API Integration Failures With CommPeak

Issue

Third-party applications cannot connect or interact with CommPeak's API.

Possible causes and solutions

The issues you can experience when using CommPeak's API to connect 3rd party software can have the following reasons:

Reason 1. Incorrect API credentials

Verify that the API keys and API tokens are correctly entered and have not expired.

📘
NOTE
Check the corresponding sections in Managing Portal API Keys for more details.

Reason 2. API Endpoint changes

Ensure that your application is pointing to the correct and current API endpoints. Since October 2026, most CommPeak APIs are served from https://api.commpeak.com. To update an older integration, see Migrating to the New API Reference.

Reason 3. Permission issues

Confirm that your API key has the access it needs. To call the Dialer API, Lookup API, or other services, the key needs Full access (all services). To create, change, or delete data through the Portal API, Read-only (Portal API only) must be off. For TextPeak, also check the role permissions in your TextPeak account.
