Replay a synthetic webhook to localhost safely
Use a one-time claim and local-only delivery without giving a cloud service access to your network.
Keep the target local
A safe replay client validates localhost or private network targets before it makes a connection.
Do not forward credentials
Drop Authorization, Cookie and provider signatures. Re-sign only with a dedicated sandbox secret when needed.
Design for duplicates
A local replay can retry. Use a stable event and replay identifier in your receiver.
