Hi,

I believe someone has done this, but they’re not going to see this topic in order to give you a reply.

What you can do is follow these steps to get started:

1) Review and follow the examples in the documentation:
a) https://github.com/eventespresso/event-espresso-core/blob/master/docs/C–REST-API/ee4-rest-api-introduction.md
Especially important: Learn how to use the discovery endpoints and Authentication.
b) https://github.com/eventespresso/event-espresso-core/blob/master/docs/C–REST-API/ee4-rest-api-writing-data.md
2) Create a registration via Event Espresso’s UI in the WordPress dashboard
3) Review the site’s database tables to see everything that was just written to the database. You’ll note that Event Espresso tables have an _esp_ prefix. Also note that an attendee custom post type is also written to the _posts table, and specific entities within event related tables need to be updated when a registration is added. For example, a ticket’s sold count needs to be incremented when an approved registration is added.
4) Learn how to read/GET the related registration data using the REST API:
https://github.com/eventespresso/event-espresso-core/blob/master/docs/C–REST-API/ee4-rest-api-reading-data.md
https://github.com/eventespresso/event-espresso-core/blob/master/docs/C–REST-API/ee4-rest-api-GET-including-specific-fields-and-related-entities-in-results.md
Here you’ll note how to do GET requests for registration-related data, which you’ll use much of the same syntax for POSTing data.
5) Once you’ve gotten this far, you can start putting together REST API requests to write to the database
