Overview
This node, named "PhoAi Ultimate Facebook Post," is designed to interact with Facebook Pages via the Facebook Graph API. It primarily supports operations related to posting content on Facebook Pages and managing access tokens for those pages.
The specific operation "Phở Ai lấy AccessToken" (which translates roughly as "Pho Ai get AccessToken") retrieves an access token for a selected Facebook Page. This token is essential for authenticating subsequent API requests to post content or upload media on behalf of that page.
Common scenarios where this node is beneficial include:
- Automating Facebook Page posts by programmatically obtaining access tokens.
- Integrating Facebook Page management into workflows without manual token handling.
- Uploading media files or posting messages to Facebook Pages using the retrieved access token.
Practical example:
- A marketing automation workflow that periodically posts promotional content to multiple Facebook Pages by first retrieving valid access tokens and then publishing posts or uploading images/videos.

Output
The node outputs JSON data structured as follows:
For the "Phở Ai lấy AccessToken" operation:
success: Boolean indicating if the operation succeeded.response: The response object containing the access token and related page information returned from the external service endpoint/get_access_token_by_page_id.
For other posting or uploading operations (though not requested here), the output includes success status, API responses, and details about attached media.
No binary data output is indicated for this operation.
Dependencies
- Requires an API key credential for authentication with the external service endpoint at a base URL (referenced as
cin code, e.g.,https://.../get_access_token_by_page_id). - Uses HTTP requests to communicate with the external API and Facebook Graph API.
- Uses the
form-datalibrary for multipart form uploads when posting media (not directly relevant for the AccessToken operation). - Requires proper configuration of the API credential within n8n to authorize requests.
Troubleshooting
Common issues:
- Invalid or expired API credentials may cause authentication failures.
- Incorrect Facebook Page ID input can lead to errors fetching the access token.
- Network or timeout errors when calling the external API or Facebook Graph API.
Error messages:
- Errors thrown include descriptive messages such as "Upload failed" or "No binary data found" (for media uploads).
- Status codes and error details from the API response are included in error descriptions to aid debugging.
Resolutions:
- Verify that the API key credential is correctly set up and has necessary permissions.
- Ensure the Facebook Page ID is correct and accessible by the authenticated user.
- Check network connectivity and retry if transient errors occur.
