The legacy snippets implementation allows for the replacement of several values according to release channel, version, locale, and several others via the browser.aboutHomeSnippets.updateUrl pref: https://snippets.allizom.org/%STARTPAGE_VERSION%/%NAME%/%VERSION%/%APPBUILDID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/ We should allow for this in provider endpoints as well in ASR since snippets will continue to support this.

Are all of these parameters in the URL still used/needed by the snippets service or only some?

Used always: - startpage - locale - channel Other fields that have been used: - Name - Version - AppbuildID - OS Version What's the reasoning behind changing what we have?
