The approval service provides features for managing and tracking the human approval tasks associated with a service process/artifact in a provider realm. It also provides a record of the approval process when it completes.

The following samples will help in creating new approval policy.

• Get approval policy types
• Define and create approval policy

A typical payload to create a basic approval policy for policy type "Service Catalog - Catalog Item Request" will look like below:

POST https://{{va-fqdn}}/approval-service/api/policies

 "description": "",

The following samples will help perform approval actions programmatically.

• Get approval work items
• Get approval request information
• Approve a request
• Reject a request

A basic approve request payload will look like as below:

POST https://{{va-fqdn}}/workitem-service/api/workitems/{{work-item-guid}}/actions/com.vmware.csp.core.approval.action.approve

{
  "workItemId": "{{work-item-guid}}",
  "workItemActionId": "com.vmware.csp.core.approval.action.approve",
  "formData": {
    "entries": [
    	{
			"key": "source-source-provider-Cafe.Shim.VirtualMachine.NumberOfInstances",
			"value": {
				"type": "integer",
				"value": 1
			}
    	},
    	{
			"key": "source-source-provider-VirtualMachine.Memory.Size",
			"value": {
				"type": "integer",
				"value": 512
			}
    	},
    	{
			"key": "source-source-provider-VirtualMachine.CPU.Count",
			"value": {
				"type": "integer",
				"value": 1
			}
    	},
    	{

		},
    	{
