How to Transfer a Contact to Another Queue Using Amazon Connect API?

1. Your main contact flow is responsible for handling incoming contacts in "Queue1". To facilitate transfers, this flow should include logic to check for the presence of the TransferContactFlow attribute in a contact's attributes.

   Add the TransferContactFlow attribute to the contacts you wish to transfer from "Queue1" to another queue.

2. Use the UpdateContactAttributes API to assign the TransferContactFlow attribute to a contact. The value of this attribute should be the ARN of the transfer contact flow, which directs the contact to "Queue2".

   The main contact flow will monitor the TransferContactFlow attribute of each contact. Contacts with this attribute will be transferred to the queue associated with the specified ARN in the attribute.

3. When a contact possesses the TransferContactFlow attribute, the main contact flow should execute a transfer to the flow indicated by this attribute. This is typically achieved using a "Check Contact Attributes" block, followed by a "Transfer to Flow" block within the contact flow.

4. If necessary, you can incorporate an AWS Lambda function into your contact flow for additional logic or integration with external systems, either before or after the contact transfer.
