Every webhook SIBI sends to your endpoints is recorded. The
**[SIBI Developer Portal](https://developer.sibipro.com/webhooks)** shows those records: which events were sent, what
your server returned for each attempt, and the exact payload we posted. You can also re-send any delivery from there.

> **Delivery records are kept for 90 days**
>
> A delivery and its attempts are deleted 90 days after it was first sent. See [Data retention](#data-retention) for
> what is stored, and for the size limits on payloads and response bodies.

## Webhooks

**[The Webhooks page](https://developer.sibipro.com/webhooks)** lists every webhook configured for your organization:

| Column | Meaning |
| --- | --- |
| URL | The endpoint SIBI posts to |
| Topics | The topics this webhook is filtered to. `All topics` means it receives every topic |
| Env | `Prod` for webhooks fed by the production API, `Test` for webhooks fed by the [test environment](/rest/test-environment) |
| Status | `Enabled` webhooks receive events; `Disabled` ones do not. Events that fire while a webhook is disabled are not recorded as deliveries — see [Disabling a webhook](/events/receive-events#disabling-a-webhook) |
| Created at | When the webhook was registered |

Selecting a row opens that webhook's deliveries. **Register a webhook** adds one, and **Delete** on a webhook's page
removes it — see [Receive Events](/events/receive-events). An organization can have 5 webhooks at a time.

## Deliveries

A **delivery** is one event sent to one webhook. It holds the payload, the outcome, and every attempt SIBI made,
including the attempts from a redrive.

Only events sent to an enabled webhook produce a delivery. While a webhook is disabled, matching events are skipped
outright — no delivery is recorded, and re-enabling the webhook does not backfill them.

The deliveries list shows, newest first:

| Column | Meaning |
| --- | --- |
| Delivered at | When SIBI first sent the event |
| Topic | The event topic, e.g. `order.created` |
| Outcome | `Succeeded` if an attempt returned a 2xx status, `Errored` if all attempts failed |
| Attempts | How many attempts the delivery has |
| Last response | The status of the most recent attempt, e.g. `HTTP 500`, or the connection error |
| Duration | How long the most recent attempt took |

A delivery that has been re-sent also carries a **Re-sent** badge with the time of the last redrive.

### Filter and search

- **Outcome** narrows the list to `Succeeded` or `Errored` deliveries.
- **Search payloads** does a full-text search of the stored payloads, scoped to this webhook. Search for an
  identifier that appears in the body — a PO number, an order id, an invoice id — to find the delivery that carried it.
  Punctuation inside an identifier is ignored, so `PO-123` and `po123` match the same delivery.
- **Refresh** re-reads the list, and **Load more** pages further back in time.

Both the filters and the search only see deliveries inside the 90-day retention window.

## Delivery details

Selecting a delivery opens it. The page has three sections.

**Summary** — the delivery id, the endpoint the payload was sent to, and, when SIBI has them, the event id and the id of
the resource the event is about (for example the order id).

**Attempts** — one row per attempt, in order:

| Column | Meaning |
| --- | --- |
| Attempt | The attempt number. Redriven attempts continue the same numbering |
| Started at | When the request was sent |
| Result | The HTTP status your server returned, or `Request failed` when the request never completed |
| Duration | How long the request took |
| Response | The response body your server returned |

SIBI stores the response body only for failed attempts — for a 2xx the row reads
`Response body not stored for non-error response`. When the request never got a response at all, the connection error is
stored in its place.

**Payload** — the exact JSON body SIBI posted, pretty-printed, with a **Copy payload** button. This is the body your
signature was computed over.

## Redriving a delivery

**Redrive** re-sends a delivery's payload to the webhook's current URL, signed with the webhook's current signing
secret. Use it after you have fixed the endpoint that rejected the event, or after your service was down.

- The payload is unchanged — the redrive sends what was originally sent, not a fresh snapshot of the resource.
- The new attempts are appended to the same delivery, continuing its attempt numbering, and the delivery's outcome is
  updated to reflect them.
- A redrive follows the same [retry policy](/events/receive-events#status-code-retry-policy) as an original send, so it
  can take a while to finish. The delivery shows `Redrive queued` until the attempt lands, then refreshes on its own.
- Redrive is unavailable while a redrive of that delivery is already running, or on a disabled webhook.
- A delivery whose payload was too large to store cannot be re-driven.

> **Warning**
>
> Your endpoint must be idempotent. A redrive re-delivers an event your server may have already processed.
>
> Redriving the non-latest delivery for a particular resource could inaccurately reflect the current state of that resource.

## Data retention

Deliveries, their attempts, the response bodies, and the payloads are all deleted 90 days after the delivery was first
sent.

- **Payloads over 200 KB are not stored.** The delivery still records its attempts and outcome, and the payload section
  reads `The payload was larger than 200 KB and was not stored with this delivery.` A delivery with no stored payload
  cannot be found by payload search and cannot be redriven. This limit only applies to what is recorded, the full payload is always sent.

- **Response bodies are stored only for failed attempts, truncated at 8 KB.** We log the status code for attempts that returned a 2xx, but discard the body. Connection errors are stored in place of a body, under the same 8 KB limit. A
  truncated body is shown with a trailing `…`.

Redriving a delivery does not extend its retention. The 90 days run from the original send, so a delivery near the end
of its window will expire whether or not it has been re-sent.
