There is no one-size-fits-all solution for guaranteeing webhook ordering, as it depends on various factors such as the specific use case and customer requirements. Ensuring ordering can be challenging due to issues like failed deliveries, slow handlers processing events out of order, and race conditions. To address these challenges, designers can opt for payloads that provide enough information for customers to process them in any order, including using thin payloads with identifiers and metadata, or including entity modification dates in the payload. Another approach is to attach a monotonically increasing sequence number to events, but this also comes with its own set of issues. Ultimately, the best solution is to design webhooks that don't require ordering, as forcing delivery order can be fragile and prone to errors.
