Integrations & Automation

API Integration

Reliable API-to-API connections with auth, retries, monitoring, and clear ownership.

API Integration connects systems through documented contracts rather than fragile scripts. We design the data flow, handle authentication and failure paths, and leave you with observability so a vendor outage or schema change does not become a silent data gap.

Who it’s for

  • Product and ops teams stitching SaaS platforms together
  • Engineering teams replacing brittle spreadsheet bridges
  • Companies exposing or consuming partner APIs

Problems we address

  • Manual copy-paste between systems creates errors and delay
  • One-off scripts fail without anyone noticing
  • Auth and rate limits were never designed for production load

Expected outcomes

  • Mapped field contracts and ownership for each flow
  • Idempotent sync or event handling with retries
  • Monitoring and alert hooks for failure classes that matter

Timeline

Typical timeline

2–6 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

Whichever fits durability and cost. Simple flows may use Make/n8n; high-volume or sensitive paths often need custom workers.
