Setting Up Your Merchant Account
9 January 2025

Setting Up Your Merchant Account

The merchant account will allow non-members to join and pay online from your website, existing members are able to renew using a credit card, and your online store will also accept immediate payments. Additionally, your event registration system will allow members and the public to register and pay online for their registration. 


Below are the merchant accounts that we support:


  • Authorize.Net

When you are ready to have Chamber Nation activate your Authorize.Net merchant account you will need to submit a support ticket and provide the following information:


  1. Engineering would need your Authorize.net account's API Login ID and Transaction Key.
  2. You can find the instructions here on how you can obtain this information. https://support.authorize.net/knowledgebase/Knowledgearticle/?code=000001271


For seamless member billing, we recommend using Authorize.net as your merchant account gateway. The MMS integrates with Authorize.net's Customer Information Module (CIM), which allows us to securely store credit card information. If your system is connected to Authorize.net, the MMS can automatically charge member cards when an invoice is created.


If you are looking for low cost merchant account with additional benefits for NON-Profits we recommend www.ChamberMerchantAccount.com. On another note... if you are looking for PCI compliance information, sample privacy policy, etc. check out lower part of this page: https://www.chambernation.com/merchant-account
