How It Works

From zero to live payments
in under 10 minutes.

Three steps. One API. No blockchain expertise required.

01

Generate Your API Key

Dashboard → API Keys → Create New

Log in to the dptcay dashboard, navigate to the API Keys panel, and generate a scoped key in seconds. Choose read-only, write, or webhook permissions per key — no global access by default.

Keys are encrypted at rest with AES-256 and displayed only once at creation.

From solo builders to fintech agencies — real teams running real production workloads on dptcay.

I integrated dptcay into my SaaS app in under two hours. The API is dead simple — clean endpoints, predictable responses, and the key management dashboard is exactly what an indie dev needs: no bloat, just control.

We switched our entire checkout flow to dptcay after our previous gateway went down during Black Friday. Since then — zero downtime, 99.99{a45820a93bc22531c72a4f2910eeaaf7521141634e469edaf23280f50c26f783} uptime, and rotating API keys without a single service interruption. It's the backbone of our payments.
