“deletion-request” ping

This ping is submitted when a user opts out of sending technical and interaction data to Mozilla. (In other words, when the datareporting.healthreport.uploadEnabled preference is set to false.)

This ping contains the client id. This ping does not contain any environment data.

This ping is intended to communicate to the Data Pipeline that the user wishes to have their reported Telemetry data deleted. As such it attempts to send itself at the moment the user opts out of data collection, and continues to try and send itself.

Expected behaviours

The following is a list of expected behaviours for the deletion-request ping:

  • Telemetry will try to send the ping even if upload is disabled.
  • Telemetry may persist this ping if it can’t be immediately sent, and may try to resend it later.
