https://developers.facebook.com/docs/marketing-api/audiences/guides/engagement-custom-audiences I have taken the instagram_business_account id from me/accounts?fields=name,id,access_token,instagram_business_account{id} and use it inside event_sources id.No luck for me.Please help me.Thanks in advance

Finally i fix it.i was given instagram_business_account_id instead of instagram profile ID anybody who is facing the issue, if your instagram account is attached to a facebook page Instagram business profile ID can be found from here

https://developers.facebook.com/docs/graph-api/reference/page/instagram_accounts/

example

{fb-page-id}/instagram_accounts?fields=id and access token used is fb page access token .Cheers,Happy coding!!
