InputPathsMap (dict) --
Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.
InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.
The keys cannot start with "AWS."
InputTemplate (string) --
Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value > The InputTemplate must be valid JSON.
If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

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.
The time stamp of the event, per RFC3339 . If no time stamp is provided, the time stamp of the PutEvents call is used.
The source of the event. This field is required.
AWS resources, identified by Amazon Resource Name (ARN), which the event primarily concerns. Any number, including zero, may be present.
Free-form string used to decide what fields to expect in the event detail.
A valid JSON string. There is no other schema imposed. The JSON string may contain fields and nested subobjects.

Running PutPermission permits the specified AWS account to put events to your account's default event bus . CloudWatch Events rules in your account are triggered by these events arriving to your default event bus.
For another account to send events to your account, that external account must have a CloudWatch Events rule with your account's default event bus as a target.
To enable multiple AWS accounts to put events to your default event bus, run PutPermission once for each of these accounts.
The permission policy on the default event bus cannot exceed 10 KB in size.

Request Syntax
response = client.put_permission(
Action='string',
Principal='string',
StatementId='string'
)
[REQUIRED]
The action that you are enabling the other account to perform. Currently, this must be events:PutEvents .
[REQUIRED]
The 12-digit AWS account ID that you are permitting to put events to your default event bus. Specify "*" to permit any account to put events to your default event bus.
If you specify "*", avoid creating rules that may match undesirable events. To create more secure rules, make sure that the event pattern for each rule contains an account field with a specific account ID from which to receive events. Rules with an account field do not match any events sent from other accounts.
[REQUIRED]
An identifier string for the external account that you are granting permissions to. If you later want to revoke the permission for this external account, specify this StatementId when you run RemovePermission .
None
Creates or updates the specified rule. Rules are enabled by default, or based on value of the state. You can disable a rule using DisableRule .
If you are updating an existing rule, the rule is replaced with what you specify in this PutRule command. If you omit arguments in PutRule , the old values for those arguments are not kept. Instead, they are replaced with null values.
When you create or update a rule, incoming events might not immediately start matching to new or updated rules. Allow a short period of time for changes to take effect.
A rule must contain at least an EventPattern or ScheduleExpression. Rules with EventPatterns are triggered when a matching event is observed. Rules with ScheduleExpressions self-trigger based on the given schedule. A rule can have both an EventPattern and a ScheduleExpression, in which case the rule triggers on matching events as well as on a schedule.
Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, CloudWatch Events uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.

Response Structure
(dict) --
RuleArn (string) --
The Amazon Resource Name (ARN) of the rule.
Adds the specified targets to the specified rule, or updates the targets if they are already associated with the rule.
Targets are the resources that are invoked when a rule is triggered.
You can configure the following as targets for CloudWatch Events:
Creating rules with built-in targets is supported only in the AWS Management Console. The built-in targets are EC2 CreateSnapshot API call , EC2 RebootInstances API call , EC2 StopInstances API call , and EC2 TerminateInstances API call .
For some target types, PutTargets provides target-specific parameters. If the target is a Kinesis data stream, you can optionally specify which shard the event goes to by using the KinesisParameters argument. To invoke a command on multiple EC2 instances with one rule, you can use the RunCommandParameters field.
To be able to make API calls against the resources that you own, Amazon CloudWatch Events needs the appropriate permissions. For AWS Lambda and Amazon SNS resources, CloudWatch Events relies on resource-based policies. For EC2 instances, Kinesis data streams, and AWS Step Functions state machines, CloudWatch Events relies on IAM roles that you specify in the RoleARN argument in PutTargets . For more information, see Authentication and Access Control in the Amazon CloudWatch Events User Guide .
If another AWS account is in the same region and has granted you permission (using PutPermission ), you can send events to that account. Set that account's event bus as a target of the rules in your account. To send the matched events to the other account, specify that account's event bus as the Arn value when you run PutTargets . If your account sends events to another account, your account is charged for each sent event. Each event sent to another account is charged as a custom event. The account receiving the event is not charged. For more information, see Amazon CloudWatch Pricing .
For more information about enabling cross-account events, see PutPermission .
Input , InputPath , and InputTransformer are mutually exclusive and optional parameters of a target. When a rule is triggered due to a matched event:
When you specify InputPath or InputTransformer , you must use JSON dot notation, not bracket notation.
When you add targets to a rule and the associated rule triggers soon after, new or updated targets might not be immediately invoked. Allow a short period of time for changes to take effect.
This action can partially fail if too many requests are made at the same time. If that happens, FailedEntryCount is non-zero in the response and each entry in FailedEntries provides the ID of the failed target and the error code.

Tests whether the specified event pattern matches the provided event.
Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, CloudWatch Events uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.
