Manual bottlenecks
- Ops-created payouts don’t scale and error often.
- ERP/order systems drift from payment status.
- Inconsistent errors and retries make incidents hard to trace.
Enterprise API
We provide REST-style integration guidance and event notification patterns so engineering and finance can go live compliantly—actual endpoints, fields, and versions are in your technical pack after onboarding.
HTTPS & keys
Key rotation, scopes, and safe rate practices.
Webhooks & signatures
Delivery, verification, and replay protection.
Versioning
Compatibility cadence to reduce surprise changes.
Automatable, observable, and rollback-friendly integration boundaries.
Auto-create payouts after checkout; sync order/invoice.
Recurring charges with failure retries.
Batch files or queues plus reconciliation exports (product-dependent).
Switch operation and environment to browse a JSON structure preview (field names/types per official docs).
Operation
Environment
Static preview only—not a live API; follow the technical handbook and key issuance process.
Subject to product specs and contracts.
API keys, signatures, and IP allowlists.
Create, fetch status, cancel/expiry flows (module-dependent).
Webhook backoff and dead-letter patterns.
Sandbox, logs, and alerting alignment.
FAQ
Sandbox validates connectivity and payloads without moving real funds; production requires onboarding, keys, and scopes.
Follow the technical pack—shared secret or public-key verification with timestamp/replay checks.
Overlap keys: issue new credentials, update backends, monitor traffic, then retire the old key with least-privilege scopes.
Create-style calls typically accept idempotency keys; webhook delivery uses backoff patterns per module/version.
End-to-end sandbox tests, error-code mapping, TLS/signature on webhook endpoints, and finance field alignment.
