Let's explore the possibilities of Azure DevOps in integrating with the external services: why not to receive the status of build in our Slack team? Or maybe create a card in Trello for every deploy? What about dozen of other out-of-the-box integrations? But what if we want to go deeper and build the integration with our own service - for example, with a PWA sending Push notifications about the next successful release. It's also possible - we'll have a look at Azure DevOps webhooks. Btw what are we going to use to build and deploy that custom notifications service? Sure! Azure DevOps again!
