End-to-end recipes: n8n, MCP, webhooks, pairing, and OAuth2 for third-party apps.
n8n
Install the community node, create the credential, build a first workflow, and understand the single-webhook caveat before you add a trigger.
MCP
Connect Claude, Cursor or any MCP client to the remote WASync server. Six tools, no code on your side.
Webhooks
One signed endpoint per account. Signature verification, the event catalog, the retry policy and secret rotation.
Pairing code & QR
The QR rotates every 20 seconds. Ship both paths, because a one-device onboarding cannot photograph its own screen.
Bring a number from another provider
Move a WhatsApp Business API number from another provider to WASync with the in-app wizard and keep your reputation with Meta.
HTTP request step in Chat Flows
Ask an external system over HTTPS from a flow and use the answer in the next steps. Made from a Cloudflare Worker, never from WASync's servers.
Leads from WhatsApp chats
Who gets the lead for a new number, what happens when the number is already in your CRM, and the re-contact window that keeps a customer who writes back after a lost lead on the same record.
Smart Processes (SPA)
The WASync tab in the item card, conversations linked to items, and robots and Chat Flows on SPA automation rules.
WhatsApp templates (WABA)
Create templates, follow Meta's approval, and send them from the CRM chat, Bitrix24 automation rules and Chat Flows.
OAuth2 for third-party apps
Only for apps that other WASync customers install. Authorization Code with PKCE, rotating refresh tokens, and one structural limit.
