# Send message

Archived

This command allows you to send one or more SMS messages. To send messages to your database of mobile numbers, you can call this command in a loop.

The server will respond with a unique identifier for each message (referred to as an API message ID). This API message ID can be used to [track and monitor the status of your message](broken://pages/IGu1kyKq8IyGrhIPmVnS). You can also send to multiple handsets in one single `HTTP/S` request (up to 600 messages). This is useful if you are sending the same message text to all handsets.

For high volume messaging, we encourage the use of persistent (keep-alive) `HTTP/S` connections. Multiple concurrent `HTTP/S` connections may also be used for additional performance.

```
POST https://api.clickatell.com/rest/message
```

{% hint style="info" %}
The REST API may respond with various HTTP status codes. See the full list [here](broken://pages/sX2rvw0QeyQCuvzuQ5GC).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.clickatell.com/developers-api-reference/developers-archive/sms-rest-api-overview/send-message.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
