How to send a POST request of base64 string from body.

[anishvarma01]

I have a fiddler post request. In that the body is base64 string and there is an header "Fiddler-Encoding: base64".

Can i make same request through postman? I tried it but i not able to decode the string. Does postman has this feature like fiddler?

Hi @anishvarma01,

We do not support changing request body through scripts at the moment. A possible workaround for your use case is to use environment variables and keep base64 request body in the a variable. Then decode the base64 string from the environment in the pre-request script and use it as the request body. See the below screenshot for an example:

Request body:

Pre-request script:

Environment variables:

Closing this issue for now. If you are interested in mutating request body from pre-request script, we are tracking it in #4808.
