A useful proof reduces one technical uncertainty with working evidence. It does not recreate the buyer's platform or imply that an evaluation artifact is production-ready.
Write the workflow as a concrete transaction
Name the initiating user or system, representative input, source API operation, transformation, target-system action, expected response, durable result, and evidence the prospect will inspect. A workflow such as create an approved support case from one normalized event is testable. A scope such as integrate with the enterprise stack hides several identities, objects, policies, and failure modes behind one sentence.
Limit the proof to one source API, one target system, one connector or small application, one approved identity path, and no more than six acceptance criteria. Record the target environment, supported input shape, expected volume for the demonstration, and excluded variants. Additional workflows, production migration, broad role models, historical backfills, and continuing operations require separate decisions.
Make each claim point to evidence
Translate approved claims into observed checks. Can connect becomes a successful request and target record with joined identifiers. Handles a rejected input becomes a documented validation response that creates no target action. Can retry becomes a repeated approved request with stated idempotency behavior. Record request and response schemas, status, timing, transformation, identifiers, logs, and target state while redacting credentials and fields not needed for review.
Postman's 2025 State of the API report says API-first adoption is widespread while collaboration difficulties remain common. A shared evidence record addresses a narrow part of that problem: prospect, buyer, and implementer can inspect the same workflow and acceptance result. It does not resolve enterprise governance, commercial terms, or production architecture outside the proof.
End with a bounded implementation decision
The handoff should show the working proof, failed cases, known limits, credential and environment inventory, reset procedure, fallback demonstration, architecture diagram, dependencies, and implementation estimate with assumptions. Separate reusable code from proof-only fixtures. Identify production questions such as scale, identity, observability, support, data retention, network controls, change management, and disaster recovery without claiming they have been solved.
Integration Proof Record is operated by Reality Contact, LLC. The buyer and prospect approve the workflow, data, claims, access, and acceptance criteria and decide whether the evidence supports a production commission. The proof demonstrates named behavior in an isolated environment. It does not certify security, compliance, reliability, scalability, production readiness, procurement fit, or any business outcome.
Where the service stops
Reality Contact, LLC builds a one-workflow evaluation artifact but does not certify security, privacy, compliance, reliability, scalability, production readiness, procurement fit, or business outcomes; approve enterprise architecture; operate production; or represent the prospect's acceptance decision. The buyer and prospect approve the workflow, claims, sanitized data, constraints, target-system actions, and acceptance criteria; control credentials and access; attend the evidence review; and decide whether to commission a separately scoped production implementation. The service is software implementation and document preparation for one evaluation workflow, and it does not replace security, privacy, compliance, architecture, procurement, reliability, or production review. The buyer and prospect approve the workflow, data, claims, access, and acceptance criteria and retain every production, procurement, architecture, and commissioning decision.
