Register your account

Head to https://bestsms.au/signup to create a new account.

A test account is possible, however creating a commercial account and using the Mode=Test function of the API is simpler to use when you’re ready to push your application live.

After completing the sign up form, a sales consultant will manually activate your account. This may take one business day. Once the account has been activated, you will be able to Create a new API user token.


Create a new API user token

Using the API will require a Sender and Token pair to authenticate with the API.

You can generate this using the Web Dashboard under: Users | Outbound Users | Create | API Options
Sender = Sender
API Key = Token


Understanding the API basics

When submitting a message via HTTP, the server will respond:
  200 OK, OK Thanks
  400 BAD REQUEST, %ERROR REASON%
  500 Internal Server Error

Once the message delivery completes, a status report can be dispatched to your software. Reply messages can also be captured.
