Amazon Simple Workflow Service
API Reference (API Version 2012-01-25)

ListWorkflowTypes

Returns information about workflow types in the specified domain. The results may be split into multiple pages that can be retrieved by making the call repeatedly.

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 doesn't 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 is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

Request Syntax

{
   "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 workflow 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 are returned per call. Use nextPageToken to obtain further pages of results. If maximumPageSize is not set, the default page size is 1,000. You can specify a maximumPageSize size up to 100.

Note

If maximumPageSize is set, the maximum is 100. For instance, if you specify 500, it will return only 100.

Type: Integer

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

Required: No

name

If specified, lists the workflow type with 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 workflow 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 of the name of the workflow types.

Type: Boolean

Required: No

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

Type: String

Length Constraints: Maximum length of 2048.

typeInfos

The list of workflow type information.

Type: Array of WorkflowTypeInfo objects

Errors

OperationNotPermittedFault

Returned when the caller doesn't have sufficient permissions to invoke the action.

HTTP Status Code: 400
