When submitting multiple numbers, you should use the POST method rather than the GET method.To send to a list, set the DestinationAddress parameter to “List” and add a new parameter “ListName” with the name of the list to send to.For a group set the DestinationAddress parameter to “Group” and add a new parameter “GroupName” with the name of the group to send to.If the send is successful, the API will return 1. If not, a negative error code will be returned.Note that these sends may occur in the background if the group/list contains more than 200 entries.

Once there you will be able to choose the URL to forward to, whether you want to forward with the GET or POST method and what to pass with the auth parameter. (The auth parameter is a passthrough variable designed to add some security by having a password passed through)

source – the phone number that the message came from

dest – the VMN that the message was received on

msg – the body of the message

id – the ID of the message

receivedts – the timestamp that the message was received by us in the format YYYY-MM-DD HH:MM:SS
