-### Passing custom parameters to the client on join
+### Passing user metadata to the client on join
 
 The HTML5 client supports a list of parameters that can be added to the `join` API call which modify the look and default behaviour of the client. This list is accurate as of BigBlueButton version 2.2.17 (build 937). These parameters override the global defaults set in `settings.yml`. As the parameters are passed on call to join, it allows for some powerful customization that can vary depending on which user is joining the session.
 
 Useful tools for development:
 
 - A tool like (https://meyerweb.com/eric/tools/dencoder/) is useful in the encoding-decoding process for the fields expecting encoded value passed (see below).
-- The [API mate](https://mconf.github.io/api-mate/) allows you to directly experiment with these custom parameters. To use the API mate, run the following command on your BigBlueButton machine: `sudo bbb-conf --secret`. This creates a link for you with your secret as a parameter so you can get started experimenting right away.

 To help you create/test valid API calls against your BigBlueButton server, use the excellent [API Mate](http://mconf.github.io/api-mate/) to interactively create API calls. API Mate generates the checksums within the browser (no server component needed) so you can use it to test API calls against a local BigBlueButton server.
 
-If you're developing new API calls or adding parameters on API calls, you can still use the API Mate to test them. Just scroll the page down or type "custom" in the parameter filter and you'll see the inputs where you can add custom API calls or custom parameters. New API calls will appear in the list of API links and new parameters will be added to all the API links.

 If your using API Mate to test recordings and want to query by `meetingID`, be sure to clear the `recordID` field first.  BigBlueButton's API supports querying for recordings by either value, but not both at the same time.
