Amazon Connect handoff supports IAM role access
The Amazon Connect handoff can now access your AWS account through an IAM role secured with an External ID, so no long-lived access keys are shared. IAM role access is the recommended option for new setups. Existing setups that use an IAM user keep working.
You can also forward Amazon Connect queue events to the integration. The queue a chat entered, and when, are then recorded on the conversation as meta variables. This step is optional.
See Initial Amazon Connect configuration for setup steps.
