MMO-DEV WEB API

MMO-DEV WEB API is a GraphQL API for project websites, the launcher, game accounts, payments, shop flows, support, and user settings.

All calls use the project GraphQL endpoint /graphql. Clients send an allowed document ID (documentId) and its variables (variables). Available documents are listed in the operations reference.

If the API terminology is new to you, open the glossary: it explains documentId, variables, X-Project-Context, sessions, servers, and warehouse.
