// The Challenge

Why professional services need
an API Portal.

If you integrate, document, and make APIs usable for clients, you know the problem: legacy systems without docs, workflows nobody understands — and project deliverables that go dark after go-live.

Every project starts from scratch

No template, no standard, no reuse. Every new API documentation effort costs time — even though 80% of the work is always the same.

Client APIs without documentation

Grown system landscapes at the client: APIs exist, but nobody knows exactly what they do, who uses them, or how they connect. Before you can integrate, you have to inventory.

Workflows explained, not experienced

API workshops, acceptance meetings, handovers — all of these work better when clients can try APIs live. Static docs and PDFs convince nobody.

// Use Cases

Built for
Professional Services & Consulting.

Consulting Projects

Capture, structure, and bring client APIs to life.

Bring order to your clients' grown API landscapes: document existing interfaces, map workflows in a structured way, and hand over a living portal — not a static PDF, not an outdated Confluence page.

  • Quickly capture and document existing APIs
  • Make workflows and API dependencies visible
  • Try-it-out console for API workshops and acceptance sessions

Your portal. Under your brand. For every client.

Deliver the API Portal under your own branding — or in your client's corporate design. Logo, color scheme, domain. The client sees their brand, you keep control.

  • Custom branding per client (logo, colors, domain)
  • Your own portal product — without building from scratch
  • Clients experience your quality, not the tool behind it

// Security & Data Isolation

Built for
professional consulting projects.

Data isolation, branding control, and EU hosting — so you and your clients stay on the safe side.

Strict tenant isolation

Every client has isolated data areas, users, and roles. Cross-tenant visibility is technically impossible.

Your brand, your control

Clients experience your portal, not the infrastructure behind it. Full control over branding, domain, and user management.

GDPR / EU hosting

All client data stays in Frankfurt. Full control, no detours.

On-premise available

For clients with strict requirements: self-hosted deployment in their own infrastructure — even air-gapped.

// API Landscape

Client APIs structured,
documented, and made usable.

Typical APIs from consulting projects — captured, structured, and delivered as a living portal.

REST Integration v2.1

ERP Integration API

Order processes, inventory data, and delivery status from the ERP system — documented in a structured way and made usable for downstream systems.

GET /orders/{orderId}/status
POST /inventory/reserve
REST Identity

Identity & Access API

SSO integration, roles, and access rights — the workflow behind every user login in the client portal, cleanly documented and testable.

POST /auth/token
GET /users/{userId}/permissions
REST Notifications

Notification API

Event-driven notifications — email, push, and webhook mapped in a single workflow. Directly testable in the portal for acceptance and workshops.

POST /notifications/send
GET /notifications/{id}/status
REST Reporting

Reporting API

Data retrieval for dashboards and analytics — existing client reporting data made available in a structured way and documented for third-party applications.

GET /reports/summary
POST /reports/export
REST Workflow

Process Automation API

Turn manual steps into automated workflows — approval processes, status transitions, and escalation rules documented and fully traceable.

POST /workflows/{id}/trigger
GET /workflows/{id}/history
REST CRM

Customer Data API

Customer master data, contract info, and communication history from the CRM — made accessible in a structured way for portals, Self-Service, and integrations.

GET /customers/{id}/profile
PATCH /customers/{id}/contact
“We now deliver the API Portal as a standard part of our digitization projects. The client gets a living portal instead of a static document — and we have a differentiator that no other consultancy offers in this form.”
3x faster project deliverables

// Architecture

Seamless integration into existing client landscapes.

The API Portal integrates into client projects and existing system landscapes — from API gateways and identity providers to CI/CD pipelines. Automatic synchronization on every deployment.

  • CI/CD pipelines & developer workflows
  • SSO via SAML / OIDC configurable per tenant
  • ERP, CRM & API gateway connectivity
  • Infrastructure-as-Code support
  • On-premise & private cloud deployment

Each tenant can have its own branding — logo, color scheme, favicon, and custom domain. Your clients see exclusively their own brand. You manage all portals centrally via a management dashboard, without clients ever noticing the multi-tenant architecture.
The API Portal uses strict tenant isolation at the data and access level. Each tenant has isolated data areas, its own users and roles, and separate API catalogs. Cross-tenant visibility is technically impossible — even for administrators of other tenants.
Yes. We offer flexible licensing models for service providers — from package pricing for small client bases to volume-based models for system integrators, consultancies, and MSPs. Partner programs with reseller terms are also available.
Yes. The API Portal imports OpenAPI 3.x, Swagger 2.0, and AsyncAPI specifications. Existing documentation can be automatically imported via CLI, API, or Git sync. Our professional services team assists with complex client landscape migrations.
Yes. The API Portal can be deployed as a self-hosted solution in your own infrastructure or in your clients' infrastructure. Ideal for regulated industries or clients with strict data sovereignty requirements. Air-gapped deployments are also supported.
