DTM used to have a deploy webhook, used together with the download zip option, when publishing changes / new library (so our code was made aware of the change and could download zip). Cannot find similar in Launch?
This was recently answered by Jeffrey Walter on the Launch Developers slack channel (launch-developers.slack.com)
I'll summarize here:
Launch provides the ability to establish callbacks (Webhooks) that will be POSTED to when a subscribed audit event happens.
An Audit event is described as [resource]:[action] using the resources and actions shown below.
Subscriptions for callbacks are set up using the Launch API as shown here: Launch Callbacks via API
