# Receipt Upload

## Create a new receipt upload

 - [POST /v1/expenses/card/{expense_id}/receipt_upload](https://developer.brex.com/openapi/expenses_api/receipt-upload/receiptupload.md): The uri will be a pre-signed S3 URL allowing you to upload the receipt securely. This URL can only be used for a PUT operation and expires 30 minutes after its creation. Once your upload is complete, we will try to match the receipt with existing expenses.

Refer to these docs on how to upload to this pre-signed S3 URL. We highly recommend using one of AWS SDKs if they're available for your language to upload these files.
