To enable the 3Chat Agent to securely call open interfaces (OpenAPI) of your enterprise’s external systems, we recommend configuring a permanent access token in the “Tool Invocation” feature. This token authorizes 3Chat to establish a trusted connection with your business systems. You can create the required authentication credentials in advance, making it easier to connect to multiple interfaces on the same platform without recreating them each time.
Feature Navigation
3Chat Agent → MCP → Access Authorization
Configuration Steps:
-
Log in to the 3Chat backend and navigate to the “Access Authorization” page using the top menu.
-
In the top-right corner of the page list, click the New action.
-
On the details page, fill in the authorization title, description, and token information. The token prefix is currently fixed as “Bearer”.
-
After entering the above information, click Save to complete the creation of the access authorization.
Best Practices
- For the authorization title, use the format “Authorizer” + “Purpose”.
- For the authorization description, provide detailed information about the purpose, usage method, and validity period of the authorization.
- Grant only the minimum necessary permissions to a single token in the external system to ensure data security.
- Rotate tokens regularly (if supported by the system).
