Sending SMS via HTTP

Send an SMS text message to a mobile phone.

SMS is standard GSM 7-bit and should conform to the GSM ASCII character set.

We recommend sending to no more than 500 comma separated numbers in a single API call.

For UK mobiles the number should begin 447 or 07. For non-UK mobiles the number should begin with the country code. The number should never contain a "+" at the beginning.

By default we assume clients do not encode their messages as UTF8 when passing them to the SMS Expert API. However if you wish to do this then please inform us so that we can switch your account to handle UTF8 encoding.

API response This function will return error/status response codes and messages as plain text on two rows. The first row is simply a header row.

The second row consists of a 3 values each separated by a "|" pipe character: error code, error text and submission reference.

error code|error text|submission reference
0|sms submitted|eb725f96b4b094d5f8318741cc1a545f-2

If the error code indicates a failure (any non-zero value) then the submission reference should be ignored.

If the error code is "0" (zero) this indicates a success and the submission reference should be recorded so that it can be matched up in future with the delivery receipt.

The submission reference will consist of a 32 character reference followed by a dash and then a single digit. Only the 32 character reference is required when matching up the delivery receipt.

At the time of writing the following are the available error codes and associated messages...

    0|sms submitted|[32 characters]-[1 character]
    1|bad user details|0
    2|missing or invalid fields|0
    2|missing or invalid fields (no text)|0
    2|missing or invalid fields (too many text characters)|0
    2|missing or invalid fields (invalid long message)|0
    2|missing or invalid fields (type is blank)|0
