# Send message

> Send individual WhatsApp Business template messages

## Description

This endpoint allows you to send a WhatsApp template to an individual recipient. It implements a **fire-and-forget pattern**: when sending the message, it returns a `message_id` (Meta's wamid) that you can use to check the message status.

The API validates the template, resolves the variables, and sends the message through the Meta API synchronously.

## Authentication header

<ParamField header="X-API-Key" type="string" required>
  Your Mindo API Key. Format: `mindo_xxxxxxxxxxxxxxxxxxxxxxxx`
</ParamField>

## Body parameters

<ParamField body="phone_number_id" type="string" required>
  Meta's WhatsApp phone number ID from which the message will be sent. You can get it from the [Get business accounts](/en/api-reference/cuentas-negocio/obtener-cuentas) endpoint.
</ParamField>

<ParamField body="template_name" type="string" required>
  Name of the approved template to send. Must have `APPROVED` status in Meta.
</ParamField>

<ParamField body="language" type="string">
  Template language. Default: `"es"`. Examples: `"es"`, `"en"`, `"pt_BR"`.
</ParamField>

<ParamField body="recipient_phone" type="string" required>
  Recipient's phone number in international format (e.g.: `"+5491112345678"`). No spaces.
</ParamField>

<ParamField body="variables" type="object">
  Custom variables for the template. Keys must match the variables defined in the template.
</ParamField>

<ParamField body="button_variables" type="object">
  Variables for dynamic template buttons. Keys use the format `button_0`, `button_1`, etc., where the number corresponds to the button index (starting at 0). Values are the dynamic suffixes or payloads for each button.

  **Important:** URL buttons only support 1 variable.

## Message statuses

The message `status` field can have the following values:

| Status      | Description                                 |
| ----------- | ------------------------------------------- |
| `sent`      | Message sent to Meta successfully           |
| `delivered` | Message delivered to the recipient's device |
| `read`      | Message read by the recipient               |
| `failed`    | Message send failed                         |

<Note>
  The individual status lookup endpoint (`GET /api/v1/meta-templates/messages/\{message_id\}/`) will be available soon. In the meantime, you can use the returned `message_id` for internal traceability.
