Upload File - Start

Reference

Service:: Azure AI Services

API Version:: 2024-10-21

An intermediate Upload object is created, allowing you to add Parts to it. Currently, an Upload size can be a maximum of 9 GB in total and will expire two hours after being created. After the Upload is completed a File object will be generated, containing all the uploaded parts. This File object can then be used across our platform just like any other file.
