How can I get the Facebook page id which is connected to the instagram business account? Is there an Instagram API that is available for it? I have already searched through the Instagram developer documentation.
You cannot get Facebook Page ID from Instagram ID.
However, you can get the Instagram ID if you have the Facebook Page ID
GET graph.facebook.com
/{FB_PAGE_ID}?fields=instagram_business_account
and then:
GET graph.facebook.com
/{IG_BUSINESS_ID}?fields=id,ig_id,username
ig_id
is the instagram_id
, id
is instagram_business_id
