Send a message (session, template, or interactive)

Dispatch by type. Session types (text|image|video|audio|document|location) and interactive (button/list/carousel) are gated by the 24h customer-service window (closed → 409 outside_24h_window); template is exempt. Supports the optional Idempotency-Key header (safe retries — a completed key replays the stored response). Reserves 1 unit of the daily send quota.

What you must send. Beyond type, the required fields are conditional, so they cannot all be marked required in the schema below:

Session and interactive types need exactly one recipient — conversationId or phone (E.164, e.g. +27821234567) or bsuid — plus content. For text, content is the message body; for media types it is the URL or media id; for interactive it is the button/list/carousel payload. Omit the recipient → 400 missing_recipient.
template needs a recipient spelled to or phone (an E.164 number — conversationId/bsuid are not accepted on this branch), plus a template name and a language.
Template name and language each accept two spellings — name or templateName, and language or languageCode — because the endpoint takes both the friendly and the strict form. Send one of each; if both are present the friendly spelling (name / language) wins. Missing → 400 missing_template_name / 400 missing_language.
Template variables go in either raw Meta components or the structured header/body/footer/buttons form. If you send both, raw components takes precedence and the structured form is ignored. A variable count that disagrees with the approved template is 400 template_variable_mismatch.

Authorizations

Authorization

string

header

required

Project API key issued in Settings → API keys. Send it as Authorization: Bearer pk_live_….

Headers

Idempotency-Key

string

Opt-in idempotency key for safe retries of this send.

Maximum string length: 255

X-Paige-Project

string

Target project id, for an MCP OAuth bearer (mcp_at_…) attached to more than one project — get ids from GET /v1/projects. Matched case-insensitively.

Omit it and a READ falls back to the connection's default project; a mutation (any non-GET) on a connection with 2+ projects is rejected with 400 project_required — a write is never defaulted to a guessed project. A connection with exactly one project never needs the header.

Scopes are checked against the SELECTED project only, never a union across the connection.

For a pk_ API key the header selects nothing — one key is one project's context — but it IS validated: omit it and the key's own project is used, send it and it must name that project, otherwise the call is rejected with 403 project_not_attached (a blank value is 400 invalid_project_header, as above).
