create_activity(
name: Name,
*,
config_overrides: Optional[SFNClientConfig] = None,
tags: Optional[TagList] = None,
encryption_configuration: Optional[EncryptionConfiguration] = None,
) -> CreateActivityOutput
Creates an activity. An activity is a task that you write in any programming language and host on any machine that has access to Step Functions. Activities must poll Step Functions using the GetActivityTask API action and respond using SendTask* API actions. This function lets Step Functions know the existence of your activity and returns an identifier for use in a state machine and when polling from the activity.
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
CreateActivity is an idempotent API. Subsequent requests won’t create a duplicate resource if it was already created. CreateActivity's idempotency check is based on the activity name. If a following request has different tags values, Step Functions will ignore these differences and treat it as an idempotent request of the previous. In this case, tags will not be updated, even if they are different.
Parameters:
-
name(Name) –The name of the activity to create. This name must be unique for your Amazon Web Services account and region.
A name must not contain:
-
white space
-
brackets
< > { } [ ] -
wildcard characters
? * -
special characters
" # % \ ^ | ~ ` $ & , ; : / -
control characters (
U+0000-001F,U+007F-009F,U+FFFE-FFFF) -
surrogates (
U+D800-DFFF) -
invalid characters (
U+10FFFF)
To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.
-
-
tags(Optional[TagList], default:None) –The list of tags to add to a resource.
An array of key-value pairs. For more information, see Using Cost Allocation Tags in the Amazon Web Services Billing and Cost Management User Guide, and Controlling Access Using IAM Tags.
Tags may only contain Unicode letters, digits, white space, or these symbols:
_ . : / = + - @. -
encryption_configuration(Optional[EncryptionConfiguration], default:None) –Settings to configure server-side encryption.
Raises:
-
ActivityAlreadyExists–Activity already exists.
EncryptionConfigurationmay not be updated. -
ActivityLimitExceeded–The maximum number of activities has been reached. Existing activities must be deleted before a new activity can be created.
-
InvalidEncryptionConfiguration–Received when
encryptionConfigurationis specified but various conditions exist which make the configuration invalid. For example, iftypeis set toCUSTOMER_MANAGED_KMS_KEY, butkmsKeyIdis null, orkmsDataKeyReusePeriodSecondsis not between 60 and 900, or the KMS key is not symmetric or inactive. -
InvalidName–The provided name is not valid.
-
KmsAccessDeniedException–Either your KMS key policy or API caller does not have the required permissions.
-
KmsThrottlingException–Received when KMS returns
ThrottlingExceptionfor a KMS call that Step Functions makes on behalf of the caller. -
TooManyTags–You've exceeded the number of tags allowed for a resource. See the Limits Topic in the Step Functions Developer Guide.
-
UnknownServiceError–The service returned an error code this client does not model.
