The Meta and WhatsApp integration is the delivery layer of Galantis. Where the Shopify integration provides the data — customer profiles, orders, products, consent — the Meta integration is what turns that data into actual WhatsApp messages reaching customers’ phones. Galantis communicates with Meta through the WhatsApp Cloud API (Meta Graph API v23.0), using your WhatsApp Business Account access token to send messages, submit templates, upload media, and push catalog data. Inbound messages and status updates from Meta arrive via webhooks registered to your WABA.

​
What the Meta integration provides

  • Outbound messaging — campaigns, automation messages, and Inbox agent replies sent via the Message API
  • Template management — template creation, submission, and approval status sync via the Template API
  • Media upload — images, videos, and documents uploaded for use in template headers via the Media Upload API
  • Catalog sync — product data pushed from Galantis to Meta via the Catalog API
  • Inbound messages — customer messages received through your WhatsApp number arrive via webhook and appear in the Inbox
  • Message status updates — delivered, read, and failed status callbacks for every sent message, used for analytics and automation condition evaluation

​
Authentication model

Galantis stores one Meta access token per connected WhatsApp Business Account, encrypted per tenant. The token is obtained via Meta OAuth during the WABA connection flow and used for all subsequent Meta API calls. Access tokens can expire or be revoked if permissions change in Meta Business Manager. When this happens, all Meta API calls from Galantis fail for that workspace. Symptoms include messages not sending, catalog sync failing across all products simultaneously, and template status no longer updating. See Connecting WABA for how to reconnect and refresh the access token.
