Create Upload
<b>Deprecated.</b> This endpoint is deprecated in favor of the [Create Bulk Transactions Upload URL](/2024-10-01/api/transactions/create-bulk-transactions-upload-url) endpoint. New integrations should use the bulk flow outlined in the [Historical Transaction Uploads](/2024-10-01/api/integration-guides/historical-transaction-uploads) integration guide.
Call this endpoint to create an upload session and retrieve an upload ID. Using the upload ID in the [Add Upload Part](/2024-10-01/api/transactions/uploads/create-part) endpoint, historical transactions can be sent in batches for further processing.
<b>Required scopes:</b> `transaction:write`
