Converting JSON string from an API response to a flow service document type

Know how to convert JSON string from an API response to a flow service document type.

1. In the flow editor, select the flow function Client service to invoke an HTTP service to submit a HTTP request to retrieves results from the third-party API endpoints.
2. Use the bytesToString service to convert the HTTP response from bytes to a string.
3. Select the flow function JSON and use the jsonToDocument service to convert the JSON to a document.
   The document is ready for use as it is parsed, structured and accessible via pipeline variables.
4. Add Transform Pipeline to group the variables that you want to send in a response and drop all unwanted variables.
5. Run the flow service.
   The result is a document containing data received from a third-party API, transformed from raw byte data into a JSON format and then into the expected output document for further use.
