Lynnbrook Classic

Lynnbrook Classic is a deprecated payment method. It has been superseded by a new Lynnbrook Group option which you can see at the top of the recommended processors list. Lynnbrook is no longer accepting new applications for Lynnbrook Classic, but if you have an existing Lynnbrook Classic payment method you can continue to use it.

In order to use the Lynnbrook Classic gateway account with OwnerRez, there are a set of API credentials that you will need to retrieve from Lynnbrook Group and enter in OwnerRez.

Once you've clicked Connect Lynnbrook Classic payment method in OwnerRez, you will notice you are asked to enter four fields under "API Credentials", at the top of the page:

  • Username
  • Password
  • Merchant Code
  • Account Code

These items are provided to you by Lynnbrook Group. If you can't find them, please contact Lynnbrook (support@lynnbrookgroup.com) directly to get a new copy.

The "Account Code" field may be referred to as "Merchant Account Code".

After filling in these four fields, perform a quick test. Use the 'Test API Credentials' button to see if everything validates. This sends a request to Lynnbrook with your API credentials. OwnerRez checks the response that Lynnbrook sends back to see if it looks right.

If all looks good, finish filling out the rest of the page. Make sure you click 'Save' at the bottom when finished.

Test, Test, Test

Even if the test came back successful, to completely test your integration, you'll want to do a test transaction using a real credit card. There is no better way of testing your API Credentials than running a real credit card. To do that, create a manual booking, collect a payment using your personal credit and a small amount (say $5). Once it goes through, use the Void & Delete option on the payment to void the credit card payment. Then cancel or delete the booking. That will tell you definitively that everything is good to go.
