Hi @robeeen,

Welcome to the community :clap:

Looks like your use case should be fairly simple, but we have to modify our approach.

First, to get some clarity, are you expecting the example you provided to be the body of a single “bulk” request? If so, we’ll have to create the proper JSON field to match this exactly, and reference it exactly.

I would first go about doing this without the json file, and putting it manually in a single request. Then from there, take the body and put that JSON into its own JSON value in a file, and then reference that file fully.

Unless you have a need to manipulate the other values at run time, you can just reference the body as a single variable.

Show us once you’ve made a single request, with all these values, and we can go from there.
