Hi,
I have some tags that contain equal signs in it. When using the API, I can't filter those particular checks.
For example, to get the checks that match "a=b", the query url would look like:

https://hc.example.com/api/v1/checks/?tag=a%3Db

With the tag a=b urlencoded to a%3Db because the query tag=a=b would be nonsensical.
This does not return any matches. I tried to figure out why this does not work.. without any result so far...
I did test tags with other funny characters, like %, & and $ in it (urlencoded) and that seems to work fine. A tag with ! in it also fails to be queried.

Bests,

Bram

https://hc.example.com/api/v1/checks/?tag=a%3Db

This looks good and should work. How does the request look in server's access log? Maybe the encoding goes wrong on client side, and the server sees something else.

Excuse me, sorry for bothering you. There was an error in my testing code that altered the tags and therefore could not find them anymore. ;-)
