Overview

API Integration Services — done the right way.

Most digital businesses run on APIs. We integrate third-party APIs into your website, mobile app, CRM or portal — cleanly, securely and with proper error handling, so transactions don't fail silently. Whether you need recharge and BBPS bill payments, flight and hotel booking, PAN, bank account or GST verification, a payment gateway, WhatsApp and SMS, courier tracking or GST e-invoicing, we read the documentation, build the integration, test every edge case and hand it over with logs and monitoring.

Almost any documented REST or SOAP API — recharge, BBPS, travel, KYC and verification, payment gateways, SMS, WhatsApp, email, shipping, GST, accounting and CRM APIs.

Simple integrations start from ₹9,999. Complex multi-step flows (booking, wallets, reconciliation) are quoted after we review the API documentation.

We integrate the API provider you choose, or recommend reliable providers. You sign up with the provider and own the account and credentials.

Yes. We audit existing integrations, fix failed or stuck transactions, and add logging and reconciliation.
