Postman Tutorial - Generate Random Data With Dynamic Variables In Postman

Great tutorial! thank you so much!

automation thru postman explained very nicely. Appreciate your efforts for making this series of usefull videos.

I have a challange where I need to send checksum in every request. And check sum calculated on payload size. How I can send this checksum value automatically in every request.

The payload is in json format. Example payload:
I have logic to generate checksum, but I need to calculate and replace it before sending the request. Can I automate this calculation in postman??


{
"type": "people",
"id": "42",
"attributes": {
"name": "John"
}
"user-limit": 4,
"checksum": 211856345
}

Here checksum calculated for the below json payload first, and then added checksum.

{
"type": "people",
"id": "42",
"attributes": {
"name": "John"
}
"user-limit": 4
}

excellent
