The challenge: dependencies across teams

Established API engineering practices

API products still depended on business and technology teams working across organisational boundaries.

Customer journeys and partner integrations had to fit internal services, legacy systems and compliance obligations.

Teams needed shared requirements, clearer ownership and coordinated delivery decisions.

05

Collaborative discovery in the payments case

What the team did

APIsFirst and Osaango facilitated iterative workshops with business stakeholders, architects and engineers.

What the canvases made visible

Customer and API consumer journeys, value propositions, business rules and operating constraints.

Payments example: consumer details, payment method access, business risks and internal or partner channel needs.

06

Customer Journey Canvas: a supplier payment

Customer and trigger

A small business owner has a supplier bill due and wants to know the payment has completed.

The customer journey

1. Open the due bill
2. Choose the payee
3. Choose a payment method
4. Confirm the payment
5. Check the receipt

Illustrative example. Not a client artefact.

07

API Value Proposition Canvas: the same journey

Customer concern to API feature

Unclear payment status: show progress and a receipt. Repeat-payment concern: prevent duplicate submissions.

Candidate API products

• Payee Check API
• Payment Methods API
• Payments API
• Payment Status API

Illustrative example. API names are provisional.

API product management in everyday work

• Consumers and value: Who uses the API, and what does it help them do?
• Ownership: Who is responsible for the product over its lifecycle?
• Reuse and adoption: How can other teams discover and use the capability?
• Lifecycle decisions: How should the product evolve as needs change?
• Governance and developer experience: How do practices support product outcomes?

APIOps Cycles

11

Portfolio planning coordinated API releases

Which APIs to create, improve or release, and in what sequence

API portfolio planning

Priorities reflected partner integrations, UI development and dependencies between provider and consumer teams.

Capability improvement

A complementary view addressed API discoverability, governance, developer experience and product management.

12

The value across products, portfolio and ways of working

Connected work made decisions easier to discuss and repeat

Qualitative benefits of the engagement. No quantified delivery or business impact is claimed.

APIOps Cycles

13

Architecture: business needs become operating decisions

The next station needs architecture choices that stakeholders have reviewed.

APIOps Cycles

14

A payment requirement can change the architecture

Illustrative choices to validate, rather than facts about the client implementation.

APIOps Cycles

15

Trust boundaries and capacity need explicit answers

Trust and access

• Identify the caller and permitted payment objects.
• Agree exposed endpoints, network paths and data locations.

Demand and resilience

• Measure normal and peak demand before setting limits.
• Test retries, delays and recovery without duplicate processing.

APIOps Cycles

16

API design starts with shared domain meaning

Payment and payee

A payment is an instruction with an amount, currency, payee and a lifecycle status.

Business rules shape the contract

• Keep accepted, pending and completed meanings distinct.
• Agree ownership and the source of truth for state changes.

APIOps Cycles

17

Interaction design precedes the interface contract

The Interaction Canvas explores the flow; REST, Event or GraphQL canvases refine the chosen style.

APIOps Cycles

18

Contract-first design makes behaviour reviewable

POST /payments
Idempotency-Key: <request-key>

201 Created
{
  "paymentId": "pay-42",
  "status": "pending"
}

Decisions around this operation

• Define amount, currency, payee and validation errors.
• Specify replay scope, retention and conflicting-payload behaviour.
• Declare authentication and required permissions.
• Keep resource creation distinct from payment completion.

Illustrative contract excerpt. The idempotency policy still needs agreement and implementation.

19

The scaffold gives people and AI a shared workspace

npm create apiops@latest payments
cd payments
npm run method:start
npm run method:canvases:new-api

Choose API Productization and REST in the prompts. The tooling requires Node.js 22 or later.

The starter includes a sample Catalog contract; your team builds the payment runtime in its chosen language.

APIOps Cycles

20

AI needs the decisions behind the contract

AGENTS.md and package skills provide a route through the method; the team still validates the decisions.

APIOps Cycles

21

Building with AI works best as a bounded change

1. Select one reviewed operation and its acceptance criteria.
2. Ask for an implementation diff and tests against the contract.
3. Run checks, inspect behaviour and record unresolved decisions.
4. Have the responsible people review the evidence before merging.

Suggested task: implement payment submission with replay and cross-partner denial tests.

APIOps Cycles

22

Tests turn the payment promises into evidence

These tests extend the scaffold with runtime evidence for the chosen implementation.

APIOps Cycles

23

Linting checks the contract against explicit rules

npm run lint:openapi:full-crud

The full-crud name permits writes; it does not require every CRUD operation.

The scaffold validate:openapi command runs both profiles, so a write-enabled API needs a deliberate profile choice.

APIOps Cycles

24

API Audit brings evidence together across the lifecycle

npm run audit:design:full-crud

The report uses pass, partial, gap and not applicable. Manual items require evidence and owner review.

APIOps Cycles

25

A check result needs a clear interpretation

Adapt the starter checks to the API domain before treating coverage as a release decision.

APIOps Cycles

26

CI can keep the review evidence current

Included scaffold workflow

1. Install dependencies with npm ci.
2. Lint the selected profile and generate audit reports.
3. Publish the JUnit coverage result as a GitHub check.

Extend for the payment implementation

• Run contract, integration, security and load tests.
• Define which lint findings, gaps and failed tests block release.
• Review changes to contracts, controls and generated evidence together.

Audit outputs: JSON for tooling, Markdown and HTML for review, JUnit for CI.

APIOps Cycles

27

Publishing and improvement complete the product cycle

API Publishing

• Publish the reviewed contract and consumer-facing examples.
• Make access, onboarding and support ownership clear.
• Keep service terms and operational responsibilities visible.

API Monitoring & Improvement

• Observe payment completion, pending age, latency and errors.
• Combine runtime evidence with adoption and consumer feedback.
• Revisit architecture, contracts and priorities when assumptions change.

The next improvement starts with evidence from consumers and operations.

APIOps Cycles

28

A first working cycle

1. Agree one API product, a consumer journey and an accountable owner.
2. Record the architecture choices and review one contract.
3. Build one path with AI assistance and meaningful tests.
4. Lint, audit and share findings before the next release decision.
