Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

MaxResults

The maximum number of scheduled action results. This value can be between 1 and 50. The default value is 50.

If this parameter is used, the operation returns up to MaxResults results at a time, along with a NextToken value. To get the next set of results, include the NextToken value in a subsequent call. If this parameter is not used, the operation returns up to 50 results and a NextToken value, if applicable.

Type: Integer

Required: No

NextToken

The token for the next set of results.

Type: String

Required: No

Examples

If you plan to create requests manually, you must replace the Authorization header contents in the examples (AUTHPARAMS) with a signature. For more information, see Signing AWS API requests in the IAM User Guide. If you plan to use the AWS CLI or one of the AWS SDKs, these tools sign the requests for you.

Example

The following example describes the scheduled actions for the dynamodb service namespace.
