You can easily create a GraphQL data source in Sigma Studio with feasible configurations. The GraphQL data source paves way for fetching the data from the GraphQL endpoint by passing the query in the request.
Note: You can also create datasource for REST webservice endpoint in this screen.
To create a GraphQL data source, perform the following steps:
On the home page of the Studio, click Connections on the left pane.
The connections created will be available in the Connections list on the right pane.
Click the Data Source icon on an existing Graph QL Web Service connection.
The Create new Data Source screen appears.
The Connection Name is a non- editable field and displays the unique name provided by you for the connection in the Connection screen, e.g. GRAPHQL_CONNECTION.
Enter a unique data source name in the Data Source Name field, e.g. GRAPHQL_DS.
Select the mode of the Data Source in the Mode section. In this screen user can create datasource for both GraphQl and other web services like REST API.
Note: By default GraphQL is selected as mode. If GraphQl is the mode, you can enter the data query in the Data query field.
If it is REST webservice you can input the request payload in JSON format in the data query field.
Select the request type in the Method Type field. The available method types are:
POST. If request type is POST method proceed to step 8
GET. If request type is GET method proceed to step 7
If request method type is GET, enter the relative path of the GraphQL endpoint in the Relative URL field to fetch the required data.
If the request method type is POST, enter the request query in the Data Query field, so that the data can be fetched from the GraphQL endpoint respect to the query provided.
