API Development & Integration — an illustration of the tools and systems involved

What we deliver

9 services in this discipline. Each one says what it includes and how we approach it — no jargon, no vague promises.

    01

    REST API Development

    Documented, secured APIs your own apps and outside partners can build against confidently.

    Designed around your domain, documented as it's built, and secured before it's exposed to anyone. Your own applications and outside partners get an interface that behaves consistently across every endpoint. Versioning is planned from the start so you can evolve without breaking existing consumers.

    02

    Third-Party API Integration

    Connect any external service — including the ones with confusing or incomplete documentation.

    We read the documentation, work out what the API actually does as opposed to what it claims, and build a resilient client with retries, timeouts and proper error handling. Poor or missing documentation is a normal working condition for us, not a blocker. Integrations are wrapped so that if the vendor changes, only one layer needs replacing.

    03

    Payment Gateway Integration

    Razorpay, Stripe, PayPal and UPI wired in with webhooks and proper reconciliation.

    Checkout flow, webhook signature verification, idempotency and reconciliation against your order records, so payments and orders never drift apart. We handle the failure paths — timeouts, partial captures, refunds, duplicate submissions — not just the happy case. Test and live environments are kept properly separated.

    04

    CRM Integration

    Two-way sync between your application and HubSpot, Zoho, Salesforce or a custom CRM.

    Two-way synchronisation with explicit field mapping, conflict resolution rules and a change log, so nobody has to guess which system holds the truth. Works with HubSpot, Zoho, Salesforce or a CRM you built yourself. Sync failures are surfaced immediately rather than discovered during a sales meeting.

    05

    ERP Integration

    Bridge your web systems with existing ERP data so nobody re-enters anything by hand.

    Your web systems and ERP exchange data on a schedule or in real time, removing the manual re-entry step that causes most data errors. We work with whatever interface the ERP exposes, including older file-based or database-level ones. Mapping and transformation rules are documented for your own team.

    06

    Custom API Development

    Internal APIs designed around your domain rather than bent to fit a generic template.

    Internal APIs modelled on your actual business objects rather than a generic CRUD template, which makes every later integration simpler and cheaper. Versioned so you can evolve them without breaking what already depends on them. Access is scoped per consumer, with usage visible per client.

    07

    API Security

    Authentication, rate limiting, key rotation and protection against abuse.

    Authentication, scoped keys with rotation, per-client rate limiting, strict input validation and protection against the common abuse patterns. Reviewed against the OWASP API security risks before launch rather than after an incident. Secrets are managed properly instead of living in a config file in the repository.

    08

    API Documentation

    OpenAPI specs and readable guides, so integrating doesn't require a phone call.

    An OpenAPI specification plus readable guides with working examples, so an outside developer can integrate without contacting you. Kept in the repository alongside the code, so it stays current instead of drifting a year out of date. Includes authentication, error formats and rate limits, which are the parts people always ask about.

    09

    Webhook Development

    Event delivery with retries, signature verification and a replay log for failures.

    Reliable event delivery with signed payloads, automatic retries with exponential backoff, and a searchable log you can replay from. Receivers get effectively exactly-once behaviour rather than a stream of duplicates during an outage. Failed endpoints are reported so a silently broken integration doesn't go unnoticed for weeks.
