Erxes · GraphQL Specification

Erxes GraphQL API

Erxes is an open-source experience operating system (XOS) built on a GraphQL Federation architecture using Apollo Router. The API is organized as a microservices monorepo where each plugin (contacts, inbox, sales, operations, automations, etc.) exposes its own GraphQL subgraph that is federated into a single unified gateway. Core types such as `User`, `Customer`, `Company`, `Tag`, and `Product` are shared across subgraphs via Apollo Federation `@key` directives.
