1. API Description

Domain name for API request: vod.intl.tencentcloudapi.com.

  • We strongly recommend that you use the server-side upload SDK provided by VOD to upload files. Directly invoking the API for upload is significantly more difficult and involves a much larger workload than using the SDK.
    This API is used to apply for uploading media files (and cover files), obtain the meta information for uploading files to VOD (including upload path and upload signature), and is used for subsequent upload APIs.
    For the upload process, see Server-Side Upload Overview.

A maximum of 100 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
