# Debug Pings

For debugging and testing purposes Glean allows to tag pings, which are then available in the Debug Ping Viewer1.

Pings are sent to the same endpoint as all pings, with the addition of one HTTP header:

X-Debug-ID: <tag>


<tag> is a alphanumeric string with a maximum length of 20 characters, used to identify pings in the Debug Ping Viewer.

See Debugging products using the Glean SDK for detailed information how to use this mechanism in applications.
