Developers
Developer guidance for institutional infrastructure integrations.
These guides reflect the operational architecture underlying cross-border payment and treasury systems. They are practical reference material rather than a claim of a live Osai API surface.

Useful integration topics
Understanding a payment lifecycle
Map instruction intake, execution, settlement and reconciliation into one operational flow.
Integrating with a payment API
Use disciplined request design, versioning and clear lifecycle states for institutional integrations.
Idempotent transaction requests
Prevent duplicate execution when retrying payment or ledger instruction requests.
Handling asynchronous processing
Track status transitions, event confirmation and operational follow-up without guessing final state.
Webhook verification and retries
Verify source integrity and design deterministic retry behavior for downstream events.
Reconciliation workflows
Align internal ledger state with external payment and settlement records using shared evidence.
Sandbox-to-production readiness
Plan for credentialing, observability, operational review and support before wider rollout.
Responsible implementation
Design for clarity and evidence
Production integrations need reliable retry handling, measurable status transitions, security review and clear ownership. Osai’s documented approach emphasises operational transparency rather than overpromising production capability before there is a verified implementation.
