# SendSmsMessage

POST https://api.voximplant.com/platform_api/SendSmsMessage

Sends an SMS message between two phone numbers. The source phone number should be purchased from Voximplant and support SMS (which is indicated by the **is\_sms\_supported** property in the objects returned by the \[GetPhoneNumbers] Management API) and SMS should be enabled for it via the \[ControlSms] Management API. SMS messages can be received via HTTP callbacks, see this article for details.

Allowed roles: `Owner`, `Admin`, `Developer`, `CallsSMS`.

**Example request:** Send the SMS message with the text "Test message" from the phone number 447443332211 to the phone number 447443332212.

## Authentication

- `Authorization` header (bearer token, required) — Voximplant Management API uses signed JWT tokens generated from your service-account private key. Pass the token in the `Authorization` header as a Bearer value: ``` Authorization: Bearer $VOXIMPLANT_TOKEN ``` See [Authorization](/api-reference/management-api/authorization) for ready-to-copy snippets in bash, Python, Node.js and Go that turn your `credentials.json` into a token.

## Request

### Query parameters

- `source` (string, required) — The source phone number
- `destination` (string, required) — The destination phone number
- `sms_body` (string, required) — The message text, up to 765 characters. We split long messages greater than 160 GSM-7 characters or 70 UTF-16 characters into multiple segments. Each segment is charged as one message
- `store_body` (boolean, optional) — Whether to store outgoing message texts. Default value is false

## Response

### 200

Successful response

- `result` (integer, optional)
- `message_id` (integer, optional) — Message ID
- `fragments_count` (integer, optional) — The number of fragments the message is divided into
