// Transfers contacts from one agent or queue to another agent or queue at any
// point after a contact is created. You can transfer a contact to another queue by
// providing the flow which orchestrates the contact to the destination queue. This
// gives you more control over contact handling and helps you adhere to the service
// level agreement (SLA) guaranteed to your customers. Note the following
// requirements:
//   - Transfer is supported for only TASK contacts.
//   - Do not use both QueueId and UserId in the same call.
//   - The following flow types are supported: Inbound flow, Transfer to agent
//     flow, and Transfer to queue flow.
//   - The TransferContact API can be called only on active contacts.
//   - A contact cannot be transferred more than 11 times.
