Connect the tools your business already uses.
Your website should not be an isolated island. We build clean, secure API integrations and webhook bridges that connect your digital storefront to payment platforms, CRMs, Google services, email dispatchers, and internal company databases.
Connecting Your Business Ecosystem
We design custom API middleware that synchronizes data bi-directionally with high reliability.
Payment Gateways & Direct Pay
Seamless Razorpay, Stripe, and UPI payment flows with verified webhook receipts and zero middleman commissions.
CRM & Lead Management
Synchronize client inquiries directly into HubSpot, Zoho CRM, Salesforce, or automated Google Sheets tables.
Transactional Email & SMS
Reliable transactional notifications via Resend, Postmark, AWS SES, or Twilio with high inbox deliverability.
Custom Webhooks & Event Listeners
Real-time event processing with signature verification, automatic retries, and dead-letter queues.
Google Cloud & Maps Services
Geocoding, route calculation, Places API, and Google Workspace calendar synchronizations.
Internal Databases & ERPs
Secure middleware bridges connecting public storefronts to private PostgreSQL, MySQL, or enterprise databases.
HMAC Signature Verification & Idempotency
Every incoming webhook is verified cryptographically before execution. Database transactions are engineered with idempotency keys, guaranteeing that duplicate network packets never produce duplicate charges or records.
Frequently Asked Questions
What is an API integration and why does my business need one?
An API integration allows your website or custom application to communicate securely with external platforms—such as synchronizing orders with accounting software, dispatching CRM leads, or processing credit card/UPI payments in real time.
Which payment platforms can INNISHA integrate?
We integrate official payment providers including Razorpay, UPI QR rails, Stripe, and Cashfree, implementing secure server-side webhook verification and idempotent transaction handling.
Can INNISHA connect legacy or internal business systems?
Yes. If your internal database or software supports REST APIs, SFTP, webhooks, or SQL connections, we can architect secure middleware to bridge your public website and internal systems.
How is data security handled during integrations?
We enforce HTTPS transport security, cryptographic webhook signature verification (HMAC SHA-256), encrypted secret management, and minimal permission scopes for all third-party API keys.
Have third-party tools that need to communicate?
We connect your business platforms with clean, robust API engineering.
