POST /sms
Create and send an SMS resource
| Parameter | Type | Description | NULL |
|---|---|---|---|
| from | string |
The SMS sender. If empty, a shared shortcode will be automatically selected depending on the destination carrier. Otherwise, it must be either a dedicated shortcode, or alphanumeric (at least one character - cannot be digits only). Max length = 11 characters. Depending on your account configuration, you may have to ask our support team to authorize custom Sender IDs. "SMS" is always authorized. Format: sms_sender (a-zA-Z0-9, space, dash, underscore - must contain at least one alpha character) |
NO |
| to | string |
The SMS recipient. Format: phone_number (International E.164 format "+CCNSN". Example: "+16467890800", "+447890123456", or "+33678912345") |
NO |
| body | string |
Text message. We auto-detect the encoding needed (GSM 03.38 or UNICODE), or you can force the encoding with options.force_encoding (see the "options" parameter). You always send UTF-8 JSON strings - encoding is done at SMS interconnections level. Depending on the encoding, messages may be split into parts at 153 (GSM) or 67 (UNICODE) characters. One SMS sent with this method may be billed as multiple SMS parts. You can check the number of parts sent with the method "sms.get". If you are using a custom sender, you can use the special string %STOPNUM% -- it will be replaced by the STOP number. |
NO |
| options | object |
SMS Options. Omit parameter to use default values. Object: SMS.Options |
YES |
| Type | Description | Format/Object |
|---|---|---|
| string | SMS ID | Format: hash (Unique object identifier) |
