I am making a collection where after hitting each API, I need to validate the response (in JSON) against my expected JSON which I have extracted after manually hitting the API first. I already know that I can pass this expected JSON as any other data variable from the CSV but the challenge is:

  1. The expected JSON is very large, and I have to do this for multiple APIs in the collection across multiple iterations
  2. The csv becomes VERY HEAVY and hard to maintain for any changes I need to make as its very tough to recognize where the JSON ended (I hope you can imagine).
  3. I want to use the same expected JSON across multiple collections, so I cannot "reuse" the same JSON and I am forced to write it everywhere, making it a maintenance nightmare.

I am looking for a way by which I can store the expected JSON in an external text file and a mechanism to provide the name/path of the txt file in the data.csv so as to centralize the expected JSONs.

It's not possible to directly work with local files in Postman.

What you can do is to setup a (local) server, that you send a request to, and the response would contain your expected JSON, which you then can process in Postman.

For writing files to your local file system it's described here: https://blog.postman.com/write-to-your-local-file-system-using-a-postman-collection/ You could modify this for reading files.
