When you set up Facebook Audience campaigns using Marketing APIs, you might run into specific errors. Below are some common errors and how to resolve them.

​
Resolve the business_management permission error

If the Facebook Audience sync fails because your access token is missing the business_management permission, generate a new token that includes this permission using the Graph API Explorer, and then extend it to a long-lived token.
  1. Open the Graph API Explorer.
  2. From the Meta App drop-down, select your app.
  3. From the Permissions drop-down, make sure ads_read, ads_management, and business_management are all selected. business_management is the permission commonly missing that causes this error.
  4. Click Generate Access Token. Graph API Explorer with the business_management permission selected and the Generate Access Token button
  5. The generated token is short-lived. To extend it, open the Access Token Debugger.
  6. Paste the token, and then click Extend Access Token to generate a long-lived token that is valid for 60 days. Access Token Debugger showing a short-lived token and the Extend Access Token button
  7. Copy the extended token, and then use it to connect Facebook Audience in MoEngage.

Check for Required Permissions

Facebook’s API does not let you create or change Custom Audiences if the terms have not been accepted. If the contract is not signed, Facebook triggers an error when you try to create or edit a Custom Audience.

  2. Select the Network tab.
