Participant API Legacy

The Participant API is in legacy mode. Global access to participant data will soon be forbidden and the Participant API deprecated. If you start a new project or are using the Participant API to access your own competition data, you have to use the current API (previously named Organizer API).

API reference ›


The Participant API allows you to register users for tournaments that you do not organize. If you want to register users for your tournaments, please use the Organizer API.

The Participant API is appropriate if you want to:

  • Allow users to register for tournaments that you do not organize.
  • Allow users to modify their registrations.
  • Allow users to check in to their tournament.

The API is divided into several sections. Each section provides the different access points related to a single entity.


OpenAPI 3.0 specification

We also provide you with the OpenAPI 3.0 specification schema of our API. This specification allows us to describe our API with a standard format. Developers can import these files into interactive REST clients (such as Postman or Insomnia) or use these files to generate code and quickly perform calls to our API.

You can find more information on the OpenAPI initiative website.

You can also find a list of tools developed for OpenAPI on the OpenAPI tools website.
