Connect WhatsApp Business
Exchanges the authorization code Embedded Signup returned and connects exactly the selected phone number as one whatsapp_sender. Send the WABA id and phone-number id emitted by the same popup attempt; both are treated as selectors and verified against Meta before use. A selected number that matches a non-retired, same-project voip_line is linked to it; a number absent from Photon inventory stays unbound; a matching non-retired cosmos_line, foreign VoIP line or unassigned VoIP line fails the operation before registration. Connecting is free — no plan requirement — but Billing must report the project’s organization as ready with a payment method on file. The Idempotency-Key is required and permanent: replaying the same key returns the original operation forever. Requires the platforms:write permission bound to the project resource in the path.
Authorizations
Account Service Key, prefixed with pho_ask_, sent as Authorization: Bearer <key>. Acts on behalf of its owning account, subject to the permissions and credential restrictions of each operation. Account access tokens and OAuth grants also use the Bearer header. In organizations that require SSO, Account Service Keys are not accepted for managing the organization's SSO settings, deleting the organization, or checking whether it can be deleted.
