Integration Checklists

Purpose

This page provides a reference-only checklist for integrating with GMG Engine surfaces (APIs, schemas, and operational handoffs). It is intended to reduce ambiguity during implementation and review without implying availability, SLA, correctness, or outcome guarantees.

This page is descriptive and informational only and must not be interpreted as a guarantee, certification, endorsement, or system-wide claim.

How to Use This Checklist

Items below are review questions and implementation reminders. Completing the checklist does not imply that an integration is correct, secure, compliant, production-ready, or equivalent across deployments.

Examples and terms here are non-exhaustive and may not apply to every operator, whitelabel, or network context.

1) Identity and Scope

Have you identified the exact integration surface (API route, schema version, and environment)?

Is the integration scope stated (networks, assets, brands/whitelabels, and time window)?

Are roles and responsibility boundaries clear (engine vs operator vs whitelabel configuration)?

2) Versioning and Compatibility

Are schema and contract/interface versions explicitly pinned where applicable?

Are backward/forward compatibility assumptions stated rather than implied?

Are changelogs or version notes treated as references, not guarantees of behavior?

3) Data Formats and Validation

Are required fields, optional fields, and allowed ranges explicitly validated?

Are numeric fields treated with correct units (decimals, smallest units, currency denomination)?

Are timestamps and ordering assumptions explicit (source of time, timezone, sequencing rules)?

4) Error Handling and Retries

Do you handle partial failures, timeouts, and transient errors without assuming system failure?

Are retries bounded and idempotency-safe where relevant?

Do you avoid interpreting error messages as compliance, fraud, or enforcement conclusions?

5) Observability and Evidence Surfaces

Are logs and traces treated as diagnostic artifacts rather than proof of correctness?

Are correlation identifiers used consistently for cross-system debugging?

Do you separate “observed events” from “conclusions” in monitoring and reporting?

6) Security and Secrets Hygiene

Are API keys, signing keys, and secrets stored and rotated according to your own operational controls?

Are least-privilege assumptions documented (what access is required, and what is not)?

Do you avoid representing security practices as guarantees or certifications?

7) Network and Chain Assumptions

Are network-specific confirmations/finality assumptions explicitly stated and versioned?

Do you treat chain explorers and public traces as evidence surfaces, not outcome guarantees?

Are off-chain dependencies acknowledged where on-chain data is incomplete for the workflow?

8) Fees, Pricing, and User-Facing Labels

Are fee labels (network fee vs service fee vs withdrawal fee) clearly scoped?

Do you avoid implying fixed or permanent fee rates unless explicitly time- and policy-scoped?

Are examples treated as illustrative rather than binding commitments?

9) QA and Release Boundaries

Are test cases scoped to a specific version and environment?

Are “pass” results treated as context-bound signals rather than guarantees?

Are rollback and change-control procedures treated as operational practices, not assurances?

Disallowed Inferences

Do not infer availability, uptime, SLA compliance, or performance guarantees from this checklist.

Do not treat checklist completion as certification, audit, or endorsement.

Do not escalate integration artifacts into claims about legality, compliance, or fraud absence.

Boundary Conditions

This page does not define authoritative API behavior, network rules, or contractual obligations. It does not replace independent testing, security review, or operator-specific implementation requirements.

Non-Goals

This page does not guarantee integration success, correctness, security outcomes, or user experience. It does not provide legal, financial, or compliance advice.
