations in a single request, reducing your overall call count.
* Optimize Data Fetching: Only request the data you truly need.
# Monitoring and Logging
Keep an eye on your API usage and activity.
* HubSpot Logs: Your Private App in HubSpot has a "Logs" tab where you can review the API calls made by your application, including the method, response, and time period. There's also a "Security" tab to track when access tokens have been viewed or rotated. This is super helpful for debugging or investigating suspicious activity.
* Application-Level Logging: Implement logging within your own application to track API requests and responses. This makes troubleshooting much easier.
By following these best practices, you can build robust, secure, and efficient integrations that leverage HubSpot's API without putting your valuable data at risk.
Troubleshooting Common Issues
Even with the best planning, sometimes things don't go as smoothly as you'd hope. Here are a few common issues you might run into when working with HubSpot's API using a Private App access token, and how to troubleshoot them.
# 401 Unauthorized
This is probably the most common error you'll see.
* What it means: A 401 Unauthorized error typically means that your API request couldn't be authenticated. HubSpot doesn't recognize your credentials.
* How to fix:
* Check your Access Token: Double-check that you've copied and pasted the entire access token correctly. Even a single missing character will cause this error.
* Verify `Authorization: Bearer` Header: Make sure your request includes the `Authorization` header, and that it's formatted exactly as `Bearer YOUR_ACCESS_TOKEN`. No typos, no extra spaces.
* Is it the Right Token? Confirm you're using the access token from the *correct* Private App that's linked to the HubSpot account you're trying to access.
# 403 Forbidden
If you're getting a 403 Forbidden error, HubSpot recognizes who you are your token is valid, but you don't have permission to perform that specific action or access that particular data.
* What it means: Your access token lacks the necessary scopes permissions for the API endpoint you're trying to hit.
* Review Your Private App Scopes: Go back to your Private App's settings in HubSpot, navigate to the "Scopes" tab, and verify that all the required permissions are selected. For example, if you're trying to update contacts but only have `crm.objects.contacts.read` selected, you'll get a 403. You'd need to add `crm.objects.contacts.write`.
* Check API Documentation: Always consult the HubSpot API documentation for the specific endpoint you're using. It will clearly list the required scopes.
# Rate Limit Errors
If your application starts getting errors after a flurry of requests, especially with messages about "Too Many Requests," you've likely hit a rate limit.
* What it means: You've exceeded the number of API calls allowed within a certain time frame either the burst limit or daily limit.
* Implement Backoff/Retry Logic: As mentioned in best practices, design your application to wait and retry requests with increasing delays if it encounters rate limit errors.
* Reduce Request Frequency: If possible, space out your API calls.
* Batch Requests: Use batch endpoints where available to consolidate multiple operations into fewer API calls.
* Check HubSpot Plan: If you're consistently hitting limits, review your HubSpot subscription tier. Higher tiers offer more generous API limits, and you can also purchase additional capacity packs.
* Monitor Usage: Use the "Logs" tab in your Private App settings to see your API call history and identify patterns that might be causing you to hit limits.
By understanding these common issues and their solutions, you can efficiently debug your HubSpot API integrations and keep everything running smoothly.
Frequently Asked Questions
# What happened to the old HubSpot API key?
The old HubSpot API key the `hapikey` parameter was officially deprecated by HubSpot. As of November 30, 2022, it is no longer supported for authenticating API calls. You also couldn't create new API keys after July 15, 2022. This change was made to enhance security and provide more granular control over API access.
# What is a HubSpot Private App?
A HubSpot Private App is the modern, secure way to connect your custom tools and internal integrations to a single HubSpot account. Instead of an all-encompassing API key, it generates a specific access token that grants access only to the data and actions you explicitly define through "scopes." This provides much better security and control.
# How do I find my API key Access Token for a Private App?
Once you've created a Private App in your HubSpot account Settings > Integrations > Private Apps, you can find its access token on the app's details page. Look for the "Auth" or "Details" tab, and then click "Show token" under the Access token section. Remember to copy it and keep it secure!
# Can I still use the `hapikey` parameter?
No, the `hapikey` parameter for authentication is no longer supported as of November 30, 2022. Any integrations still using it will fail. You must migrate to using Private App access tokens or OAuth for public apps in the `Authorization: Bearer` header.
# What are scopes in a Private App?
Scopes are specific permissions you grant to your Private App. They define what data your app can read, write, or modify within your HubSpot account. For example, `crm.objects.contacts.read` allows your app to read contact data, while `crm.objects.contacts.write` allows it to create or update contacts. By carefully selecting scopes, you ensure your app only has the access it needs, improving security.
# Is there a cost to use the HubSpot API?
Access to HubSpot's core APIs is generally included with your HubSpot subscription. However, API call limits rate limits vary depending on your HubSpot product and tier e.g., Starter, Professional, Enterprise. If your usage exceeds the standard limits, particularly for Professional and Enterprise accounts, HubSpot offers API Limit Increase capacity packs that you can purchase to get higher daily and burst request allowances.
# How often should I rotate my Private App access token?
While Private App access tokens don't expire automatically like some other tokens, it's a good security practice to rotate them periodically. Many experts suggest rotating your tokens every six months, or immediately if you suspect the token has been compromised. You can easily do this from the Private App settings in HubSpot.
