Request body parameters

Pass in the following parameters in the request body.

Parameter Type Description

Parameter	Type	Description
`mode`	String	(Optional) The recording mode: Set this parameter as `web` to enable web page recording mode. The format of recorded files is MP4. When the length of the recorded file reaches around two hours, or when the size of the file exceeds around 2 GB, the recording service automatically creates another MP4 file. If you do not set this parameter, Flexible Classroom records the audio and video of the teachers in composite recording mode by default. The format of recorded files is M3U8 and TS.
`webRecordConfig`	Object	(Optional) When the `mode` is set as `web`, you need to set the detailed configuration of the web page recording through `webRecordConfig`, including the following fields: `rootUrl`: (Required) String, the root address of the web page to be recorded. During the recording, Agora Edu Cloud Service automatically gets the full address of the web page to be recorded by putting `rootUrl`, `roomUuid`, `roomType`, and other parameters together. If you set both `url` and `rootUrl`, `url` overrides `rootUrl`. `publishRtmp`: (Optional) Whether to push the recorded webpage to CDN: `true`: Yes. `false`: No. `onhold`: (Required) Boolean. You can set this parameter as: `true`: Pauses recording immediately after the web page recording task is enabled. The recording service opens and renders the web page to be recorded, but does not generate a slice file. `false`: (Default) Enables the web page recording task and starts recording. `videoBitrate`: (Optional) Number. The bitrate of the video (Kbps). The value range is [50, 8000]. The default value of `videoBitrate` varies according to the resolution of the output video: If the resolution of the output video is less than 1280 × 720, the default value of `videoBitrate` is 1500. If the resolution of the output video is greater than or equal to 1280 × 720, the default value of `videoBitrate` is 2000. `videoFps`: (Optional) Number. The frame rate of the video (fps). The value range is [5, 60]. The default value is 15. `audioProfile`: (Optional) Number. The sample rate, encoding mode, number of audio channels, and bitrate. 0: (Default) Sample rate of 48 kHz, music encoding, mono, and a bitrate of up to 48 Kbps. 1: Sample rate of 48 kHz, music encoding, mono, and a bitrate of up to 128 Kbps. 2: Sample rate of 48 kHz, music encoding, stereo, and a bitrate of up to 192 Kbps. `videoWidth`: Number. The width of the video (pixels). The value range is [480, 1280]. The default value is 1280. The product of `videoWidth` and `videoHeight` should not exceed 921,600 (1280 × 720). `videoHeight`: Number. The height of the video (pixels). The value range is [480, 1280]. The default value is 720. The product of `videoWidth` and `videoHeight` should not exceed 921,600 (1280 × 720). `maxRecordingHour`: Number, the maximum recording length (hours). The value range is [1,720]. If you set the class duration, Agora Edu Cloud Service gets the maximum recording length by rounding up the class duration. For example, if the class duration is 1800 seconds, `maxRecordingHour` is one hour. If you do not set the class duration, the default value of `maxRecordingHour` is two hours. If the limit set by `maxRecordingHour` is exceeded, the recording stops automatically.
`retryTimeout`	Number	The amount of time (seconds) that the Flexible Classroom cloud service waits between tries. The Flexible Classroom cloud service reties twice at most.

Ensure service reliability

This section presents the overall strategy you use to ensure high availability of REST services.

Switch the domain name

To ensure high availability of REST services, Agora enables you to switch domain names when you experience service outage due to regional network failures. Take the following steps to set up and switch your domain name:

Set the primary domain name based on the location of your service server:
- If the DNS address of the service server is located in a country or region other than mainland China, set the primary domain name to api.agora.io.
- If the DNS address of the service server is in mainland China, set the primary domain name to api.sd-rtn.com.
If your attempt to initiate a RESTful API request using the primary domain fails, set up your retry strategy as follows:
1. Primary domain retry: Retry using the same primary domain name.
2. Alternate domain retry:
  - If the current primary domain name is api.sd-rtn.com, use api.agora.io as the alternate domain name.
  - If the current primary domain name is api.agora.io, use api.sd-rtn.com as the alternate domain name.
3. Adjacent domain retry: If alternate domain retry fails, retry using the domain name adjacent to the current region.
  
  For example, suppose your business server is located in Europe. You set the primary domain name to api.agora.io, and the business server resolves the primary domain name to Germany. Germany is located in central Europe (api-eu-central-1.agora.io). The domain name table shows that the adjacent area is West Europe. Use the api-eu-west-1.agora.io or api-eu-west-1.sd-rtn.com domain name to retry.

Precautions

Take the following precautions when setting up your retry strategy:

To avoid exceeding the QPS limit with retry requests, best practice is to use a back-off strategy. For example, wait 1 second before you retry for the first time, wait 3 seconds before retrying the second time, and wait 6 seconds before retry a third time.
If the request fails because of a network problem rather than a DNS domain name resolution problem, skip alternate domain retry and proceed to adjacent domain retry.
Before switching to the region domain name, ensure that the REST services you wish to use, for example, cloud recording or channel management, are deployed in that region.

Domain name table

The following table shows the primary and region domain names for various regions.

Primary domain name	Region domain name	Region
`api.sd-rtn.com`	`api-us-west-1.sd-rtn.com`	Western United States
	`api-us-east-1.sd-rtn.com`	Eastern United States
