D2C brands increasingly close sales in the DMs. A customer asks "is this back in stock?" under an Instagram post, sends a Messenger question about sizing, and buys within the hour. But those conversations live in the Meta Business Suite inbox, completely disconnected from ERPNext. Reps tab back and forth between apps, promising leads never become Lead or CRM Deal records, response times slip, and there is zero reporting on which social conversations actually convert to revenue. ERPNext core has strong CRM and helpdesk primitives, but it ships with no Instagram or Messenger connector. The Meta Graph API integration, webhook handling, token lifecycle, and a two-way conversation UI simply do not exist out of the box, and most generic "social" marketplace apps are broadcast schedulers rather than inbox tools wired into your CRM.

ECOSIRE builds a proper Frappe app for this: its own module with a clean hooks.py, versioned DocTypes, and permission wiring, that connects to the Meta Graph API (Instagram Messaging plus the Messenger Platform) and mirrors every inbound and outbound message into ERPNext. A Social Conversation DocType groups messages by contact and channel; a child Social Message table stores each turn with direction, timestamp, and Meta message id for idempotency; and a Social Account DocType holds the connected Facebook Page / Instagram Professional account plus its encrypted long-lived access token. Inbound events arrive at a whitelisted webhook endpoint (@frappe.whitelist(allow_guest=True)) that verifies the X-Hub-Signature-256 HMAC before enqueuing work to a background job, so bursts of DMs never block the request.

On top of that data model we build the workflow you actually want. A hooks.py doc_events handler on inbound messages runs lead-capture logic: match the sender against an existing Contact, or create a new Lead with the social handle, first message, and source channel, then link the Social Conversation to that Lead, CRM Deal, or Helpdesk HD Ticket. Agents reply from inside ERPNext through a custom desk page or Frappe UI form; the reply is posted back to Meta via a server-side whitelisted method and stored as an outbound Social Message. A comment-to-message automation watches for comments on your posts and ads and triggers a private-reply DM using Meta's comment API, so a public "how much?" becomes a private sales thread without manual work. Scheduler events refresh long-lived tokens before expiry, retry failed sends, and reconcile any webhook the platform dropped.

Because this is built to order, nothing is a black box. We start with a scoping call to confirm your channels, CRM routing rules, role profiles, and whether conversations should land as Leads, Deals, or Tickets. We build against Frappe/ERPNext v15 or v16 to match your site, run UAT on a staging bench, then install on production behind your own Meta app and tokens. Typical delivery is one working week from confirmed scope. You receive the full source in a git repository, so you own the code and can extend or self-host it independently of ECOSIRE.
