Can a query parameter be included in the App Store redirect URL?

[claudiovarela]

Hi everyone! 

I have what I'm hoping to be a very simple question.
When setting up an App, users will eventually land on this page to confirm installation 👇

https://{shop}.myshopify.com/admin/oauth/authorize?client_id={api_key}&scope={scopes}&redirect_uri={redirect_uri}&state={nonce}&grant_options[]={access_mode}

can the REDIRECT_URI include a query parameter like this? 👇

https://example.org/some/callback?my_query_parameter=param_value

This might be a silly question, but I ask because the confirmation redirect includes shopify's own query parameters 👇 and I'm not sure if it would mess it up

https://example.org/some/callback?code={authorization_code}&hmac=da9d83c171400a41f8db91a950508985&host={base64_encoded_hostname}&shop={shop_origin}&state={nonce}&timestamp=1409617544
