I’m looking to wire up my Facebook Lead Ads with my self-hosted Odoo 19 CRM through n8n (Claude helpers are fine if you prefer them for parsing or enrichment). Every new lead on Facebook must appear in Odoo instantly, not in hourly or daily batches. Scope • Listen for Facebook Leads webhooks, handle the access-token refresh cycle automatically, and push data into Odoo’s CRM endpoints the moment a form is submitted. • Map and upsert Contact Information, current Lead Status, and all custom fields we capture on the form; nothing should be dropped. • Avoid duplicates by checking existing records in Odoo before insert. • Build the flow entirely in n8n, export it as a JSON bundle, and include a concise README explaining environment variables, Facebook App settings, and the Odoo REST endpoints you touched. • Implement basic error handling so failed calls are re-queued or logged with enough context for me to troubleshoot. Acceptance criteria – I import your n8n workflow, add my credentials, trigger a test Facebook form, and see the lead appear in Odoo 19 with every mapped field filled correctly. – No manual refresh is required; sync fires in real time and continues to do so after token expiry. – README lets a mid-level admin reproduce the setup from scratch. If you’ve connected Facebook Leads to Odoo before—or have strong n8n experience—this should be straightforward. Let me know your approach and the rough timeline, and we can get started right away.
