[ aws . events ]



Sends custom events to Amazon EventBridge so that they can be matched to rules.


PutEvents will only process nested JSON up to 1100 levels deep.

--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.


Represents an event to be submitted.

Time -> (timestamp)

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.


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.

Shorthand Syntax:

Time=timestamp,Source=string,Resources=string,string,DetailType=string,Detail=string,EventBusName=string,TraceHeader=string ...

JSON Syntax:

    "Time": timestamp,
    "Source": "string",
    "Resources": ["string", ...],
    "DetailType": "string",
    "Detail": "string",
    "EventBusName": "string",
    "TraceHeader": "string"

--endpoint-id (string)

The URL subdomain of the endpoint. For example, if the URL for Endpoint is, then the EndpointId is abcde.veo .


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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To send a custom event to CloudWatch Events

This example sends a custom event to CloudWatch Events. The event is contained within the putevents.json file:

aws events put-events --entries file://putevents.json

Here are the contents of the putevents.json file:

    "Source": "com.mycompany.myapp",
    "Detail": "{ \"key1\": \"value1\", \"key2\": \"value2\" }",
    "Resources": [
    "DetailType": "myDetailType"
    "Source": "com.mycompany.myapp",
    "Detail": "{ \"key1\": \"value3\", \"key2\": \"value4\" }",
    "Resources": [
    "DetailType": "myDetailType"


FailedEntryCount -> (integer)

The number of failed entries.

Entries -> (list)

The successfully and unsuccessfully ingested events results. If the ingestion was successful, the entry has the event ID in it. Otherwise, you can use the error code and error message to identify the problem with the entry.

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


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

EventId -> (string)

The ID of the event.

ErrorCode -> (string)

The error code that indicates why the event submission failed.

ErrorMessage -> (string)

The error message that explains why the event submission failed.
