Observation

• Types of issued events are application specific• Events are issued in the context of projects• Event handling is project or even team specific• End users configure event handlers

• This is really just “remote listeners”

Page 5: C/ALM Event Handling

Context

• Use Webhooks over Atom feeds

• “Listeners” are URLs the subject POSTs the event to

• The listener may be remote to interested application

Tasks (subject side)

• Define resource format of events• Make issued events discoverable• Define protocol for webhook registry• POST to registered webhooks

• Utilize existing process events

Page 8: C/ALM Event Handling

Tasks (consumer side)• Define a way to register webhooks

– [label, description, URL]

• Allow end users to configure webhooks– allow to browse configured friends for available events– allow to directly enter URL– allow to configure parameters for webhook – support on project area and team area level– take Web UI perspective

• Persist webhook configuration in the Foundation Storage Service

• Register configured webhook with subject’s registry

• Find reasonable integration in eclipse client

Open Issues

• Authentication

• Licensing

• When does the registration happen?

• How do we represent cross app event handling in process templates? In what kind of process templates?

Interesting Points of License Enforcement

• User needs licenses to register webhook, number of webhooks a user can register could be limited

• The total number of webhooks on a server could be limited

• The number of webhooks that can be called by the server for any given event could be limited.
