Get Started: Discover the API

To begin consuming the GraphQL APIs, you must first know where they are, what operations you can invoke, and how to invoke them.

Because Liferay DXP’s GraphQL APIs leverage the official specification, you don’t need a service catalog. You only need to know the URL from which to discover the rest of the API.

Liferay DXP’s GraphQL APIs are available here:


For example, if you’re running Liferay DXP locally on port 8080, the URL for discovering the GraphQL API is


To inspect the GraphQL endpoint, use a GraphQL client, such as Altair (a Chrome extension) or GraphiQL.

You don’t have to be authenticated to inspect the live documentation, but you must to be able to make requests. There are several ways of authenticating in GraphQL APIs (explained here) but the simplest way to test APIs locally is to use Basic Authentication, setting an Authorization header in Altair (first icon on the left). Remember that Basic Auth is a BASE64 transformation of user:password. This means it’s insecure, and should never be used in production.

Most tools that introspect the GraphQL schema can autocomplete your query or fill all the fields in for you.

For a list of tools such as client generators, validators, and parsers supporting GraphQL, see Awesome GraphQL. Leveraging GraphQL provides standards support, extensive automatic documentation, and industry-wide conventions.

Unique endpoint and versioning

In contrast with the REST APIs, where endpoints are deployed by suite (headless-delivery, headless-admin-user…), GraphQL APIs are deployed under the same endpoint (/o/graphql). That way we can easily add relationships between entities to leverage GraphQL’s powerful request characteristics.

Liferay DXP’s GraphQL APIs also expose the latest published version of all entities available. If several versions of the same entity are deployed, only the latest one is exposed under the /o/graphql endpoint (REST APIs use different endpoints for different versions). This strategy follows GraphQL standards to avoid breaking versions by marking deprecated fields and always adding properties to an entity.
