Howdy!

I am setting a redirect\_uri that has query parameters in the authorization URL as: redirect\_uri=[https://srv1.cameroncollective.com/oauth/callbacks?next=profile](https://srv1.cameroncollective.com/oauth/callbacks?next=profile)

The callback request getting back to my server looks like the query parameters are getting sliced and diced a little the field is there, but the value is dropped. Here’s the callback request info:  
GET ‘/oauth/callbacks?next&code=$$$redacted$$$’\>

Any thoughts?

Thanks in advanced.

Hey, [@cameroncollective](https://community.hubspot.com/u/cameroncollective)!

I ran a quick test with my own app and was able to pass `?custom_parameter=foo` to my redirect URI by encoding it as `%3Fcustom_parameter%3Dfoo`. If you try the same, what happens?
