Link a catalog to a WhatsApp number

Connects a Meta Commerce catalog (owned by the same business portfolio as the WhatsApp Business Account) to the number's WABA. The WhatsApp connection's own token cannot do this, so pass catalogAccountId naming a facebook, instagram or metaads account whose Meta login carries catalog_management.

Get a number's commerce settings

Whether the linked catalog is shown on the business profile (`isCatalogVisible`) and whether customers can build a cart (`isCartEnabled`).

List the catalogs linked to a WhatsApp number

The Meta Commerce catalogs connected to the number's WhatsApp Business Account. Pass `catalogAccountId`: the WhatsApp connection's own (embedded signup) token answers an empty list even when a catalog is linked, only a Meta login with catalog_management sees the link. A linked catalog is what product, product_list and catalog_message interactive messages sell from (see POST /v1/inbox/conversations/{conversationId}/messages) and what customers browse in the WhatsApp app. Create and fill catalogs with the /v1/ads/catalogs endpoints.

WhatsApp account ID
