ZarinPal

1. Log in to your ZarinPal panel at zarinpal.com and open your accepting account's settings to find the Merchant ID (a 36-character code) — paste it below. 2. No separate webhook needs registering: the callback URL is generated automatically for each payment and sent to ZarinPal at checkout time. 3. Turn on Sandbox mode below while testing — it routes payments through ZarinPal's test gateway instead of charging real money. 4. Set Account currency to match what your ZarinPal panel is configured in (Rial or Toman) — this only affects the unit amounts are sent in, not what the customer sees. 5. The Refund access token is optional; without it, refunds must be issued manually from the ZarinPal panel instead of from this dashboard.
