MEMEH RTPO — UAT & Certification

UAT & certification

UAT confirms enablement, payment-request handling, participant-delegated alias resolution, payee_bic selection, adapter-to-provider delivery, lifecycle events, credentials, downloads, and operator evidence before production enablement.

What “done” looks like

The integration demonstrates correctness, security boundary enforcement, and operational visibility with audit-grade evidence. Deviations are documented with approval and risk acceptance.

Recommendation: run UAT with both request-submitter and participant stakeholders present to validate both one-alias calls, internal API delivery, lifecycle events, and ownership boundaries.

Keep artifacts versioned. When you re-run UAT, start a new execution cycle and preserve prior evidence.

Coverage areas

UAT must validate both the technical integration and the operational governance surfaces.

Functional

Two-step fintech intake, two participant one-alias calls, all-or-nothing combination, provider delivery, lifecycle events, and state transitions.

Security

HMAC and internal-key authentication, payee_bic assertions, participant API TLS, idempotency, lifecycle deduplication, and boundary rejection.

Reliability

Either-alias failure, timeouts, retries, duplicate deliveries, durable outbox, and recovery behavior.

Enablement portal

Access review, credential lifecycle, UAT evidence, and operator accountability outside Core.

Negative testing

Invalid credentials, unknown or inactive alias, route mismatch, malformed payloads, and illegal lifecycle transitions.

Fintech workflow

Workspace access, artifacts/downloads, and readiness gates.

Suggested flow

A structured sequence that reduces rework and keeps evidence defensible.

1

Prepare environment + participant boundary

Confirm sandbox/UAT setup, roles, directional credentials, payee_bic test data, participant one-alias path, RTP path, and adapter configuration.

2

Execute baseline happy paths

Resolve payer and payee, select active financial-address options, submit their opaque IDs, verify adapter delivery to the provider API, and confirm lifecycle events.

3

Run security + negative cases

Validate boundary enforcement and explicit rejection behavior.

4

Confirm visibility alignment

Ensure operator views and partner views match runtime outcomes.

5

Sign-off + readiness gate

Record evidence, resolve defects, and complete approval for production enablement.

Evidence model

Evidence must be reproducible and traceable. Use the tracker for consistent collection.

Field	Description	Example
Test case ID	Unique identifier for repeatable execution.	UAT-FN-001
Date executed	When the test ran.	2026-03-26
Environment	Sandbox / UAT (staging) / production-path test.	UAT
Outcome	Pass / Fail / Blocked.	PASS
Observed behavior	Notes and deviations from expected behavior.	Callback received within 3s; status transitions correct.
Evidence links	Screenshots, logs, tickets, correlation IDs.	JIRA-1234 / trace_id=abc

Acceptance criteria

Readiness gates required before production enablement.

High-priority functional cases pass

No open functional defects that block core flows.

Security-critical cases pass

Authentication, boundary rejection, idempotency, event deduplication, and transition controls behave correctly.

No unresolved critical defects

Critical severity issues are closed or formally waived with approval.

Provider lifecycle confirmed

Provider events are correct, timely, and retry-safe across intermediate and terminal states.

Runtime configuration is traceable

The approved provider route and adapter snapshot used by Core can be correlated with execution evidence.

Sign-off recommendation

Final sign-off should include operator approval, partner confirmation, and recorded evidence links for audit traceability.
