Branded Calling

Create a caller identity share link

Creates a single-use link (valid 7 days) where the end business fills in the caller identity itself, with no Zernio login: display name, logo, call reasons, the authorizer and the three references. What it submits lands under your team as requested, the same review as an API submission, and branded_calling.identity.status_updated fires. Scope the link with identityId (complete an identity that is requested or changes_requested), with enterpriseId (a new identity for a registered business), or with neither (the business registers itself and its first identity). The person opening the link can forward a fresh one to someone else, which retires theirs.

Resend the authorizer's code

Emails the authorizer a fresh 6-digit code (the previous one stops working). Only while the identity is `pending_email_verification`.

List all calls (unified history)

Unified call history across ALL of your numbers: both channels (WhatsApp Business Calling + regular phone/PSTN), inbound and outbound, newest first. Unlike `GET /v1/voice/calls` (PSTN-only) and `GET /v1/whatsapp/calls` (one account at a time), this endpoint needs no `accountId` and never requires fanning out one request per number. Any row can be opened channel-agnostically via `GET /v1/calls/{id}` and `GET /v1/calls/{id}/recording`; no branching on `channel` needed. When the counterparty number matches a CRM contact, `contactId` and `contactName` are set. Cursor pagination: pass the returned `nextCursor` as `before` to fetch the next page. `nextCursor` is null on the last page.

enterpriseId?string

A registered business the identity belongs to.

identityId?string

An identity in review to complete. Not with enterpriseId.
