Example 2 - Node Responds (HTTP)

Build a complete FlowSync request-response cycle in which a mapping processes incoming HTTP requests and publishes responses.

Building upon Example 1 - Node with Transaction Mode (HTTP), this configuration demonstrates how to set up a complete request-response cycle using FlowSync. The service includes a mapping that processes incoming HTTP requests and generates defined responses. When a request arrives, the system automatically creates and publishes an appropriate response message, preventing the timeout scenario seen in the previous example.

• To call the HttpNode in the example below, run the following command:

curl --insecure \
--location 'https://127.0.0.1/data/flowsync/example2' \
--header 'Authorization: Bearer <replace with your token>'
