Create custom OAuth 2.0 credentials for API integrations
Custom credentials let you securely store OAuth 2.0 authentication details in JustCall. Once saved, these credentials can be reused across workflows and custom integrations without exposing client secrets.
Available on: All JustCall plans
When to use this
Use OAuth 2.0 Client Credentials when:
- The external API supports the OAuth 2.0 Client Credentials grant type.
- No user login or consent screen is needed.
- Authentication relies on a
client_idandclient_secret.
Common scenarios include server-to-server integrations with CRMs, internal tools, and analytics platforms.
Create a credential
- Go to Integrations in JustCall.
- Click the All Integrations tab and search for Server Configuration.
- Click +Integrate to open the New Custom Credential window.
- Fill in the fields:
| Field | Description | Example |
|---|---|---|
| Authentication Type | Select the auth method | OAuth 2.0 |
| Credential Name | A friendly label for reference | "Salesforce Production" |
| Token URL | OAuth token endpoint from the external service | https://api.example.com/oauth/token |
| Client ID | Identifier provided by the API provider | From your API dashboard |
| Client Secret | Secret key paired with the Client ID | Keep this secure |
| Grant Type | How access tokens are requested | Client Credentials |
| Scope (optional) | Permissions to request, space-separated | read write offline_access |
The right side of the modal shows a Request Preview of how JustCall will request an access token.
Test the connection
- Click Test Connection in the top right of the modal.
- JustCall attempts to fetch an access token using the details you entered.
- Check the Response tab for a valid access token or success message.
If the test fails, verify your Token URL, Client ID, and Client Secret with your API provider.
Save and use
Click Save in the bottom right corner. The credential is stored securely and available for selection in custom integrations and workflows.
