How to pass variables in it it is not working for me

You should simply replace the "yourString" with your String variable.

“error”: “Unsupported Media Type”,

Could you also show how your HTTP Request is configured in both Studio and a working example using some other tool (i.e. Postman)?

This would help a lot.

Could you try passing the JSON in the Body field of the HTTP Request activity?

It accepts input as string, so you will have to escape all double quotes, like so:


There are other ways to pass this JSON input to this field, such as:

  1. Load it from a text file as is (no need to escape quotes) using the Read Text File activity
  2. Create it from scratch, more on that here.

I am not sure I understand your reqest.

Could you maybe post a screenshot how you would achieve the same in let’s say Postman (or any other tool of your choice)?

Hi, I am having a similar issue, but my Post Body request needs a variable type of DateTime, but I can pass only the String value, Let me know how I can change the datatype of my parameter.

2 posts were split to a new topic: HTTP Request configure button purges given variable parameters

Is this solved now? i am also facing similar issue
