Pay-ins Workflow

Payments The pay-ins workflow involves two key personas: a Buyer purchasing goods or services using stablecoins and a Seller. The Seller represents either a merchant that provides goods or services, or a payment processor acting as the intermediary to facilitate the transaction. Most pay-in integrations follow a similar workflow for the Seller:
  1. Add a crypto deposit address for a designated Profile, using one of the supported blockchains.
  2. To use stablecoins for pay-ins, share the crypto deposit address with Buyers as a checkout option.
Using a wallet connector or displaying a QR code in the Buyer interface helps to ensure that Buyers send the correct amount and avoid errors.
  1. Configure a pay-in monitoring and reconciliation request to confirm Pay-in transactions on the Paxos Platform.
  2. Withdraw USD to a bank account.

​
Refunds Workflow

Issuing a refund is similar to pay-ins, except the funding flow is reversed: USD is first moved onto the Paxos Platform and then the stablecoin refund is sent to the Buyer’s designated wallet. Most refund integrations follow a similar workflow for the Seller:
  1. Send USD to a designated refund account.
  2. Initiate a crypto withdrawal to the Buyer’s designated wallet address, using one of the supported blockchains.
  3. Configure a refund monitoring and reconciliation request to confirm Pay-in transactions on the Paxos Platform.
