An activity is a task that you write in any programming language and host on any machine that has access to AWS Step Functions .

Activities must poll Step Functions using the GetActivityTask API action and respond using SendTask* API actions. This function makes Step Functions aware of your activity and returns an identifier for use in a state machine and when polling from the activity.

For information about creating an activity, see Creating an Activity State Machine in the AWS Step Functions Developer Guide and CreateActivity in the AWS Step Functions API Reference .

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.stepfunctions.*;
 CfnActivity cfnActivity = CfnActivity.Builder.create(this, "MyCfnActivity")
         .name("name")
         // the properties below are optional
         .encryptionConfiguration(EncryptionConfigurationProperty.builder()
                 .type("type")
                 // the properties below are optional
                 .kmsDataKeyReusePeriodSeconds(123)
                 .kmsKeyId("kmsKeyId")
                 .build())
         .tags(List.of(TagsEntryProperty.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();
