META Invalid Conversions API Credentials

Hi everyone,

I’m having some trouble connecting my ManyChat account to my Facebook Ad Account and Conversion API, and I’m not sure what I’m doing wrong.

Here’s the situation:

1. Account X is the Admin and Owner of:

   • The Facebook Page connected to ManyChat.
   • The Ad Account I’m trying to connect.
   • The Business Manager where the Conversion API token was generated.
      

2. My ManyChat account is linked to the same Facebook Page that’s managed by Account X.

I’ve tried connecting:

• Through Facebook, and
• Using the dataset and token option with the Conversion API.

No matter which method I use, the connection just doesn’t work, and I can’t figure out why. I get the “Invalid Conversions API credentials”

What I’ve Checked So Far:

• Account X has full Admin access to everything (Page, Ad Account, and Business Manager).
• The Conversion API token was generated in the same Business Manager as the Page and Ad Account.
• The Page and Ad Account are properly connected in Meta Business Suite.

What I Need Help With:

1. Why isn’t the connection working if everything is owned and managed by Account X?
2. Are there any extra steps I should take or common issues I might have missed when setting this up?
   
   
   I want to track when a user clicks on a button in a flow in messenger from a ad in the messenger 
   
   Thanks.
