Request Syntax

response = client.put_events(
            'Time': datetime(2015, 1, 1),
            'Source': 'string',
            'Resources': [
            'DetailType': 'string',
            'Detail': 'string',
            'EventBusName': 'string',
            'TraceHeader': 'string'
  • Entries (list) –


    The entry that defines an event in your system. You can specify several parameters for the entry such as the source and type of the event, resources associated with the event, and so on.

    • (dict) –

      Represents an event to be submitted.

      • Time (datetime) –

        The time stamp of the event, per RFC3339. If no time stamp is provided, the time stamp of the PutEvents call is used.

      • Source (string) –

        The source of the event.

      • Resources (list) –

        Amazon Web Services resources, identified by Amazon Resource Name (ARN), which the event primarily concerns. Any number, including zero, may be present.

        • (string) –

      • DetailType (string) –

        Free-form string, with a maximum of 128 characters, used to decide what fields to expect in the event detail.

      • Detail (string) –

        A valid JSON object. There is no other schema imposed. The JSON object may contain fields and nested subobjects.

      • EventBusName (string) –

        The name or ARN of the event bus to receive the event. Only the rules that are associated with this event bus are used to match the event. If you omit this, the default event bus is used.


        If you’re using a global endpoint with a custom bus, you must enter the name, not the ARN, of the event bus in either the primary or secondary Region here and the corresponding event bus in the other Region will be determined based on the endpoint referenced by the EndpointId.

      • TraceHeader (string) –

        An X-Ray trace header, which is an http header (X-Amzn-Trace-Id) that contains the trace-id associated with the event.

        To learn more about X-Ray trace headers, see Tracing header in the X-Ray Developer Guide.

  • EndpointId (string) –

    The URL subdomain of the endpoint. For example, if the URL for Endpoint is https://abcde.veo.endpoints.event.amazonaws.com, then the EndpointId is abcde.veo.


    When using Java, you must include auth-crt on the class path.

      For each record, the index of the response element is the same as the index in the request array.

      • (dict) –

        Represents an event that failed to be submitted. For information about the errors that are common to all actions, see Common Errors.
