Infrastructure

API & Systems Integration

We connect business applications so required data and actions move in a controlled way: system A -> API / webhook / middleware -> system B.

First screen

We connect business applications so required data and actions move in a controlled way: system A -> API / webhook / middleware -> system B. EUR 50/hour. CTA: Request a systems integration estimate.

02PRODUCT READER

What problem does it solve?

Removes manual transfers and isolated systems across ecommerce-ERP, inventory, orders, invoicing, payment status, marketplaces, SaaS and other platforms that need to communicate.

03PRODUCT READER

What does the product do?

We build source -> authentication -> request/event -> transformation -> destination -> validation and define direction, endpoints, mapping, IDs, errors, limits, security and QA.

04PRODUCT READER

What you receive

System/API analysis, use case, endpoint/data/value mapping, auth, API requests, webhooks, middleware, transformations, validation, identifiers, duplicate/error/rate-limit handling, test/production setup, QA, docs and handover.

05PRODUCT READER

How we work and commercial model

Systems -> use case -> direction -> docs -> source of truth -> endpoint/data/ID mapping -> connection/auth -> transformations -> validation/errors -> tests/failure cases -> reconciliation -> QA -> docs. EUR 50/hour + external platform costs.

06PRODUCT READER

What we do not do / What we do not promise

27. What we do not do

No integration without use case, every endpoint, unnecessary middleware/complexity, bidirectional flow without source of truth, total data replication, personal passwords, ignored limits or implicit full workflow/data sync/custom software.

28. What we do not promise

No universal compatibility, access to unexposed functions, zero provider downtime/errors, universal real-time, removal of API limits, permanent compatibility after breaking changes or guaranteed commercial outcomes.

07PRODUCT READER

FAQ, complementary components and CTA

Connect APIs/ERP/WMS/ecommerce/invoicing/payments/couriers/marketplaces, webhooks, middleware and bidirectional flows where rules are clear.

08PRODUCT READER

Use case before API

We define what information leaves, from where, where it goes, when, who uses it and what happens next; only then choose endpoints.

09PRODUCT READER

Systems and interfaces

We may connect website, ecommerce, ERP, WMS, CRM, invoicing, payments, couriers, marketplaces, internal apps, SaaS and databases through REST, GraphQL, SOAP, proprietary APIs, SDKs, webhooks or file exchange, within real platform capabilities.

10PRODUCT READER

Webhooks and polling

Prefer event-driven flows where reliable webhooks exist; use periodic polling only where no suitable event exists and account for volume, limits and timing.

11PRODUCT READER

Authentication and access

OAuth, API keys, tokens, service accounts, signed requests or other official methods; define ownership, permissions, rotation and expiry. Personal passwords are not the standard architecture.

12PRODUCT READER

Mapping and transformation

Explicitly map fields/values and transform dates, currencies, phones, enums, units, addresses or payload structures where needed.

13PRODUCT READER

Identifiers and source of truth

Use stable IDs, SKU, order numbers or other business keys and define the authoritative system for each data domain to avoid conflicting overwrites.

14PRODUCT READER

ERP and WMS integration

ERP may expose customers, products, prices, orders, invoices and stock; WMS may manage inventory, reservations, picking, packing, shipments and locations. Scope depends on real APIs.

15PRODUCT READER

Ecommerce integration

Connect ecommerce with ERP, WMS, invoicing, payments, couriers, marketplaces, product systems or internal software; not all data needs bidirectional flow.

16PRODUCT READER

Payments and invoicing

Payment providers may expose initiated/authorized/captured/failed/refunded states; invoicing may receive customer/order/lines/tax/currency and return document IDs. We avoid unnecessary handling of sensitive payment data.

17PRODUCT READER

Couriers and marketplaces

May cover shipment/AWB/labels/tracking/status and products/offers/prices/inventory/orders within provider capabilities; one mapping is not assumed to fit every marketplace.

18PRODUCT READER

Middleware

Can isolate dependencies and handle routing, transformation, auth, logging and orchestration when point-to-point becomes fragile; we do not add it without a reason.

19PRODUCT READER

Point-to-point vs integration layer

For A<->B, direct connection may be enough; for ecosystems with many systems, an integration layer is used only where reuse and dependency management justify it.

20PRODUCT READER

Vs Process Automation

Integration answers how systems communicate; Process Automation answers which workflow executes using those connections.

21PRODUCT READER

Vs Data Synchronization & Processing

Integration builds the channel/contract; synchronization manages recurrence, consistency, reconciliation and ongoing processing.

22PRODUCT READER

Vs CRM Integration

Use CRM Integration when CRM is the central object; use general integration for ERP/WMS/ecommerce/payments/marketplaces/internal apps.

23PRODUCT READER

Real-time, periodic and rate limits

Connections may be event-driven, near real-time, periodic, batch or on-demand. Respect request rates, quotas, batch/payload sizes and concurrency; no universal real-time promise.

24PRODUCT READER

Errors, retry and recovery

Handle timeout, unavailable API, invalid credentials, rejected payloads, rate limits, missing records and server errors through retry/backoff/queue/log/alert/manual recovery where justified.

25PRODUCT READER

Duplicate requests and idempotency

Protect where relevant against duplicate orders/invoices/shipments/records and repeated financial actions using system capabilities and project logic.

26PRODUCT READER

Security and confidentiality

Minimum permissions, secure transport, controlled secrets, input/output validation, restricted endpoints and data minimization for customer/employee/financial/operational data.

27PRODUCT READER

Test vs production

Use development/test/sandbox/staging where available and adapt launch where a platform offers no separate test environment.

28PRODUCT READER

QA and reconciliation

Test auth, requests, mapping, transformations, IDs, accepted/rejected records, duplicates, missing fields, unavailable APIs and limits; reconcile sent, arrived, accepted and rejected records.

29PRODUCT READER

Documentation and ownership

Document systems, use cases, endpoints, auth model, mappings, transformations, IDs, source of truth, errors, limits, dependencies and testing. Accounts and systems remain under business control.
