I'm developing an app that will make use of the Business On Behalf Of API (https://developers.facebook.com/docs/marketing-api/business-manager/guides/on-behalf-of#bm-client). Based on the steps in the documentation above, I was able to progress with regards to login (step 0), creation of the partnership between the BMs (step 1), generation of the access token for the client's BM system user (step 2) and I am stuck in obtaining the system user identification number (step 3) through the following request:

curl -i -X GET
"https://graph.facebook.com/v19.0/me?access_token=<CLIENT_BM_SU_ACCESS_TOKEN>"

I have a valid system user token, with all desired permissions and attributes, validated through the Access Token Debugger (https://developers.facebook.com/tools/debug/accesstoken/?access_token=...&version=v19. 0). However, the request to get this user's id continues to return an empty json as a response.

Request made: curl --location 'https://graph.facebook.com/v19.0/me?fields=id&access_token=...'.

The response is always {} (empty json).

access token debugger output

My app's permissions at login are: pages_read_engagement business_management ads_management

The system user access token created in the customer's BM has the following permissions: ads_management pages_read_engagement

as the documentation suggests (I've already tested generating this token with other permissions, but the problem persists).

I tried to research whether it was a lack of permissions, but I couldn't find anything conclusive. I researched the app's settings and didn't get promising results either. I tested using both Login and Login for Business as a Product for my app, but there was no difference in relation to the problem. Making this same request with user or system user tokens, administrators or not, from my accounts and my BM works as expected (returns the user id), but when it is a system user of the client's BM, following the step the step of the Business Intermediation documentation, it doesn't work.

I need this id to assign the assets to this user and then have access to the client's pages. By manually obtaining the user ID through the debugger and following the other steps, it is possible to complete the entire process and carry out the intermediation as expected (manage the assets on behalf of another company). However, this step is not allowing me to automate the process 100% and will hinder the usability of my application. Am I missing something?

There are several that are similar, none of them relate to this specific problem. I am trying to get FB pages owned by a user. Before this i was getting issue that business pages were not listing so i found that i need to add business_management permission and the permission fixed the issue. But now i am still not getting some user's (previously connected and also sometimes new users) pages and not able to connect with my app. What can be the reason as i have also tried remove app from business integration setting.

But... when I visit the page on the web, I am an admin. I have full access to all the admin functions. It also appears in my list of pages in the Pages Manager app on Android.

I have read the documentation for the hint as to what I am doing wrong, and nothing found helpful.

i have tried it with another app (similar to my requirement) and the page is listing. I'm not able to find what i am missing in my request (may be any permission).

i am trying to upload a reel (MP4, 16 seconds, and 9 MB) using facebook graph API, but i get the following error:

Failed to upload reel: {'error': {'message': 'The video file you tried to upload is too small.

Any idea :(?

i test like facebook post request in graph facebook api. i use my access token and i have a post_id, this endpoint is:"http://graph.facebook.com/{post_id}/likes". when i send this request then post have a post_id was liked. I did the same thing on postman (endpoint:https://graph.facebook.com/v19.0/{post_id}/likes) and passed in the parameter Authorization:{access_token} but it failed and returned 400 bad request: "error": { "message": "(#3) Publishing likes through the API is only available for page access tokens", "type": "OAuthException", "code": 3, "fbtrace_id": "AU3wMLbb67rRXR4mgF-4FoX" }

I hope that there is someone who has been like me and has solved this problem to share with me the documents to solve it.

some of the users are getting the error Facebook Login is currently unavailable for this app, since we are updating additional details for this app but there aren't any issues or required actions on the developer account Error

Some users try to use facebook login through my app but they get the exception that the feature is unavailable
