API INTEGRATION_
API contracts that survive production — not slideware specs
Parallaxis productizes an API and event integration layer on OpenAPI, GraphQL, Kafka, and RabbitMQ: discover → design → contract → connect → operate. Same contract, real consumers, operate after connect — not swagger-in-a-deck theater.
Every engagement builds an API integration layer on integration tech enterprises already hire for. Tap the stages on the right.
API integration layer_
Discover through operate — contracts, events, and consumer paths on OpenAPI, GraphQL, Kafka, and RabbitMQ. Tap a stage.
Discover_
Stage 01 / 05
Map who consumes what before you write specs
Surfaces, owners, and failure modes — so the integration layer starts from real traffic, not a wish list.

- Seams

02 · SPECS VS INTEGRATION LAYER_
Same integration. Two very different paths.
Toggle Spec theater vs API integration layer — watch where integration dies or completes.
Same constraint_
“We need this API live Friday — and the only OpenAPI file is a stale Confluence export.”

Outcome_
Spec theater
Slideware contracts, tribal Postman collections, and hope. Connect is a guessing game.
03 · CONTRACT PRESSURE_
Confidence dies when contracts are hoped
Toggle contract pressures — watch the confidence score and how fragile an integration becomes.

Outcome_
Tightening the integration layer
Some schemas exist — still too much tribal knowledge in connect.
04 · ENDPOINT × GATE_
Probe the cell before you connect
Pick an endpoint surface and gate — see blast if it fails and which controls belong on the integration layer.

Blast if this fails_
Consumers parse garbage — silent breakage across clients.
Controls on the integration layer_
- Schema lint
- Required fields
- Block on drift
Operator note_
Treat the schema as the artifact of record, not a nice-to-have.
CAPABILITY_
How we use the stack — not slideware logos
Each mark is a capability we deliver: contracts that review, events that own DLQs, and operate loops after connect.
OpenAPI / Swagger
Linted, versioned OpenAPI as the artifact of record — not a Confluence export that drifted from prod.
GraphQL schemas
Schema registries, review gates, and cost controls so nested queries do not become production debt.
Apache Kafka
Topics with schemas, ACLs, lag alerts, and DLQ ownership — not fire-and-forget pub/sub theater.
RabbitMQ
Queues, retries, and dead-letters with named owners so async paths stay operable.
GitHub reviews
Contract PRs with required reviews — schema change is a gated path, not a chat zip.
Dockerized contract tests
Consumer/provider suites that run the same way in CI — prove compat before connect.
05 · INTEGRATION HANDOVER_
What an API integration layer engagement leaves behind
Open a chapter — discover through operate. Vocabulary the owning team runs next.
Integration handover chapters_
5 chapters- Surface inventory
- Owner map
- Failure modes
In scope_
- API integration layer: discover → design → contract → connect → operate
- API / event productization and consumer gates
- Integration handoff so the owning team can run contracts
Out of scope_
- ERP/CRM integration backbone programs (see Enterprise Integration)
- Data sync layers without API ownership (see Data Integration)
- Application product squads without an integration constraint (see Product Engineering)
FIT_
Is API Integration the right next step?
Self-qualify — we work best when contracts, events, and consumer paths are the constraint.
Good fit_
- You need owned OpenAPI / GraphQL / event contracts — not another PDF
- Consumers break when producers “just ship” today
- Someone will own the integration layer after handoff — not a one-off swagger spike
Not yet_
- ERP/CRM silos need a coherent integration backbone (see Enterprise Integration)
- The primary pain is pipelines and warehouse sync (see Data Integration)
- You want product features shipped with no integration constraint (see Product Engineering)

Common questions
Our API Integration engagements run discover → design → contract → connect → operate, productizing OpenAPI/GraphQL/event contracts with an operate handoff — not spec theater.
