Why Postproxy for Facebook?

Skip Facebook Graph API complexity

Facebook rate limits are managed automatically with intelligent retry logic.

Support all formats

Publish feed posts and Stories through one unified API.

How Facebook Publishing Works with Postproxy

Facebook's Graph API supports publishing to Pages (not personal profiles). Each Page has its own access token and permission set. Postproxy manages Page token handling and routes your content to the correct Graph API endpoint based on the format you specify.

Common gotchas Postproxy handles for you

Postproxy abstracts inconsistencies, handles API versioning, and manages the chunked upload flow for videos.

First comments and multi-page management

Postproxy lets you set first_comment in your request and handles the post-then-comment flow atomically, managing tokens across all connected Pages.
