I need the flow of new Facebook leads to land automatically inside my CRM and stay in sync without manual exporting or copying. Both my Facebook Business Manager and ad account are already active; what is missing is the technical bridge: • Build or configure a Facebook App, enable OAuth 2.0 and obtain the correct permissions so the integration remains long-lived and compliant with Meta’s policies. • Connect that app to my CRM. • Map every lead field coming from my lead-gen ads to the corresponding fields in the CRM, test with Facebook’s lead-generation tool, and confirm real-time delivery. • Provide a quick rundown on how to refresh tokens, add new ad forms later, and troubleshoot common permission errors. Acceptance criteria A test lead created in Facebook Lead Ads appears in my CRM within seconds.
