Issue Summary: I am attempting to set up the Conversions API (CAPI) for my Instagram automation, but the connection is failing despite my automation templates appearing correctly in Meta Ads Manager.
The Problem:
-
Manual Setup: Entering the CAPI token manually in ManyChat results in an "Invalid Credentials" error.
-
Meta Events Manager: In the Dataset settings, the option to "Connect Instagram as a Messaging Data Source" is greyed out.
-
Multiple Datasets: I noticed ManyChat has auto-created new datasets (e.g., "Event Data"), which seem to be conflicting with my original dataset.
Troubleshooting Done:
-
Confirmed "Full Control" permissions for my profile on all assets.
-
Verified the IG account is a Business profile with "Allow access to messages" enabled.
-
Regenerated tokens and checked for trailing spaces.
-
Identity is confirmed as the ManyChat template shows up in my Engagement ads.
Question: How can I resolve the "Invalid" error to link my existing data, and why is the messaging data source greyed out in the Meta backend?
