Most high-risk card processors can give you an Authorize.net account for this.

  1. Open Payment methods and find "Card payments".
  2. Enter your API Login ID, Transaction Key and Signature Key from Authorize.net.
  3. Leave "Test mode" checked while you are testing; no real cards are charged.
  4. Click "Turn on card payments".

In Authorize.net, add a webhook for "payment authorized and captured" pointing at the address shown on this page. Buyers pay on Authorize.net’s own page; card numbers never touch Purity.
