Returns information about the specified workflow type. This includes configuration settings specified when the type was registered and other information such as creation date, current status, etc.
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. - Constrain the following parameters by using a
Condition
element with the appropriate keys.workflowType.name
: String constraint. The key isswf:workflowType.name
.workflowType.version
: String constraint. The key isswf:workflowType.version
.
If the caller does not have sufficient permissions to invoke the action, or the parameter
values fall outside the specified constraints, the action fails by throwing
OperationNotPermitted
. For details and example IAM policies, see Using IAM to
Manage Access to Amazon SWF Workflows.

Examples
Workflow Type CRUD.
Shows an example of workflow type CRUD methods.
This sample uses anonymous functions, which are only available in PHP 5.3+. For PHP 5.2 users, you must used named functions instead of anonymous ones.
