Rest API Request with parameter value containing spaces must be filled with %20

I noticed that I got a 400 response when testing an API where the value set for the parameter was containing a space. URL in katalon looked like this:
http://..***:8080/geoservices/geo/geoLoc?address=grote markt 1 brussel

when pasting in chrome for example, it turns into:


which seems OK.

I think it would be useful that we could write spaces in our value field instead of %20 for every space. Can this be corrected?

You’re bumping into the HTTP spec here.

Usually, you can use either…

  • grote%20markt%201%20brussel


  • grote+markt+1+brussel

At the end of the day, if the API is asking for an HTTP string, you need to supply one.

Sure, you are right, but remark that SoapUI & Postman both accept me entering space and then translating the space into %20 behind the scenes. Would be more user friendly, imho.

I agree.

But then you start wondering, does the API do all required rewriting, or just some?

There’s a whole bunch of entity/oddities to consider, if you go that route. Like I said before, at the end of the day, if the API is asking for an HTTP string, you better suck it up and give it one (just for sanity’s sake).

came to this thread while i facing the space issue as well.
so Katalon decided no solution for this at all?

I wouldn’t assume that, no. The API claims to do a certain job and it has certain requirements. You have to meet those requirements. That’s just how it is. Nothing much else I can say.
