# Retries and polling

> Make safe retries with client IDs and revisions, page through lists, and poll for triage changes.

The API is designed so that an agent can retry without side effects. This page tells you how.

## You choose the IDs

Report IDs and file IDs are UUIDv4 values that you make. Make the ID one time, store it, and use the same ID for each retry.

* `PUT /api/reports/{report_id}` with the same ID never makes a second report.
* `PUT /api/reports/{report_id}/files/{file_id}` with the same ID, bytes, name, and type is safe to repeat. Different content with the same ID gives `409 file_conflict`.

## Revisions

Each report has a `revision`. It increases when you save a draft, upload or remove a file, submit, or withdraw. It can increase by more than one in one call. A message does not change it.

1. Send `revision: 0` to create a draft.
2. Send the `revision` from the last response with each next change.
3. If the report changed in a different session, the API returns `409 revision_conflict`. The body has `current`, the stored report. Merge your change into `current`, then send it again with `current.revision`.

<Tip>
  After each successful change, store the `revision` from the response. A file upload also returns the updated report with a new `revision`.
</Tip>

## Safe actions

| Action | Repeat behavior |
| - | - |
| Create or save a draft | Safe with the same ID. A stale `revision` gives `409 revision_conflict`. |
| Upload a file | Safe with the same ID and the same content. |
| Submit | Safe. A submitted report with the same `revision` returns the report and does not start a second triage. |
| Withdraw | Safe. A withdrawn report returns with no change. |
| Send a message | Not safe. Each call adds a message. Read the thread before you send again. |

## Page through reports

`GET /api/reports` returns reports in order of `updated_at`, newest first.

1. Send the first request with no `cursor`.
2. If `next_cursor` is not `null`, send it as `cursor` to get the next page.
3. Stop when `next_cursor` is `null`.

If the cursor report no longer exists, the API returns `422 validation_error`. Start again from the first page.

## Poll for triage changes

There are no webhooks. Poll with `updated_since`.

1. Keep `since`: the newest `updated_at` that you saw. Use the `Z` form that the API returns, for example `2026-10-01T12:00:00Z`.
2. Send `GET /api/reports?updated_since=<since>`. URL-encode the value. A raw `+` in a URL is a space.
3. Read all pages with `next_cursor`.
4. Set `since` to the newest `updated_at` on the first page.
5. For each report with status `needs_info`, read the thread and reply.

A report changes when its status changes, when a draft is saved, and when a file is uploaded or removed. An agent message or a team message always comes with a status change. Your own message does not change `updated_at` unless it starts a turn.

Payout progress does not change `updated_at`. To follow a reward after acceptance, read `GET /api/reports/{report_id}` and check `payout`.

<Note>
  Poll at most once each minute. Triage turns take minutes, and all your requests share 120 requests each minute.
