# Adding URL parameters to web app URLs
2022-01-06 A CID builder tool (opens new window) has been created to add CID parameters to the URLs. This tool takes care of all the logic that has to be applied to the standard or web app URLs.
As of today, the tool is still in the development process and should be finalized shortly. Zach Bonavita is the person who is in charge of CID process, contact him for any questions or clarifications.

Sponsorship and supporter center are the two pages that are build as one page web apps. They contain dynamic URL changes that happen only after the page is loaded.
In some cases URL parameters may need to be passed to those pages. If the URL parameters are not properly passed through the web app will reload the page with a rewritten URL.
# Conditions for URL parameters
- All web app URLs must contain
#!/in the URL. This will tell the web app the path of the virtual page and it will not try to create a new one. - Additional URL parameters can be included before or after the
#!/.
For example, both following URLs should remain the same after they are loaded in the browser.
