Facebook Pages publishing via the Meta Graph API. Connecting Facebook is the entry point for both facebook and instagram platforms in letmepost — see the Instagram page for the fan-out.

​
Connect

POST /v1/accounts/connect/facebook. Standard Facebook Login for Business OAuth. After complete, we discover Pages via GET /me/accounts and create one platform_accounts row per Page (plus one IG row per Page that has an IG Business linked).

​
Scopes

pages_show_list             — list Pages the user manages
pages_manage_posts          — create posts on Pages
pages_read_engagement       — pre-req for posts on some apps
business_management         — Pages connected via Business
instagram_basic             — read IG Business per Page
instagram_content_publish   — IG container publish
The IG scopes are requested even on the Facebook connect because the same OAuth grant covers both. extended adds insights / engagement scopes.

​
Token lifecycle

Long-lived (~60-day) tokens, refreshed on schedule.
