Base URL
The v26.0 segment selects the pinned Meta contract. Use a version supported by the method. Polymorfa-Version does not apply to Graph requests. Authenticate with Authorization: Bearer <token> and keep the method’s Meta-compatible request shape.

Session backends

Graph supports Linked Devices and Meta Cloud API sessions. The selected session determines which backend handles the request. This does not make every Meta operation available on every backend: unsupported operations return a Meta-compatible capability error. Credential scopes and session ownership still apply. Browse the resources under Graph API for method parameters, responses, and backend requirements. Linked Devices translate validated reply buttons, lists, and HTTPS call-to-action URLs into native messages. Interactive forms without a native equivalent return capability error 131026. Template creation, listing, and deletion require a Meta Cloud API session under the requested WABA. A Linked Devices-only WABA returns a Meta-shaped capability error with code 131026; it does not return an empty template list or a successful deletion. A Meta Cloud API WABA with no stored templates returns an empty list.
