Webhook replay

Re-sending a previously received webhook payload through a workflow, typically after fixing a bug that caused the original run to fail. PURIST's infrastructure logs all incoming webhooks, enabling safe replay without data loss.

Expert insight

Most webhook providers offer a replay feature for resending a webhook that failed to be processed, but replaying a webhook that already partially succeeded (created a record before failing on a later step) can create a duplicate unless the workflow's replay handling is explicitly idempotent, checking whether the action already happened before repeating it.

In a real workflow

Failed Stripe events are replayed from the dashboard after a bug fix.
