APIs (Application Programming Interfaces) are tools that allow different software systems to communicate with each other. They enable you to send requests to a system and receive data back in response.

Using APIs, you can connect Zonka Feedback with other tools and platforms you use and set conditions to trigger SMS Surveys. Let's take an example. Say you're using a tool where you're storing information about new purchases made on your website. You can connect the tool and Zonka Feedback and call Zonka Feedback's API to send SMS when a new purchase is made. This way your customer will automatically get an SMS Survey Invitation as soon as the purchase is made and would be able to give you feedback in real-time while the purchase experience is still fresh in their mind.
