Stripe webhook retries: what Stripe retries, and what your app still needs to do

Stripe already has a delivery retry mechanism, so it is reasonable to ask what another reliability layer adds. The short answer is that provider retries protect the handoff from Stripe to your endpoint; they do not make the rest of your processing durable or observable.

What Stripe retries protect against

In live mode, Stripe documents automatic retries for up to three days with exponential backoff when a webhook endpoint returns a failure or does not respond successfully. That gives a temporarily unavailable endpoint time to recover without an operator manually resending every Event. A timeout or HTTP 500 is therefore not the end of the provider's delivery attempt.

Stripe also recommends returning a successful 2xx response quickly, before complex business work that could time out. That is a useful boundary: verify the request, persist what you need, acknowledge it, and do the heavier work separately.

What provider retries do not solve

A naive endpoint can acknowledge a request before it has durably recorded responsibility. If work then fails, the provider may stop retrying while your application has no reliable record from which to recover. In a store-first architecture, durable capture happens before acknowledgement. Asynchronous business or delivery work can still fail after acknowledgement, but the durable Event and its responsibility record make recovery possible.

Retries also do not remove duplicates. A retry can arrive after a response was sent but before the provider observed it, and a manual resend can intentionally deliver the same Event again. Your consumer still needs durable identity and idempotent state transitions.

Provider retry versus application recovery

These are related but different mechanisms:

• Provider retry: Stripe tries to reach your HTTP endpoint again after a failed protocol-level delivery.
• Application recovery: your system finds accepted Events whose downstream work is pending, failed, or ambiguous, then retries or reconciles them.

A useful design records the Event before acknowledging it, keeps attempt history, and makes recovery independent of the original request process. That remains useful even when Stripe's own retries are working exactly as documented.

Where Webhook Handoff fits

Webhook Handoff is a reliability boundary between a supported provider and your application. It verifies and captures an accepted Event, acknowledges the provider-facing request, then attempts delivery asynchronously with history, retries, and controlled replay. It does not replace idempotent Destination processing or promise exactly-once delivery.
