Issue: Getting 'Unsupported post request' error when accessing /accounts with WABA_ID despite having all required permissions:

• whatsapp_business_messaging
• whatsapp_business_management
• Tech Provider verification
• Full business verification

Error: 'Unsupported post request. Object with ID '[WABA_ID]' does not exist, cannot be loaded due to missing permissions.'

Tried:

• New phone numbers
• Fresh access tokens
• Different WABA_IDs
• Permission resets

Note: Can successfully send messages via API, but contacts API access fails. Request format appears correct, but permissions seem blocked despite having all verifications.

Meta support directs all technical issues to their Developer Forum, but the forum throws a ReactComponent error, making it inaccessible. Left without official support channels to resolve this.

I created an app on Facebook and added Facebook Login use case. Now I need to add user_link permissions. From what I understood to this end I need to add another use case but when I click Edit use cases I see only Run ads to promote your app use case. What should I change to be able to add user_link permission?

I created an app which uss facebook API for post and read content from facebook pages. App was recently approved, I can go live. Everything worked in test regime with test accounts, but when I started testing it live with real accounts I have en errors I cannot explain.

1. I removed permission role as admin/tester from my fake test account, to test it as external. I can login with it and get page data. I can post on behalf of this user. But for some reason I cannot get feed. I receive an error, that I miss pages_read_engagement permission, but in my business app stated, that this permission is granted and active. And when I login, this permission is on the list, that I grant app with this data. I wrote already letter to facebook direct support, but didn't receive any reply yet. Any ideas?

2. When I try to login with my personal facebook account, I can, I get user data, but I cannot get any pages data. Array with pages is returned empty. I do have pages_show_list permission. In this case there is no error calling this api, but why I cannot see any pages?

I will appreciate any advice

I am trying to retrieve the from field for comments on a post using the Facebook Graph API. The from field is showing correctly for page authors but not for regular users who comment on the post.

I have ensured that I have the required permissions, including:

email pages_show_list pages_read_engagement pages_read_user_content pages_manage_posts

The API request I am making is as follows:

**GET /{page_post_id}/comments** 

As per the Facebook Graph API documentation, this should return the from field for all comments. However, the from field is missing for users and is only available for page authors. i am also using user access and page access token as docs suggest but still the issue persist.

1. Verified that I have all the required permissions.
2. Checked the API request to ensure it was correctly formatted according to the documentation.
3. Tried testing the request with different page posts and still encountered the same issue.
4. Use Facebook graph API Explorer to test different permissions and endpoints. but there is also from field missing.

I have been researching several Stack Overflow articles but i did not point any potential solution, and it seems that many people are experiencing the same issue in the Facebook community. It would be very helpful if someone could provide me with the latest information. I need to know whether this is an issue with V20 or if I am missing something.

I expected the from field to return the information for both users and page authors, but it's only appearing for page authors.

I have a Facebook app running in production, and I've created a system user within Facebook Business Manager. After generating a system user access token, I have also generated a user access token for the system user. However, the API response only returns the page ID and not the page access token. What steps should I take to ensure that the system user has the necessary permissions, and how can I retrieve the page access token successfully?

I generated a system user access token and used it to call the Facebook Graph API to retrieve the page access token. I expected the API to return the page access token, but instead, it only returned the page ID. I was expecting the access_token field in the response but did not receive it.

Here is the CURL used to fetch the page access token :

curl -X GET "https://graph.facebook.com/v19.0/{page_id}?fields=access_token&access_token={user_access_token_or_system_user_access_token}"
