I was going through some recent history and transactions in a platform and then it crossed my mind that some complaints were being made about unreflected payment and transaction id were being sent to show proof and then these person's later got credited.
But I ask, is it possible to fake a transaction ID and still be undetected?
Can a fake txn ID be detected in any way effectively?

If you have addresses of sender, receiver and a transaction hash (txid), it is enough to check and verify information younget drom either sender or receiver, your trade partner is correct or just a lie.

Transaction hash is on blockchain and it can not be faked as to have a transaction hash, your trade partner have to broadcast it ti the blockchain and wait for confirmations from miners. If transaction is confirmed, it is solid and can not be reverted.
