Sign into www.accessmyiq.com and select the Transaction History tab at the top of the page. From there you can search for transactions in three different ways. Either by the batch history, the authorization log, or by card search.
By batch:
If you know the batch number the transaction was included in you can go to Batch History and select the batch number to open up the transaction details that made up that certain batch.
Once you find the transaction the approval code will be listed under Auth #.
By authorization log:
If you don’t have the batch number but you know what day the transaction took place you can filter the dates in the authorization log to view all of the transactions for that specific day.
Once you find the transaction the approval code will be listed under Auth #.
By card search:
Filter the date at the top of the page to the desired time frame you would like to search and enter in the last four numbers of the card.
Once you find the transaction the approval code will be listed under Auth #.
