Set up Intercom Messenger
Open Settings → Apps & developers → Analytics & tracking → Intercom for the target project. Review the enablement switch and the account value expected by the implementation.
Copy the Messenger app ID
For the Messenger setup that uses an app ID, obtain the app_id from the intended Intercom workspace. Enter the value in the corresponding field, select the desired enablement and save. Open the intended storefront with a test account and check the Messenger and its destination workspace.
Distinguish the app ID from an API token
The app ID identifies the Messenger workspace. A Developer Hub access token authorizes separate API access. Confirm the expected credential with the project owner before using any token, and keep it in the approved secret manager.
