A session is one WhatsApp link under your account. You create and drive it with the external API at https://backend-dev.wabsync.com/api/v1.

​
Typical flow

  1. POST /sessions/create with session_name
  2. GET /sessions/{sessionId}/get-qr-code while status is pairing-related
  3. Poll GET /sessions/{sessionId} until status is ready
  4. Send messages and receive inbound traffic (see Webhooks)
List sessions: GET /sessions (pagination via page / per_page).

​
Status values

These are the status values returned on session resources (and in OpenAPI): Operational tip: treat ready as the gate for outbound messaging and for inbound webhook delivery. Until then, keep polling or watch the dashboard.

​
How status moves while pairing

As the provider connects the phone, status commonly moves through values such as created → scan_qr_code → ready (exact path can include other values from the table). Failed starts end in failed.
