SMS Sender ID (also referred as to SMS Sender Name) is the information that is displayed to the recipient as the sender of the SMS when a message is received at a mobile device.

Phone number of the receiver. To send to multiple receivers, separate each entry with white space (‘ ’) or comma (,). Phone number must include country code, for example, a Malaysian phone number will be like 60123456789.

Contents of the message, URL encoded as necessary (e.g. Text+message+test%21). If you are sending binary content, this will be a hex string. For example, 030616AE966C6F...

Requests can only be made to domains associated by this application.

These params will be URL-encoded and appended to the URL when making the request.

Authentication headers are included automatically

Zapier will apply these optional headers and values to the request in addition to any headers created as part of the authentication mechanism.

Zapier will pass this along raw. If you would like to provide complex JSON, try a "Code by Zapier" step to build the structure and pass it along here. For example, {"foo": "bar"} is perfectly valid.
