You can accept payments using HSA cards by following the steps below:

1️⃣  Set up a Stripe account via our platform. Please refer to this article for more information on how to create a Stripe account on the platform. 

2️⃣ Contact Stripe directly to configure the ability to accept HSA payments through your OnCall account. 

🔔 Note that HSA cards require that your business has a special classification (MCC or Merchant Category Code) set, so card companies recognize your products and services as related to a client's medical needs. 

⚠️ Keep in mind that having an account enabled for HSA payments doesn't guarantee a card won't be declined. Card issuers can still authorize or decline payments as they would with any other credit card.
