This endpoint lets you create new registrants for one of your upcoming event sessions. Make sure to fill in all the required attributes (either native mandatory ones such as
last_name, but also custom fields that you may have created for this event in the app).
In order to provide the avatar of a registrant, you can specify a public URL towards an image file. Livestorm accepts PNG, JPG and JPEG files.
Beware of rate limits
If you're using this endpoint to create multiple registrants at the same time, don't forget to check our API rate limits, which limit you to send up to 5 requests per seconde. In this case, we advise you to use a 'throttle' or 'debounce' strategy.
