Cloud Recording RESTful API

Agora Cloud Recording is a component provided by Agora to record and save voice calls, video calls, and interactive streaming. You can send HTTP requests from your business server to the Agora server to manage Cloud Recording tasks on the server side.

To monitor the status of your cloud recording, Agora provides the message notification service. After enabling this service, you receive events related to cloud recording through a webhook.

Since Agora dynamically adjusts the IP addresses of the message notification server, best practice is to regularly query the IP addresses and update the firewall whitelist configuration to continue receiving cloud recording notifications.

Base URL

https://api.sd-rtn.com

Authentication

When sending an HTTP request, use Basic HTTP authentication and fill in the Authorization field in the HTTP request header with the generated credentials. For details on generating the Authorization field, see Authenticate REST calls.

Endpoints

The RESTful API includes the following set of endpoints for managing the cloud recording functionality:

acquire: Request a resource ID for cloud recording.
start: Call this method within two seconds after getting the resource ID to start cloud recording. During recording, call query, update, and updateLayout methods as needed.
query: Check the status of cloud recording.
update: Update recording settings.
updateLayout: Update the video mixing layout.
stop: To end a recording, call stop to leave the channel and stop the recording.

`acquire`

Get a cloud recording resource ID.

POST /v1/apps/{appid}/cloud_recording/acquire

Before starting cloud recording, call the acquire method to get a resource ID. One resource ID can be used for only one recording session.

Note: To ensure success when starting cloud recording, proceed as follows:

Call acquire and start requests in pairs.
start cloud recording within two seconds of receiving the resource ID from each acquire request. Batch fetching of resource IDs followed by batch start requests may lead to request failure.
The resource ID is valid for five minutes and should be used as soon as possible.

Response

status	Description	Schema
200 OK	If the returned HTTP status code is `200`, the request is successful. If you set the `startParameter` object in the request body and its value is invalid, it will not affect the success of the `acquire` request, but you will receive an error in the subsequent `start` request.	acquire-response

`start`

Start cloud recording.

POST /v1/apps/{appid}/cloud_recording/resourceid/{resourceid}/mode/{mode}/start

After receiving a cloud recording resource ID using the acquire method, call the start method to start cloud recording.

`get-ncs-ip`

Query the IP addresses of the message notification server.

GET /v1/ncs/ip

Query the IP address or IP address list of the message notification server.

After you enable the message notification service, the Agora message notification service can notify your server of events that occur during a cloud recording with HTTPS requests. Agora dynamically adjusts the IP addresses of the message notification server every 24 hours. Query the IP addresses using this method. After the query, add the IP address (or IP address list) to the whitelist.

info

Best practice is to query the IP addresses at least once every 24 hours and automatically update the firewall configuration to avoid interruption in the reception of notifications.

Name	Type	Required	Description
`token`	String	false	A dynamic key used for authentication. If your project has enabled the App certificate, pass in the dynamic key of your project in this field. See Token Authentication for details. Note: You only need to set the authentication token in individual recording and composite recording modes. Cloud recording service does not support updating tokens currently. To ensure normal recording, ensure that the effective duration of the token is longer than your expected recording time, to avoid the token expiring and causing the recording task to exit the channel and end the recording.
`storageConfig`	storageConfig	true	Configuration for third-party cloud storage.
`recordingConfig`	recordingConfig	false	Configuration for recorded audio and video streams. Note: You only need to set this field in individual recording and composite recording modes.
`recordingFileConfig`	recordingFileConfig	false	Configuration for recorded files. Note: This field cannot be set when only taking screenshots, but it needs to be set in all other cases. Other cases include the following: Recording without transcoding, recording with transcoding, or recording and taking screenshots simultaneously in individual recording mode. Composite recording. In the web page recording mode, you can do page recording only, or simultaneously do the page recording and push it to the CDN.
`snapshotConfig`	snapshotConfig	false	Configurations for screenshot capture. Note: Only need to set this field when using the screenshot function in individual recording mode. Screenshot usage instructions: - The screenshot function is only applicable to individual recording mode (`individual`). - You can either take screenshots in an individual recording process, or record and take screenshots at the same time. For more information, see Capture Screenshots. The scenario of simultaneous recording and screenshot capture requires setting the `recordingFileConfig` field. - If the recording service or recording upload service is abnormal, the screenshot will fail. Recording is not affected when there is a screenshot exception. - `streamTypes` must be set as 1 or 2 when capturing screenshots. If you have set `subscribeAudioUid`, you must also set `subscribeVideoUids`.
`extensionServiceConfig`	extensionServiceConfig	false	Configurations for extended services. Note: Only need to set in web page recording mode.
`appsCollection`	appsCollection	false	Application configurations Note: This setting is only required when in individual recording mode and when postponed transcoding or audio mixing is enabled.
`transcodeOptions`	transcodeOptions	false	Configurations for the recorded files generated under postponed transcoding or audio mixing. Note: This setting is only required when in individual recording mode and when postponed transcoding or audio mixing is enabled.

Name	Type	Required	Description

Note: To ensure the success rate and real-time performance of the upload of the recording file, the region of the third-party cloud storage must be the same as the `region` of the application server where you initiate the request. For example: If the App server from which you initiate the request is in mainland China, and meanwhile the third-party cloud storage needs to be set to a region within mainland China. See Third-party Cloud Storage regions.
`bucket`	String	true	Third-party cloud storage bucket. The bucket name needs to comply with the naming rules of the corresponding third-party cloud storage service.
