Messages

Enviar mensaje de texto libre

Envía un mensaje por WhatsApp en nombre del business — texto libre, archivo multimedia, o ambos (texto como caption del archivo). La conversación debe estar dentro de la ventana de 24h (último mensaje del cliente < 24h atrás); si está cerrada, la respuesta es WINDOW_CLOSED (422) y el cliente debe enviar un template primero para reabrirla.

Variantes según body:

body sin file_uuid → texto libre puro (max 4096 chars).
file_uuid sin body → archivo solo (imagen/video/audio/documento).
body + file_uuid → archivo con caption (max 1024 chars). Excepción audio: WhatsApp no soporta captions en audio — si el file_category resuelto es audio y viene body, la API responde INVALID_REQUEST (400) con mensaje explícito. Envía el audio sin body, o manda texto libre en un request separado.

Flujo para enviar con adjunto:

Sube el archivo con POST /files/request-upload → obtén upload_url y file_uuid.
Haz PUT del binario al upload_url directo a Supabase Storage (no pasa por este server).
Confirma con POST /files/confirm → el archivo queda upload_status='confirmed'.
Llama a este endpoint con ese file_uuid. El file_category del archivo determina el tipo de mensaje WhatsApp (image / video / audio / document).

El file_uuid solo puede usarse una vez “lógicamente” — nada impide reusarlo en múltiples mensajes (el archivo en Storage es el mismo), pero cada envío genera un message_uuid y wamid distintos.

Guards aplicados:

Ventana 24h (siempre, texto y media).
Wallet de visión (solo si file_uuid) — si el business no tiene tokens de visión, el AI no podría procesar respuestas que referencien el multimedia y la API rechaza upfront con VISION_WALLET_BLOCKED (402).

Autorizaciones

Authorization

string

header

requerido

API token emitido desde Settings → API Token del dashboard 1TO1 AI. Enviar en header Authorization: Bearer sk_1to1_...

Parámetros de ruta

slug

string

requerido

Slug del business, case-insensitive. Debe coincidir con el business del token.

Ejemplo:

"acme"

Cuerpo

application/json

conversation

object

requerido

Identificador de la conversación — exactamente UNO de los cuatro campos debe venir. Orden de resolución: uuid > whatsapp_user_id > username > phone. El lookup filtra por el business del token (defense in depth cross-tenant). Resolver por phone o username puede devolver 409 (PHONE_NUMBER_AMBIGUOUS / USERNAME_AMBIGUOUS) cuando varios contactos comparten el identificador — aplica a cualquier endpoint que acepte esta referencia.

Show child attributes

body

string

Contenido del mensaje. Sin file_uuid es texto libre (max 4096 chars). Con file_uuid actúa como caption del adjunto (max 1024 chars). Opcional solo si file_uuid viene — al menos uno de los dos es obligatorio.

Required string length: 1 - 4096

Ejemplo:

"Hola! Gracias por tu compra."

file_uuid

string<uuid>

UUID de un archivo ya confirmado via POST /files/confirm. El archivo debe pertenecer al mismo business del token y estar en estado confirmed. El file_category determina el tipo de mensaje (image, video, audio, document). Los stickers (image/webp) no se soportan por esta ruta.

reply_to_uuid

string<uuid>

UUID de un mensaje previo para citar (reply). Opcional — se ignora si el mensaje referenciado no pertenece a la conversación o no existe.

Respuesta

Mensaje creado y enviado a Meta. wamid es el id asignado.

message_uuid

string<uuid>

requerido

UUID interno del mensaje creado. Útil para correlacionar con webhooks o reintentos.

wamid

string

requerido

ID del mensaje asignado por Meta (wa-message-id). Se usa para trazar en la Graph API de Meta o para reacciones.
