Subscribing to Entities from Centra GraphQL

​

Steps

• Go to Connections -> Incoming and create a new incoming configuration and select Centra - GraphQL Subscriber as the subscriber.
• Add any Request URI that you need to add from the Base URI from Client.
• Select the HTTP Method you want to subscribe to from Centra GraphQL (The default is POST).
• Add any request data in the request parameter that you needed to subscribe to the entity.
• You can optionally add a transformer to transform the request parameters into something you need.
• Select the Centra GraphQL Client to use.

​

General Concept

We follow Centra GraphQL documentation on building this connector so you can easily use the connector based on Centra GraphQL API Reference. Request URI It’s the Endpoint you want to subscribe from Centra. Request Method It’s the HTTP Method that you want to use, we recommend using post as default method. Request Parameters These are the parameters you can provide to get the needed entity based on Centra GraphQL API Reference. Please look at the example below on how to fill the Request Parameters field when trying to fetch products using some query parameter. Input Transformer Any transformers set here will be executed after the Request Parameters are loaded. So, you basically can add any transformer to provide and transform the request parameters into anything you need either as path parameters and/or as query parameters of an entity. HTTP Client It’s the HTTP Client configuration or prototype you will use to access Centra GraphQL.
