QUICK ANSWER
What is the System Integrations service?
API and system integrations for WooCommerce, CRM, ERP, accounting, couriers, payments, analytics and marketing automation. With System Integrations we connect API discovery and Data mapping with the user journey, technical dependencies, maintainability and the measurable business goal of the website. This way design and development decisions have a clear reason and acceptance criterion.
SCOPE OF THE SERVICE
What do System Integrations include?
API discovery
We check endpoints, authentication, rate limits, webhooks and the limitations of the systems before designing the integration flow.
Data mapping
We describe source and destination fields, transformations, required values and ownership so that there are no hidden data losses or mismatches.
Authentication
We choose the appropriate authentication mechanism and manage credentials and permissions with the minimum rights necessary.
Webhooks
We use webhooks for event-driven exchange, planning validation, idempotency, retries and protection against duplicate events.
CRM / ERP connections
We organize customer data, ownership and next actions across marketing, sales and service processes.
Payments / couriers
We check the critical path to completing a purchase, payment/shipping dependencies and failure cases that could lead to lost orders.
Logging / retries
We add error logging, a retry policy and exception handling so that a temporary problem in one system does not interrupt the whole process.
QA and monitoring
We test the happy path and failure scenarios and monitor the critical integrations after launch.
OUR PROCESS
How System Integrations work is carried out
- 01
Scope
We fix the goals, audiences and constraints and clarify how API discovery affects the final build.
- 02
Architecture
We map Data mapping, content/data dependencies and critical journeys before development begins.
- 03
Design decision
We turn Authentication into a responsive solution with clear states and acceptance criteria.
- 04
Build
We implement Webhooks in a controlled way and keep integrations, SEO and tracking dependencies visible.
- 05
QA
We test critical journeys, devices, forms, performance and edge cases before launch.
- 06
Launch & monitor
We launch in a controlled way, validate the real frontend and monitor errors, conversions and technical regressions.
DECISION SUPPORT
When do System Integrations make sense?
It is a good fit when
- The website has a clear business outcome that the current structure does not serve well
- There is a real need for API discovery or Data mapping, not just a cosmetic change
- SEO, tracking or integrations need to be part of the build from the very beginning
- You have an owner for content/decisions and we can fix the acceptance criteria before launch
What you will get
- A clear functional and content scope
- Responsive UX and technical acceptance criteria
- Launch QA for forms, performance, SEO and tracking
- A maintainable foundation for future integrations and content
When will System Integrations not solve the problem on their own?
Before starting, we check whether this service is the right next step and which dependencies could limit the result.
- When the business goal, the offer or the core audience have not yet been defined.
- When the necessary access, data or a decision-maker for the project are missing.
- When the problem lies in another layer of the customer journey and measurement, the website, content or inquiry follow-up need to be fixed first.
- When there is no capacity to implement the recommendations and maintain the changes made.
What determines the scope and price of System Integrations?
We do not use a fixed price, because the real scope is determined after reviewing the current state, goals and dependencies. The proposal describes the specific activities, responsibilities and acceptance criteria.
DISCUSS YOUR PROJECT- The current state and the diagnosis needed before execution.
- The number and complexity of the elements in scope, including API discovery and Data mapping.
- The number of markets, languages, channels, systems or integrations.
- The available content, data, design materials and technical access.
- The need for a one-off delivery, phased implementation or ongoing work.
How do we determine the timeline?
After the initial review we map the dependencies and divide the work into stages with a verifiable result. The timeline depends on the scope, the readiness of materials, external systems and the speed of feedback. Where possible, we deliver the tasks with the highest business impact first.
What is needed from your side?
We need the relevant access and available data, context about the business and its goals, a decision-maker and timely feedback. At the very start we clarify who provides content, technical help and approvals.
PRACTICAL SCENARIO
A practical approach to System Integrations
Integrations remove manual handoffs and create a traceable data flow between systems.

MEASUREMENT
How we measure success
Performance
CWV, loading and stability. For System Integrations we use this signal to check whether the build improves the critical journey without technical regressions.
Engagement
Behavior along the key journeys. For System Integrations we use this signal to check whether the build improves the critical journey without technical regressions.
Conversions
Forms, sales and other business events. For System Integrations we use this signal to check whether the build improves the critical journey without technical regressions.
Reliability
Errors, uptime and technical stability. For System Integrations we use this signal to check whether the build improves the critical journey without technical regressions.

FREQUENTLY ASKED QUESTIONS
System Integrations FAQ
We start from the current state, the goal and the dependencies around API discovery and Data mapping. Then we separate the must-have work from improvements that can be delivered in a later phase.
We need the relevant access, a decision-maker and real business context. When Authentication depends on data or another system, we clarify ownership and constraints before implementation.
We set acceptance criteria in advance and validate Webhooks with real scenarios. For data/integration tasks we compare sources, and for UX/content tasks we test the critical user journey.
We use Performance and the related business signals for the service. We do not accept a single isolated metric as proof of success when it does not reflect quality or a downstream outcome.
Critical URLs, redirects, metadata dependencies, analytics events and forms are included in pre-launch QA. For a migration/redesign we also run a post-launch check of the real frontend.
Yes. We split the work by dependencies and risk so that each phase has a usable output and its own QA. The practical context here is: integrations remove manual handoffs and create a traceable data flow between systems.
