Explore the GraphQL schema

Many GraphQL clients are support browsing GraphQL schema by taking care of introspection. In this page, we will cover GraphiQL and Altair clients.

GraphiQL and Altair are open-source GraphQL clients that provide a descent tool to compose a query, execute it, and inspect the results. And as a bonus, they also allow you to browse GraphQL schema.

​​ Prerequisites

Before you begin, do not forget to configure the API endpoint and HTTP headers.

The screenshots below are done from GraphiQL. However, Altair provides the same functionality and you will not find any difficulties following the same instructions to explore the schema.

​​ Open the Documentation Explorer

To open the GraphiQL Documentation Explorer, click the Docs link in the header of the response pane:

Clicking GraphiQL Docs link to open Documentation Explorer

The Documentation Explorer opens and displays a list of available objects:

GraphiQl Doc Explorer pane

Objects in the Documentation Explorer use this syntax:

object-name: object-type-definition

​​ Find the type definition of an object

When you first open the Documentation Explorer pane, the mutation and query root types display:

In this example, query is the name of a root, and Query is the type definition.

​​ Find the fields available for a type definition

Click on the type definition of a node to view the fields that it provides. The Documentation Explorer also displays descriptions of the nodes.

For example, click the Query type definition. The Documentation Explorer displays the fields that Query provides. In this example, the fields are cost and viewer:

To explore the schema, click the names of objects and definitions. You can also use the search input (magnifying glass icon) and breadcrumb links in the header.

​​ Find the arguments associated with a field

Click the type definition of the viewer field (gold text) to list its sub-fields. The viewer field provides sub-fields that allow you to query accounts or zones data:

Displaying viewer fields

The accounts and zones nodes take arguments to specify which dataset to query.

For example, zones can take a filter of ZoneFilter_InputObject type as an argument. To view the fields available to filter, click ZoneFilter_InputObject.

​​ Find the datasets available for a zone

To view a list of the datasets available to query, click the zone type definition (gold text):

Clicking zone type definition

A list of datasets displays in the Fields section, each with list of valid arguments and a brief description. Arguments that end with an exclamation mark (!) are required.

Fields section displaying datasets available

Use the search input (magnifying glass icon) to find specific datasets:

Searching a dataset in the Documentation Explorer

To select a dataset, click its name.

The definition for the dataset displays. This example shows the firewallEventsAdaptive dataset:

​​ Find the fields available for a dataset

To view the fields available for a particular dataset, click on its type definition (gold text).

For example, click the ZoneFirewallEventsAdaptive type definition to view the fields available for the firewallEventsAdaptive dataset:
