Introduction
The Amazon Interactive Video Service (IVS) API is REST compatible, using a standard HTTP API and an Amazon Web Services EventBridge event stream for responses. JSON is used for both requests and responses, including errors.
The API is an Amazon Web Services regional service. For a list of supported regions and Amazon IVS HTTPS service endpoints, see the Amazon IVS page in the Amazon Web Services General Reference.
All API request parameters and URLs are case sensitive.
For a summary of notable documentation changes in each release, see Document History.
<p> <b>Allowed Header Values</b> </p> <ul> <li> <p> <code> <b>Accept:</b> </code> application/json</p> </li> <li> <p> <code> <b>Accept-Encoding:</b> </code> gzip, deflate</p> </li> <li> <p> <code> <b>Content-Type:</b> </code>application/json</p> </li> </ul> <p> <b>Resources</b> </p> <p>The following resources contain information about your IVS live stream (see <a href="https://docs.aws.amazon.com/ivs/latest/userguide/getting-started.html"> Getting Started with Amazon IVS</a>):</p> <ul> <li> <p>Channel — Stores configuration data related to your live stream. You first create a channel and then use the channel’s stream key to start your live stream. See the Channel endpoints for more information. </p> </li> <li> <p>Stream key — An identifier assigned by Amazon IVS when you create a channel, which is then used to authorize streaming. See the StreamKey endpoints for more information. <i> <b>Treat the stream key like a secret, since it allows anyone to stream to the channel.</b> </i> </p> </li> <li> <p>Playback key pair — Video playback may be restricted using playback-authorization tokens, which use public-key encryption. A playback key pair is the public-private pair of keys used to sign and validate the playback-authorization token. See the PlaybackKeyPair endpoints for more information.</p> </li> <li> <p>Recording configuration — Stores configuration related to recording a live stream and where to store the recorded content. Multiple channels can reference the same recording configuration. See the Recording Configuration endpoints for more information.</p> </li> </ul> <p> <b>Tagging</b> </p> <p>A <i>tag</i> is a metadata label that you assign to an Amazon Web Services resource. A tag comprises a <i>key</i> and a <i>value</i>, both set by you. For example, you might set a tag as <code>topic:nature</code> to label a particular video category. See <a href="https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html">Tagging Amazon Web Services Resources</a> for more information, including restrictions that apply to tags.</p> <p>Tags can help you identify and organize your Amazon Web Services resources. For example, you can use the same tag for different resources to indicate that they are related. You can also use tags to manage access (see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html"> Access Tags</a>). </p> <p>The Amazon IVS API has these tag-related endpoints: <a>TagResource</a>, <a>UntagResource</a>, and <a>ListTagsForResource</a>. The following resources support tagging: Channels, Stream Keys, Playback Key Pairs, and Recording Configurations.</p> <p>At most 50 tags can be applied to a resource. </p> <p> <b>Authentication versus Authorization</b> </p> <p>Note the differences between these concepts:</p> <ul> <li> <p> <i>Authentication</i> is about verifying identity. You need to be authenticated to sign Amazon IVS API requests.</p> </li> <li> <p> <i>Authorization</i> is about granting permissions. You need to be authorized to view <a href="https://docs.aws.amazon.com/ivs/latest/userguide/private-channels.html">Amazon IVS private channels</a>. (Private channels are channels that are enabled for "playback authorization.")</p> </li> </ul> <p> <b>Authentication</b> </p> <p>All Amazon IVS API requests must be authenticated with a signature. The Amazon Web Services Command-Line Interface (CLI) and Amazon IVS Player SDKs take care of signing the underlying API calls for you. However, if your application calls the Amazon IVS API directly, it’s your responsibility to sign the requests.</p> <p>You generate a signature using valid Amazon Web Services credentials that have permission to perform the requested action. For example, you must sign PutMetadata requests with a signature generated from an IAM user account that has the <code>ivs:PutMetadata</code> permission.</p> <p>For more information:</p> <ul> <li> <p>Authentication and generating signatures — See <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html">Authenticating Requests (Amazon Web Services Signature Version 4)</a> in the <i>Amazon Web Services General Reference</i>.</p> </li> <li> <p>Managing Amazon IVS permissions — See <a href="https://docs.aws.amazon.com/ivs/latest/userguide/security-iam.html">Identity and Access Management</a> on the Security page of the <i>Amazon IVS User Guide</i>.</p> </li> </ul> <p> <b>Channel Endpoints</b> </p> <ul> <li> <p> <a>CreateChannel</a> — Creates a new channel and an associated stream key to start streaming.</p> </li> <li> <p> <a>GetChannel</a> — Gets the channel configuration for the specified channel ARN (Amazon Resource Name).</p> </li> <li> <p> <a>BatchGetChannel</a> — Performs <a>GetChannel</a> on multiple ARNs simultaneously.</p> </li> <li> <p> <a>ListChannels</a> — Gets summary information about all channels in your account, in the Amazon Web Services region where the API request is processed.

public CreateRecordingConfigurationResult createRecordingConfiguration(CreateRecordingConfigurationRequest request)
Creates a new recording configuration, used to enable recording to Amazon S3.
Known issue: In the us-east-1 region, if you use the Amazon Web Services CLI to create a recording
configuration, it returns success even if the S3 bucket is in a different region. In this case, the
state
of the recording configuration is CREATE_FAILED
(instead of ACTIVE
).
(In other regions, the CLI correctly returns failure if the bucket is in a different region.)
Workaround: Ensure that your S3 bucket is in the same region as the recording configuration. If you create a recording configuration in a different region as your S3 bucket, delete that recording configuration and create a new one with an S3 bucket from the correct region.

public CreateStreamKeyResult createStreamKey(CreateStreamKeyRequest request)
Creates a stream key, used to initiate a stream, for the specified channel ARN.
Note that CreateChannel creates a stream key. If you subsequently use CreateStreamKey on the same channel, it will fail because a stream key already exists and there is a limit of 1 stream key per channel. To reset the stream key on a channel, use DeleteStreamKey and then CreateStreamKey.

public DeleteChannelResult deleteChannel(DeleteChannelRequest request)
Deletes the specified channel and its associated stream keys.
If you try to delete a live channel, you will get an error (409 ConflictException). To delete a channel that is live, call StopStream, wait for the Amazon EventBridge "Stream End" event (to verify that the stream's state was changed from Live to Offline), then call DeleteChannel.
