Sending an SMS

TextLink offers a versatile SMS API, tailor-made for developers who seek straightforwardness in sending and receiving SMS. The act of dispatching an SMS is inherently simple, and we aim to reflect this simplicity in our API. We ensure it's user-friendly, eliminating the need for elaborate account setups, mandatory logins, or additional recurring charges.

Getting an API key

To be able to use TextLink for sending an SMS or user verification, you first have to register an account, after that you are going to get 500 free messages per month, which you can use to send SMS or verify user request anywhere in the world.

After you have registered an account, your API key will be available on the API console.

Sending an HTTP POST request

To send an SMS, you can send the following POST request with tool of your choice (like Postman), or use any of the programming languages that support REST API calls.

Send an SMS wih the custom body to the recipient phone number.
