GraphQL

With GraphQL endpoints, Datahub allows integrating Pimcore to other systems and services via GraphQL and test them with the integrated GraphiQL explorer tool right away.

Configuration

Configuration takes place in the endpoint configuration and offers following possibilities:

• General Settings
• Schema Definition
• Security Settings
• Custom Permissions

External Access

The standard endpoint is

/pimcore-graphql-webservices/{configurationname}?apikey={yourApiKey}

So if your configuration name is blogdemo and your apikey 123456 then your endpoint would be

/pimcore-graphql-webservices/blogdemo?apikey=123456

Here is a configuration how to override the standard endpoint

Queries

Depending on the configuration, the endpoint provides several queries to fetch data from Pimcore. As Datahub always creates a proper graphQL schema, also have a look at the generated schema to get details for the possible queries of a certain endpoint.

On the following pages certain generic aspects are explained, and a couple of samples are listed:

• For details on Document queries see Document Query Documentation.
• For details on Asset queries see Asset Query Documentation.
• For details on DataObjects queries see DataObject Query Documentation.
• For details on how to add custom queries see Add Custom Queries Documentation.

Mutations

Depending on the configuration, the endpoint provides several mutations to update data in Pimcore. As Datahub always creates a proper graphQL schema, also have a look at the generated schema to get details for the possible mutations of a certain endpoint.

See following pages for a general overview of possible mutations:

• For details on Document mutations see Document Mutation Documentation
• For details on Asset mutations see Asset Mutation Documentation
• For details on DataObject mutations see DataObject Mutation Documentation
• For details on how to add custom mutations see Add Custom Mutations Documentation.

Hands-On-Testing Using GraphiQL Explorer

GraphiQL explorer can be opened for an endpoint in an iframe within Pimcore or as an additional browser tab.

Events

It is possible to customize default behavior of graphQL endpoint with event listeners. For details see Events Documentation.

Output Cache

It is possible to keep a cache of the responses delivered by the endpoint, using the same default cache backend configured for Pimcore (Doctrine, Redis,...). This is specially useful to speed up the endpoint replies when it produces complex responses with many dependencies.

The cache can be enabled and configured with a configuration entry like this in your config.yml file:

#### DATAHUB OUTPUT CACHE
pimcore_data_hub:
    graphql:
        output_cache_enabled: true    # Enables/disables the output (responses) cache
        output_cache_lifetime: 20     # If enabled, for how many seconds each response will be cached

By default the cache is disabled but if it is enabled and you don't specify a value for output_cache_lifetime, its default value is set to 30 seconds.

Disable Output Cache for a Single Request (Only in DEBUG MODE)

Just add the parameter ?pimcore_outputfilters_disabled=true to the URL. This works in a similar way as the Pimcore's Full Page Cache.

Customize the Cache Behaviour

It is possible to customize some behavior of output cache with event listeners. For details see Events Documentation.

Note on Debugging With iGraplQL Playground

Open the settings and change request.credentials to include. Otherwise the XDEBUG_SESSION cookie header will get removed by default.
