The purpose and usage of this API is to send an authorization code to a user via SMS that the user can then enter into your application to verify their identity.

To allow a greater range of usage there are several parameters that can be defined when calling the API:

1. phone - where the sms should be delivered
2. appName - your application / business / brand name, to be included in the message
3. code - an optional parameter that allows you to use a code you have already generated for the user
4. codeLength - an optional parameter that allows you to define the length of the generated code

When calling the API, both phone and appName are required, and will be validated.
If either one is invalid, no SMS will be sent and the API will return a “false” success message.

If code and/or codeLength are not passed over, the API will default to generating a 4-digit code.
