Custom Integrations

When standard integrations are too rigid, we build the right solution — tailored, documented, and maintainable long-term.

When do you need a custom integration?

No standard connector

You use an internal system with no off-the-shelf integrations.

3+ systems to sync

Standard tools get tangled with multiple data paths.

Compliance requirements

Data shouldn't flow through third-party tools — GDPR or NDA.

Performance at limits

Data volume exceeds no-code platform limits.

Typical integrations

ERP ↔ CRM sync

Bidirectional between DATEV/SAP and HubSpot/Salesforce/Pipedrive.

AI providers

OpenAI, Claude, Gemini, open-source — with caching, rate limiting, cost monitoring.

Payment gateways

Stripe, Mollie, PayPal, SEPA for subscriptions, splits, multi-currency.

Slack/Teams bots

Custom bots talking to internal systems — tickets, reports, data validation.

Custom webhooks & APIs

RESTful, GraphQL, or event-based — the APIs your systems need.

Data migrations

One-time or recurring — CRM switches, data warehouse consolidation.

Our approach

1

API analysis

Both systems: docs, limits, auth, rate limits, data types.

2

Architecture design

Sync vs. async? Event-driven vs. polling? Workflow engine or custom service?

3

Implementation

Clean, tested, documented integration — TypeScript/Python or as a workflow component.

4

Monitoring & alerting

Built-in logs, metrics, error alerts. You know immediately when something breaks.

5

Documentation

Full technical docs so your team can maintain and extend the integration.
