# File links & expiry

> File URLs returned by Dojah (selfies, documents) are temporary and expire within about an hour — copy them to your own storage.

When a response or webhook includes a file — a selfie, an ID image, a document scan — it’s a temporary URL, not permanent storage. Save it before it expires.

## Links are short-lived

File URLs Dojah returns expire within about **one hour**. After that the link stops working and the file is no longer reachable from it.

## What to do

* **Download immediately.** When you receive a file URL, fetch the file and store it in your own system right away.
* **Don’t persist the URL.** Saving the link instead of the file means a broken reference within the hour.
* **Re-fetch if needed.** If you only have the verification reference, call the endpoint again to get a fresh link.

<Warning>
  **Applies to webhooks too.** File URLs inside [webhook](/api-reference/core-concepts/webhooks-signatures) payloads expire on the same schedule — copy them as soon as the event arrives.
