API Integration
API Integration & Custom API Development
Connecting websites and apps to payment gateways, CRMs, ERPs and third-party services, plus custom REST and GraphQL APIs.
API Integration by Narayana Web Solutions
Narayana Web Solutions connects your website, online store and business software so data flows automatically between them. We integrate third-party APIs — payment gateways, CRMs, ERPs, marketing, shipping and accounting tools — and build custom REST and GraphQL APIs for your own products and partners.
Good integrations remove double data entry, reduce errors and give you one reliable view of your business. We build them to be secure, well documented and resilient when external services change or go down.

API Integration FAQs
What is API integration?
API integration connects two or more software systems through their application programming interfaces so they can share data automatically — for example, sending website orders to your accounting software or new leads to your CRM.
Which payment gateways can you integrate?
We integrate Stripe, PayPal, Razorpay and most other payment gateways that provide an API, including one-off payments, subscriptions, refunds and webhooks for payment events.
Can you connect my website to my CRM?
Yes. We connect websites and online stores to CRMs such as HubSpot, Salesforce and Zoho so form submissions, customers and orders sync automatically.
Can you build an API for my own product?
Yes. We design and build secure, versioned REST and GraphQL APIs with authentication, rate limiting and documentation for your apps, partners or customers.
What happens if a third-party API changes?
We build integrations with monitoring and error handling so problems are detected quickly, and our maintenance plans include updating integrations when providers release new API versions.
