Integrations & Automation

Custom Integrations

Bespoke connectors and middleware when off-the-shelf automation tools are not enough.

Custom Integrations cover the cases iPaaS cannot: awkward legacy APIs, high volume, strict security boundaries, or multi-step orchestration that needs real engineering. We build maintainable connectors with tests, observability, and docs your team can own.

Who it’s for

  • Teams blocked by SaaS tools without native connectors
  • Companies with legacy systems that only speak odd protocols
  • Platforms needing partner integrations under their brand

Problems we address

  • No native connector exists for a critical system
  • iPaaS hits limits on volume, latency, or compliance
  • Previous custom scripts are undocumented and fragile

Expected outcomes

  • Purpose-built connector or middleware for the use case
  • Clear interfaces and operational metrics
  • Documentation and handover for ongoing ownership

Timeline

Typical timeline

3–10 weeks

Timeline depends on scope, access, and dependencies—not a delivery guarantee.

Process

A clear delivery path from discovery through handover and optional support.

  1. 01

    Discovery

    Goals, constraints, success criteria, and current-state review.

  2. 02

    Architecture

    Target design, interfaces, risks, and delivery sequence.

  3. 03

    Implementation

    Incremental build with visible progress and documented decisions.

  4. 04

    Testing

    Functional checks, failure paths, and acceptance criteria validation.

  5. 05

    Deployment

    Controlled release to staging and production with rollback paths.

  6. 06

    Handover

    Runbooks, access notes, and operator/admin walkthrough.

  7. 07

    Support

    Optional hypercare window or retainer continuity after go-live.

FAQ

When volume, latency, security boundaries, complex state, or long-term maintainability make visual automation tools a poor fit.
