List conversations. GET /api/ext/v3/conversations. Returns conversations, newest first. Filter by channel_type and/or channel_id. Results can be limited by the active channel scope; do not assume all connected channels are included. The returned id can be used as the target of other conversation APIs. The whatsapp filter excludes WhatsApp group conversations; use whatsapp_group to filter those conversation records.

Permissions

For API access tokens and OIDC tokens, satisfy at least one of: api, conversationsv3:read. API access tokens may satisfy a listed scope through the configured scope hierarchy; OIDC tokens are checked against their scope claims. Legacy JWT authentication does not use this scope check. Authentication, role, tenant, and applicable feature or plan checks still apply. For HTTP 403, check the credential type, applicable scopes, roles, and workspace access; 403 does not always mean a missing scope. Authentication/authorization failures do not guarantee a JSON response body.
