Practice

APIs & Integrations

Dependable connections between the systems your organisation runs on. Well-documented REST APIs, payment gateways, ERP synchronisation and messaging platforms, engineered with retries, logging and transparent error handling.

  • 5 engagements
  • From ₹18,999, GST incl.

Why this practice

Every manual re-key between two systems is an error waiting to be found by a customer. These engagements connect systems properly, with retries, idempotency and somewhere to look when a message fails.

Connections that stay connected

Documented endpoints, sensible retries, and failures that surface in a log instead of a spreadsheet.

  • The fee is published on each engagement page, GST included
  • Deliverables and exclusions are written down before you check out
  • Code, accounts and documentation stay in your organisation’s name
