API Reference (API Version 2012-01-25)

ListActivityTypes

Returns information about all activities registered in the specified domain that match the specified name and registration status. The result includes information like creation date, current status of the activity, etc. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.

  • Use an Action element to allow or deny permission to call this action.

  • You cannot use an IAM policy to constrain this action's parameters.

If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

Request Syntax

Copy
{ "domain": "string", "maximumPageSize": number, "name": "string", "nextPageToken": "string", "registrationStatus": "string", "reverseOrder": boolean }

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.

domain

The name of the domain in which the activity types have been registered.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

maximumPageSize

The maximum number of results that will be returned per call. nextPageToken can be used to obtain futher pages of results. The default is 1000, which is the maximum allowed page size. You can, however, specify a page size smaller than the maximum.

This is an upper limit only; the actual number of results returned per call may be fewer than the specified maximum.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 1000.

Required: No

name

If specified, only lists the activity types that have this name.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

nextPageToken

If a NextPageToken was returned by a previous call, there are more results available. To retrieve the next page of results, make the call again using the returned token in nextPageToken. Keep all other arguments unchanged.

The configured maximumPageSize determines how many results can be returned in a single call.

Type: String

Length Constraints: Maximum length of 2048.

Required: No

registrationStatus

Specifies the registration status of the activity types to list.

Type: String

Valid Values: REGISTERED | DEPRECATED

Required: Yes

reverseOrder

When set to true, returns the results in reverse order. By default, the results are returned in ascending alphabetical order by name of the activity types.

Type: Boolean

Required: No

Response Syntax

Copy
{ "nextPageToken": "string", "typeInfos": [ { "activityType": { "name": "string", "version": "string" }, "creationDate": number, "deprecationDate": number, "description": "string", "status": "string" } ] }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

nextPageToken

If a NextPageToken was returned by a previous call, there are more results available. To retrieve the next page of results, make the call again using the returned token in nextPageToken. Keep all other arguments unchanged.

The configured maximumPageSize determines how many results can be returned in a single call.

Type: String

Length Constraints: Maximum length of 2048.

typeInfos

List of activity type information.

Type: Array of ActivityTypeInfo objects

Errors

For information about the errors that are common to all actions, see Common Errors.

OperationNotPermittedFault

Returned when the caller does not have sufficient permissions to invoke the action.

HTTP Status Code: 400

UnknownResourceFault

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

HTTP Status Code: 400
