This helps insulate providers from consumers, which makes the system more robust and fault-tolerant because providers do not depend directly on consumers. The recommended solution is to ingest and buffer your webhooks during the downtime period, and the component to help achieve that is known as a message queue.Ī message queue helps decouple your webhook provider from your webhook consumer, as it sits in between the two. This leads to information being lost and if there is no way of getting the webhooks again, that information may be lost forever. The main issue with server downtime is that webhooks are continuously sent to your endpoint but your server cannot process them. Get familiar with CRON expression syntax.How to manage webhook downtime scenarios for reliability Store credentials, connection strings, and even authorization tokens in the Function App > Application Settings > App Settings or Connection Strings If you delete and re-create a Function with the same name, it may populate the template with old, cached content.
