AVS Settings :
Almost 80% of transactions possibly got declined due to AVS mismatch for card payment transaction.
Customizing AVS settings from merchant account can be helpful to control decline due to minor mismatch.
Authorize.net payment gateway allows to customize “Address Verification Settings” in your merchant account.
Login to your Authorize.net merchant account and find "AVS Settings" option to customize.
System rejects or verifies responses based on AVS settings for each type of AVS information as shown in below image.
As shown in above image there are two type of response set : 1. General AVS Responses and 2. Address & Zip Code Responses
So most order transactions declines can be controlled from each of these several responses to check for rejections or uncheck to pass without rejections as exactly shown in above image.
