Endpoint

POST https://api.digitzs.com/payments

​
Overview

Use this endpoint to refund a payment or void an eligible transaction. The system automatically determines whether to perform a refund or void based on the transaction timing and type.
Void vs Refund: If the transaction is eligible to be voided, the system will perform a void instead of a refund. Voids are processed faster and don’t incur additional processing fees.

​
Void Eligibility

Transactions can be voided under these conditions:
  • Card Transactions: Can be voided before 11:59 PM PST on the same day the transaction was processed
  • ACH Transactions: Cannot be voided through the API. Contact support for ACH transaction issues.

  2. Track Refunds: Monitor all refund transactions for reconciliation
  3. Document Reasons: Use miscData to record why refunds were issued
  4. Validate Amounts: Ensure refund amount doesn’t exceed original or remaining balance
  5. Customer Communication: Inform customers about refund processing time (instant void vs 3-10 day refund)
  6. Handle Splits: Use the split refund endpoint for split payments
