What is SMS/Messaging API?

An SMS API (Application Programming Interface) is a set of tools and protocols that allow developers to integrate text messaging capabilities into software applications or websites.

With the help of SMS API, you can send SMS to your target audience through code and automate messaging based on predetermined conditions. One such condition is the trigger for payment requests, which prompts the API to send out an OTP for verification.

SMS APIs provide a way for developers to send and receive SMS messages programmatically by making HTTP requests to an SMS gateway that handles the SMS delivery. The SMS gateway acts as an intermediary between the sender and the recipient, converting the message into a format that can be transmitted over the SMS network.
