I'm working on a Python script that uploads videos directly to a Facebook Page as Reels using the Facebook Graph API. My videos are hosted on a CDN, and I would like to upload them directly to Facebook without downloading them to my local server.

I am currently using Facebook's video_reels endpoint to upload videos as reels. For local files, the process works perfectly by uploading the video in binary form. However, I want to avoid downloading the video locally when it's hosted on a CDN and instead directly upload it from the CDN URL.

Here’s a simplified version of my current code:

import requests # Facebook API parameters page_access_token = 'your_page_access_token' page_id = 'your_page_id' api_version = 'v20.0' video_url = 'https://cdn.example.com/video.mp4'  # CDN URL of the video video_description = "My awesome reel" video_title = "Reel Title" thumbnail_path = 'thumb.jpg' # Step 1: Initialize the upload session for reels def initialize_upload_reel():     url = f"https://graph.facebook.com/{api_version}/{page_id}/video_reels"     payload = {         'upload_phase': 'start',         'access_token': page_access_token     }          response = requests.post(url, data=payload)     if response.status_code == 200:         data = response.json()         video_id = data['video_id']         print(f"Upload session started. Video ID: {video_id}")         return video_id     else:         raise Exception(f"Error initializing reel upload: {response.text}") # Step 2: Upload the reel video file def process_upload_reel(video_id, file_size):     url = f"https://rupload.facebook.com/video-upload/v20.0/{video_id}"     headers = {         'Authorization': f'OAuth {page_access_token}',         'Content-Type': 'application/octet-stream',         'offset': '0',         'file_size': str(file_size)     }     with open(video_url, 'rb') as file_data:         response = requests.post(url, headers=headers, data=file_data)          if response.status_code == 200:         print("Reel Uploaded")     else:         raise Exception(f"Error uploading reel video: {response.text}") def publish_reel(video_id, description, publish_time=None, published=True):     url = f"https://graph.facebook.com/{api_version}/{page_id}/video_reels"     thumb_file = {'thumb': open(thumbnail_url, 'rb')}          payload = {         'access_token': page_access_token,         'video_id': video_id,         'upload_phase': 'finish',         'title': title_entry.get(),  # Ensure title is passed         'description': description_entry.get()  # Ensure description is passed     }     if publish_time:         payload['video_state'] = 'SCHEDULED'         payload['scheduled_publish_time'] = publish_time     else:         payload['video_state'] = 'PUBLISHED' if published else 'DRAFT'     response = requests.post(url, data=payload, files=thumb_file)     thumb_file['thumb'].close()     if response.status_code == 200:         check_video_status(video_id)              else:         raise Exception(f"Error publishing reel: {response.text}") 

The Problem: When I attempt to upload using the CDN URL, I receive the following error message:

{   "error": {     "message": "There was a problem uploading your video file. Please try again with another file.",     "type": "OAuthException",     "code": 6000,     "error_subcode": 1363130,     "error_user_title": "Video Upload Is Missing",     "error_user_msg": "The video was not uploaded.",     "fbtrace_id": "Ai3SicB2QxOVA-ZpIQu7cjT"   } } 

It seems like Facebook's Reels API doesn't support uploading videos directly from a CDN URL using the file_url parameter, or I may be missing something in the implementation.

Question: Is it possible to upload videos directly from a CDN URL to Facebook Reels via the Graph API without downloading the video locally first?

If yes, how should I structure my API request to achieve this?

If no, what is the recommended approach for handling CDN-hosted videos in this scenario (such as avoiding downloading the video to the server)? Any help or guidance would be greatly appreciated!

I'm tring to get tagged user in post. Currently I'm fetching user post using Business Discovery and some of the post data is possible to fetch. But for tagged user no information is post.

Is there way or endpoint that I'm just overlooking? or just simply not possible with Business Discovery?

Also if it not possible with Business Discovery I would like to know if there is any other way to do it.

I am working on an app that helps in publishing the post on different platforms in a single go. User has to write about their post and add pictures if they want and then select the social media they want to post on like they can select facebook and instagram or facebook,Instagram and X and when the click the button based on the selection post should be publish on there social media account.

What Problem I am facing?

I am able to create a button that helps user to login to facebook and thats working perfectly. But when it comes to publishing a post it doesn't work. Please let me know what I can do to make that code run??

Here is the code snippet for publishing post to facebook.

private void postToFacebook(String token, String msg) {         String url = "https://graph.facebook.com/v17.0/me/feed";         StringRequest stringRequest = new StringRequest(Request.Method.POST, url,                 new Response.Listener<String>() {                     @Override                     public void onResponse(String response) {                         // Handle success                         Log.d("FBResponse", response);                         Toast.makeText(MainActivity.this, "Post Successful!", Toast.LENGTH_SHORT).show();                     }                 }, new Response.ErrorListener() {             @Override             public void onErrorResponse(VolleyError error) {                 // Handle error                 Log.e("FBError", error.toString());                 Toast.makeText(MainActivity.this, "Failed to Post: " + error.getMessage(), Toast.LENGTH_LONG).show();             }         }) {             @Override             protected Map<String, String> getParams() {                 Map<String, String> params = new HashMap<>();                 params.put("message", msg);                 params.put("access_token", token);                 return params;             }         };         RequestQueue queue = Volley.newRequestQueue(this);         queue.add(stringRequest);     } 

This is the error I am getting when I am trying to publish a post.
