JSON API
The JSON API plugin enables you to integrate your backend into your chat bots on Smax bot.
It allows you to
- Generate dynamic content
- Get and set user attributes
- Redirect users to another block in the bot
- Create postbacks
You can use GET and POST requests - the max. timeout is always 10 seconds. There are four options to enter data that will be sent with your request:
1. URL — This field supports user attributes, they will be URL-encoded with your request
2. Full JSON profile (POST requests only) — This will send all the user attributes of the user to your backend
In your responses, you can
- combine several messages in one answer by sending several dictionaries in the messages array.
- use any content type header.
- send an empty response to not show the user any dynamic content.
