Core Workflows

1. Discover Managed Pages

List all Facebook Pages you manage to get page IDs and access tokens for subsequent operations.

Tool: FACEBOOK_LIST_MANAGED_PAGES

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | fields | string | No | Comma-separated fields (default: id,name,access_token,category,tasks,about,link,picture) | | limit | integer | No | Max pages per request (default: 25) | | user_id | string | No | User ID (default: me) |

Always run this first to cache page_id values. Avoid repeating discovery calls -- cache the results.

Known Pitfalls

| Pitfall | Details | |---------|---------| | Scheduling too close to now | FACEBOOK_CREATE_POST with scheduled_publish_time less than ~10 minutes in the future returns HTTP 400 -- enforce a larger buffer for bulk runs | | Unix UTC timestamps required | scheduled_publish_time must be Unix UTC -- timezone conversion mistakes cause off-by-hours sched
