Your bot doesn’t have to be just a chatty assistant. It can also handle more advanced actions for you such as completing purchases, sending receipts and sending updated data from your databases. You can do that using webhooks.

Webhooks, also called a web callback or HTTP push API, are the API concepts that are getting more and more popular. Thanks to their lightweight and speed they provide data between applications immediately. With webhooks, you can pass and retrieve information from a matched interaction to your web service.

  • you can set up separate webhooks for each interaction

  • pick the language you like to create webhooks: PHP, Node.js, Java, JavaScript, C++ etc.

  • webhooks returns data to your bot, that’s why responses from webhooks are added to bot responses
