My question: When I try to make a POST request to the Instagram Basic Display API, I get this error message.
{
"error_type": "OAuthException",
"code": 400,
"error_message": "Missing required field client_id"
}
Any ideas on what I’m doing wrong? Here’s the tutorial I’m trying to follow.
Thanks so much for your help!
Can you share a screenshot of the information you are trying to submit in your POST?
Hi I used the doc steps and have my test user and token generated.
But I’m still facing this error message and it get me crazy. Can somebody tell me what I’m doing wrong pls ?
export const authToInstagram = functions.https.onRequest((req, res)=>{
return cookieParser()(req, res, ()=>{

the oauth2.getToken({

keep saying it missing client-id… but I can clearly see it in my request. Some people say that the data should be sent through the body req but I don’t understand how to do it.
I had a similar issue and found that double-checking the app settings in the Facebook Developer portal fixed it—the client ID was set to the wrong platform. Also, if you’re testing stuff like growth or engagement separately, I’ve used https://famoid.com/buy-instagram-followers/ and it made it easier to test different features on accounts with more activity.
