How to add OTP messages to my App or website?

I need OTP messages for my app/website

You can use our SMS API to automatically send OTP messages or verification codes.
First, register/signup then login to your account and "Request API access", we will activate the API on your account same day.
Then you can start the testing and integration for free.
When you are satisfied with the service, buy credits and SenderID then go live.
Please note that we do not offer programming or integration services. You should hire a programmer for this task.
