Test-mode examples

Stable identifiers. Explicit states. Safer retries.

The examples demonstrate the intended integration pattern; endpoint availability and credentials follow successful onboarding.

Bearer credentials scoped by environment
Idempotency on money-moving requests
Signed webhooks as asynchronous evidence

Questions

Practical answers before implementation.

Commercial and technical details are confirmed for the specific entity, use case and approved programme.

How does implementation begin?+

PayDrion first maps your business model, transaction flow, expected volumes, risk profile and required payment rails. An implementation plan and test credentials follow successful onboarding.

Can this be enabled for every business?+

Availability, limits, pricing and settlement timelines depend on onboarding, use case, bank or network partner approval, and applicable regulation.

How are transaction states confirmed?+

Use the synchronous API response for immediate context, then rely on signed webhooks and server-side status verification as the operational source of truth.
