Container for the parameters to the InvokeEndpointAsync operation. After you deploy a model into production using Amazon SageMaker hosting services, your client applications use this API to get inferences from the model hosted at the specified endpoint in an asynchronous manner.
Inference requests sent to this API are enqueued for asynchronous processing. The processing of the inference request may or may not complete before you receive a response from this API. The response from this API will not contain the result of the inference request but contain information about where you can locate it.
Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.
Calls to InvokeEndpointAsync are authenticated by using Amazon Web Services
Signature Version 4. For information, see Authenticating
Requests (Amazon Web Services Signature Version 4) in the Amazon S3 API Reference.

Properties
| Name | Type | Description | |
|---|---|---|---|
|
|
Accept | System.String |
Gets and sets the property Accept. The desired MIME type of the inference response from the model container. |
|
|
ContentType | System.String |
Gets and sets the property ContentType. The MIME type of the input data in the request body. |
|
|
CustomAttributes | System.String |
Gets and sets the property CustomAttributes. Provides additional information about a request for an inference submitted to a model hosted at an Amazon SageMaker endpoint. The information is an opaque value that is forwarded verbatim. You could use this value, for example, to provide an ID that you can use to track a request or to provide other metadata that a service endpoint was programmed to process. The value must consist of no more than 1024 visible US-ASCII characters as specified in Section 3.3.6. Field Value Components of the Hypertext Transfer Protocol (HTTP/1.1).
The code in your model is responsible for setting or updating any custom attributes
in the response. If your code does not set this value in the response, an empty value
is returned. For example, if a custom attribute represents the trace ID, your model
can prepend the custom attribute with This feature is currently supported in the Amazon Web Services SDKs but not in the Amazon SageMaker Python SDK. |
|
|
EndpointName | System.String |
Gets and sets the property EndpointName. The name of the endpoint that you specified when you created the endpoint using the CreateEndpoint API. |
|
|
InferenceId | System.String |
Gets and sets the property InferenceId. The identifier for the inference request. Amazon SageMaker will generate an identifier for you if none is specified. |
|
|
InputLocation | System.String |
Gets and sets the property InputLocation. The Amazon S3 URI where the inference request payload is stored. |
|
|
InvocationTimeoutSeconds | System.Int32 |
Gets and sets the property InvocationTimeoutSeconds. Maximum amount of time in seconds a request can be processed before it is marked as expired. The default is 15 minutes, or 900 seconds. |
|
|
RequestTTLSeconds | System.Int32 |
Gets and sets the property RequestTTLSeconds. Maximum age in seconds a request can be in the queue before it is marked as expired. The default is 6 hours, or 21,600 seconds. |
