Each Monero transaction has an identity number or code linked to it.

This is a code used to track the transaction and ensure that it has completed successfully.

Each transaction needs to be mined before it can show up in the recipient account. Monero transactions require a minimum of 10 confirmations before they can be considered completed.

You can use the transaction ID to check if the transaction has been mined successfully, by visiting https://xmrchain.net/ and typing in the transaction ID.

You will be checking to see that the transaction has a "Block" number and how many confirmations it has.
