Eventbridge - Use FIFO SQS for deduplication

Question

I need some events to be delivered exactly once, but I have no control of the message processor (so I can‘t make the recipient idempotent).

Is it possible to route events from Eventbridge to a FIFO SQS for deduplication and from the FIFO sqs to the recipient (lambda on other account? Would this achieve exact-once delivery?

Answer 1

Can you set dynamically messageGroupId from the payload content when you set SQS FIFO as a target for your EventBridge rule?

From the current setup I see that it can be only a hardcoded value.
