Test API Access

Implementing a complete OAuth authorization flow can take time, especially during the early stages of development. To help you get started quickly, ZoomInfo allows you to generate an access token directly from the APP Creation Portal after creating your application.

While the Authorization Code Flow and Client Credentials Flow are recommended for production integrations, the Generate Access Token option provides a quick way to obtain an access token for API exploration, development, and testing.

This allows you to begin making API requests without first implementing the full authorization flow, helping you validate your integration before investing in production-ready authentication.

Generate Access Token for Testing

1. Open App Creation Portal

Choose the option that applies to you:

• Enterprise customers: Sign in to the ZoomInfo Developer Portal to view your applications.
• GTM.ai self-serve customers: Sign in to GTM.ai, go to the Developer tab to view your applications.

If you haven't created an application yet, follow the App Creation guide before continuing. After creating your application, return to the portal to view and manage all applications associated with your account.

2. Generate a Bearer Token

Find the application you want to test and select Generate under the Bearer Token column

A new browser window will open and prompt you to sign in again. ZoomInfo application sessions and API authorization sessions are managed separately, so re-authentication is required. After successful authentication, the window will display Success and close automatically.

3. Copy the Access Token

After authentication completes, a popup displays your newly generated access token.
Copy the token using either the Copy button or manual selection from the text field.

4. Start Calling ZoomInfo APIs

Now that the token is copied to your clipboard, you can paste that token into the ZoomInfo API Reference and begin trying out the ZoomInfo APIs!
