If you need to reply to an inbound message with a message that has dynamic content, you can use a Reply with message returned by executing specified URL rule action. This rule will send an HTTP GET request to an URL of your choosing with the following querystring parameters:
|MessageId||An unique integer identifier for the message|
|Sender||The sender's phone number|
|Recipient||The recipient, this will be your Dynmark Long Number or a shortcode|
|Content||The content of the message|
|ReceivedDate||The date that the message was received in ISO 8601 format, e.g. 2015-02-27T14:49:10.0000000Z|
HTTP/1.1 200 OK
Content-Type: text/plain; charset=utf-8
Thank you for your message
Your HTTP GET handler should return an HTTP 200 OK status code and the response body should contain the message content that you want to be sent as an SMS. If the message content is empty or the HTTP status is anything other than 200, no SMS will be sent.
Although http is supported, using https is highly recommended to keep the transmitted data private.
