You can add the Authorize.net payments processor to Bloomerang CRM and use it to process card and EFT transactions.
Important: New Bloomerang CRM customers who onboard on or after February 10, 2026, must use Bloomerang Payments to process transactions unless your organization is located outside of the United States. Organizations outside of the United States, including Canada and other countries, must use an integrated third-party processor (Authorize.net or Stripe) to process payments in Bloomerang.

Go to account.authorize.net.
Log in to your account with the credentials that Authorize.Net provided.
In the Account section, click Settings.

If you don’t have your transaction key, generate a new transaction key:
Type the answer to the secret question.
Click New Transaction Key. Make a note of this. You will use it in the next section on this page.
