# Upload a file for an order requirement

> Upload a single file (multipart/form-data) in response to an order requirement on an order that is in
`AWAITING_INFORMATION` status. Call this endpoint once per required file.

Send `fileKey` (matching a `fileKey` from `requiredFiles` on the GET response) and the binary `file`. Its type
must be one of the supported file formats. Fireblocks encrypts each file and uploads it individually to the
underlying provider. The textual response is submitted separately via
`POST /trading/orders/{orderId}/requirement/data`.

Note: These endpoints are currently in beta and might be subject to changes.
