The GraphQL Responders simplifies the use of GraphQL by providing a form view for configuring responses. Each Message Responder responds to incoming request messages that match its Responder Correlation criteria. Responses can be configured in a variety of modes, ranging from simple fixed messages to dynamic parameterized messages using a data source. Message Responders are protocol agnostic, but the transport protocol or API to access a responder is defined in the deployment configuration of the PVA.
You can create a GraphQL Message Responder tool directly from the Add Responder wizards. This responder is preconfigured as follows:
| Setting | Configuration |
|---|---|
| Response tab > Input Mode | Form JSON |
| Options tab > Request Handling > Convert incoming request to XML before applying responder correlation | Enabled |
| Options tab > Request Handling > Convert incoming request to XML using different message format than response | Enabled |
Form JSON input mode allows you to define and parameterize JSON payloads via a graphical interface (as described in Form JSON).
All of the available configuration options for this type of message responder are covered in Message Responder Overview.
