We are working on a SNOW solution to provide a custom table data to an external system using Scripted REST GET API.
External system has a list of sysids and would invoke the GET API with a request(JSON payload - object array of sysids). Expectation on service now is to query the custom table and return the record values in the response(JSON Payload).
So on the API GET resource I have tried to retrieve the payload as "request.body"; But this options looks not possible as request.body is allowed on SNOW only for POST/ PUT.
Please suggest if there are other possible ways to retrieve the request as JSON.
