Create a transaction image upload URL.
From the response, use the upload url to upload a receipt image for the transaction. For example, to upload a JPEG image, use the following curl command. To upload a PNG image, set the content type as image/png.
curl '{upload_url}'
-H 'Content-Type: image/jpeg'
--upload-file {file_name_with_extension}
Note: BILL supports JPG and PNG file formats for transaction images.
See Transactions in the Guides section for more information, sample requests, and responses.
