What "Facebook API developer" actually covers
Facebook's surface splits into separate systems with their own permissions and review paths — the Graph API for Pages and Messenger, the Marketing API for ads, and the Conversions API for server-side measurement. The work is picking the right ones, getting them approved, and wiring them into something your team can actually run.
Page publishing & management
Scheduled posts, replies and page-level changes managed through the Pages API, driven from your CMS or internal tool instead of the native composer.
Messenger Platform bots
Persistent menus, quick replies and keyword-triggered flows, with a clean handoff to a human agent logged for anything the bot shouldn't handle.
Marketing API & ad automation
Campaign creation, budget and bid changes, and performance reporting pulled programmatically instead of clicked through Ads Manager by hand.
Conversions API (CAPI)
Purchase, lead and other events sent server-side and deduplicated against the pixel, so ad measurement holds up under ATT and cookie loss.
Lead Ads sync
New submissions pushed straight into your CRM within seconds via webhook, with field mapping and de-duplication handled on the way in.
OAuth & App Review
Business Login flows, long-lived token refresh, and the demo recordings Meta requires for every permission submitted for review.
// built for
Who this is usually for
Multi-account tooling
One dashboard managing pages, ad accounts and reporting across several clients, with permissions kept separate.
CAPI-backed catalogs
Server-side purchase events and product catalogs that keep ad measurement accurate as browser tracking keeps shrinking.
Facebook Login as a feature
Letting your own users connect a Page or ad account and manage it without leaving your product.
Messenger & page moderation
Auto-routing inbound messages and comments to the right queue, with escalation to a human when needed.

How the build runs
Discovery & permission mapping
Confirm which Page, ad account, and system-user access exists today, then map exactly which permissions the integration needs — no more, no less.
App Review submission
Build the app, record the required demo videos, and submit for Meta's App Review so publishing, messaging or ads permissions actually go live.
Integration build
Publishing, Messenger, ads or CAPI logic built against your existing stack, with Business Use Case-aware request queuing from day one.
Testing against live traffic
Real webhook events, token expiry, and edge cases like revoked permissions or paused ad accounts tested before go-live.
Launch & monitoring
Deployed with logging and alerts on failed calls, expiring tokens, or rising BUC usage, so issues surface before your client notices.

Questions that come up early
What permissions are needed, and how does App Review work?
It depends on the integration: publishing needs pages_manage_posts, Messenger needs pages_messaging, ads automation needs ads_management. Anything beyond basic Page info requires Meta to review the app, including a screen-recorded demo of each permission in use, handled as part of the build.
Does this include Meta Ads and Marketing API integration?
Yes. Campaign creation, budget and bid changes, and performance reporting can be built against the Marketing API so they run programmatically instead of through Ads Manager's UI, with the same access-tier requirements and app review Meta applies to ad automation.
What is the Conversions API, and why does it matter now?
It sends purchase, lead, and other events to Meta directly from the server, deduplicated against the browser pixel. Since iOS App Tracking Transparency and browser cookie restrictions cut into pixel-only data, server-side events are what keeps ad measurement and optimization accurate.
Can Lead Ads be synced automatically to a CRM?
Yes, through a Lead Ads webhook. A new submission triggers a push straight into the CRM within seconds, instead of someone exporting a CSV from Ads Manager. Field mapping and de-duplication against existing contacts are handled as part of the sync.
How are rate limits and webhook reliability handled?
Facebook throttles by a rolling Business Use Case score rather than a flat call count, so integrations track that score and back off before hitting it, with caching to cut unnecessary calls. Webhooks are signature-verified, treated as at-least-once delivery, and reconciled against the Graph API so nothing is silently missed.
Have a Facebook integration to build?
Send over what it needs to do — publishing, Messenger, ads, or CAPI — and get a scoped plan back with the permissions it'll actually require.
