I'm trying to grant access to business assets to another user's business account. I'm following this documentation : https://developers.facebook.com/docs/marketing-api/business-asset-management/guides/business-to-business#b2b-grant
I'm using the API Graph Explorer to test the requests. I'm using a test facebook App.
To give access to the fb page, I'm using this request :
endpoint : page-id/agencies type : POST body : JSON : { "business": "business_account_id", "permitted_tasks": "MANAGE" } and the token I'm using is the page token.
The result is : { "success": true }
But when I do the same with the ad account, I get : "error": { "message": "(#3) Application does not have the capability to make this API call.", "type": "OAuthException", "code": 3,
The request is :
endpoint : act_adAccount-id/agencies type : POST body : { "business": "business_account_id", "permitted_tasks": "ANALYZE" }
and the token is the token generated when the user logged in to my app with these permissions : email pages_show_list ads_management ads_read business_management public_profile
Could anyone help please ? Thanks
