Purge extension for Fastly
With this plugin you can add a build step to your Azure Devops release pipeline that makes either a Purge All or a Purge by Surrogate Key request to the Fastly management API for a specific service. If the request is successful, the task will be marked as completed and the release pipeline will continue to the next task. If it fails (or times out), the release will be marked as failed.
