After generating the secure upload URL in Step 1, you must upload the file directly to the provided Amazon S3 storage URL.

This step does not use the Panda Video API directly. Instead, the file must be sent to the pre-signed URL returned by the Generate_file_upload_url endpoint.

The upload request must:

Use the pre-signed URL returned in Generate_file_upload
Be associated with the same assistant_id used when generating the upload URL
Send the file in binary format
Match exactly the file_size informed in the first request

If the uploaded file size does not match the value provided during URL generation, the upload may fail.

Name	Type	Description
assistant_id	string (UUID)	The unique identifier of the Tutor AI assistant. Must be the same assistant_id used in Generate_file_upload when generating the upload URL.
upload_url	string	The pre-signed S3 URL returned by the Generate File Upload URL endpoint. This URL must be used to perform the PUT request that uploads the file in binary format.
