1. API Description

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

This API is used to request concurrency quota. The timeout period of the API is 20 seconds.

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.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name Required Type Description
Action Yes String Common Params. The value used for this API: ApplyConcurrent.
Version Yes String Common Params. The value used for this API: 2022-01-10.
Region No String Common Params. This parameter is not required for this API.
UserId Yes String Unique user ID, which is customized by you and is not parsed by CAR. Based on your needs, you can either define unique IDs for users or use timestamps to generate random IDs. Make sure the same ID is used when a user reconnects to your application.
UserIp Yes String Public IP address of the user's client, which is used for nearby scheduling.
ProjectId Yes String Project ID.
ApplicationVersionId No String Application version ID. If the application of the current version is requested, you do not need to fill in this field. If the application of the other versions is requested, you need to specify the version through this field.
ApplicationId No String Application ID, which is used only by the multi-application project to specify applications. For a single-application project, this parameter is ignored, and the application bound to the project will be used.

3. Output Parameters

Parameter Name Type Description
RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
