{"error_type": "OAuthException", "code": 400, "error_message": "Invalid redirect_uri"}

Question

Firstly, this is my Instagram URL after the login:

https://www.instagram.com/oauth/authorize?client_id=$MYCLİENTİD&redirect_uri=https://localhost:4000/İnstagram/Insta.php/&response_type=code&scope=user_profile,user_media

And this is the error that page shows me:

{"error_type": "OAuthException", "code": 400, "error_message": "Invalid redirect_uri"}

When I try to get user token from Instagram, I get that error.
I've tried to change the redirect_uri=(Valid OAuth Redirect URIs), but the error is the same as before.

Answer 1

I could not find this documented anywhere, but through trial and error, I found that the redirect_uri had to:

1. Use https
2. Be publicly accessible (e.g. localhost and specifying a port number won't work)
3. Not include parameters (I found they were getting stripped out, which would cause a redirect_uri mismatch when I later requested an access token)

Answer 2

I had the same problem and I solved it as following:
I first went here: (remember to change your instagram app id in the below URL) https://developers.facebook.com/apps/your_instagram_app_id/instagram-basic-display/basic-display/

Then I set my Client OAuth Settings, Deauthorize and Data Deletion Requests as "https://localhost:3000/".

That worked for me.
