Instagram Graph API - Pages list returns empty (/me/accounts)

Question

I am trying to set up an Instagram Graph API integration.

The problem in short: when trying to query the GET /me/accounts endpoint, i get an empty data list (pages list). And that makes me unable to continue with data fetching (beacuse I need his instagram user id).

Details:

• My instagram app is not live yet, still in development (yet to go through app review process)
• Im trying to do it with an access token of a friend (for my account it works). I think I completed all the prerequisites for that to be possible: added his developer account as a developer in my app, he connected the instagram account to the facebook page, i got the access token with the following permissions: instagram_basic,pages_show_list,pages_read_engagement,instagram_manage_insights
• The same flow works for my account
• The same result received when using the Graph API Explorer
• Im basically trying to set up with those two guides (tried both ways, still empty list): https://developers.facebook.com/docs/instagram-api/getting-started and https://developers.facebook.com/docs/instagram/business-login-for-instagram

Answer 1

Solved: All I had to do was add the 'business_management' permission
