Requests with params containing ":" character

[JohnDuff44]

Hello,

I would like to request an API but params require a ":" character.
Something like : /api/search?query=toto:chips+tata:bacon

In grafana, I've created the new source with the url /api/search
And when I create a new panel with params :

key : query
value : toto:chips+tata:bacon

It doesn't work.

I also tried :

key : query
value : toto%3Achips+tata%3Abacon

But still doesn't work

Is there a way to make it work ?

Thanks
Have a good day,
