    What is API Development & Integration?

    API development is the work of designing, building, securing and documenting the contracts that let two pieces of software talk to each other reliably. It includes your own internal APIs, public developer APIs and integrations with tools like Razorpay, Shopify, HubSpot and many more.

    We design APIs the way the best product companies do: contract first in OpenAPI, versioned, rate limited, monitored and well documented so your partners and frontend developers love working with them.

    Why this matters for your business

    APIs are how your product becomes a platform. Clean, well documented APIs reduce integration support tickets, attract partners and let your own teams ship faster.

    Who actually needs this

    Does this sound like you?

    You are about to expose a public API to partners or customers and want to do it right.
    Your current API is a tangled monolith and every change breaks something.
    You need to integrate with several SaaS tools and the in-house attempt has stalled.
    You are moving toward microservices and need someone who has done it before.

    Questions you should actually ask

    Honest answers to the things every buyer asks us in the first call.

    REST is best for public APIs and simple resources. GraphQL is great when frontend teams need flexible data fetching from many sources. Often we use both for different jobs in the same product.
