API Integrations

Your CRM doesn't talk to your payment gateway. Your legacy system doesn't talk to your new app. We build the connections that make separate systems function like one. That's ranged from wiring in a single payment gateway to building middleware that keeps a dozen systems in sync in real time. We built the payment, SMS, and fundraising integration for an NGO's donation platform: three separate third-party systems that had to work together seamlessly for a donor completing a transaction. Every integration is designed around what happens when a call fails, not just when it succeeds, because that's the part most integrations skip.

Overview

Built for what happens when a call fails

Most of the systems a growing business already runs were never built to talk to each other. Payment gateway, CRM, inventory, SMS provider: each has its own API, its own auth model, its own way of failing. Wiring them together properly, so a failure in one doesn't quietly corrupt data in another, is the actual work.

Scope can be as small as a single gateway or as large as middleware holding a dozen systems in sync in real time. Either way, we design around the call that fails, not just the one that succeeds.

What's Included

What you get with API Integrations

Payment gateway integration

Stripe, Razorpay, PayPal, and regional gateways, tested against real failure cases.

SMS & communication gateways

Transactional and marketing messaging wired in reliably.

Third-party API integration

CRMs, ERPs, and external services connected properly.

Custom middleware

When systems need translation logic between them, not just a direct call.

Failure handling & retries

What happens when the other system is down: planned for, not discovered in production.

Digital signature & e-sign integration

Legally binding digital signature workflows wired into your systems.

How We Work

Our approach

Clear stages, visible progress, and ownership that continues after launch.

01

Discovery

We map requirements, existing systems, and risk before a line of code moves.

02

Architecture

Technical planning and trade-offs explained in plain language: you decide, we advise.

03

Development

Sprints with visible, working progress, demos over status meetings.

04

QA & Validation

We prove it works under real conditions before anything reaches your users.

05

Deployment

A controlled release with a rollback plan, so launch day stays uneventful.

06

Support

Continuous improvement after launch, because the work isn't done when the ticket closes.

FAQ

Common questions about api integrations

Can you integrate with a system that has no public API?

Sometimes, through other means: screen scraping, file-based transfer, or database-level integration. We'll assess feasibility honestly.

What happens if a third-party API goes down?

We design retry logic and failure handling up front. Your system should degrade gracefully, not silently lose data.

Do you document the integrations you build?

Yes, so your team, or the next vendor, understands what's connected to what.

Can you integrate payment and SMS gateways together, like for a donation platform?

Yes, we've built exactly this: payment, SMS, and fundraising systems working together for a nonprofit's donor platform.

Can you build middleware to keep multiple systems in sync?

Yes, when a direct point-to-point connection isn't enough, we build middleware that handles translation and sync logic between systems.

Do you support GraphQL as well as REST?

Yes, we'll recommend whichever fits the systems involved and your team's existing tooling.

Whether you need a brand-new build, a redesign of something that's already live, or a second opinion on a project another vendor left behind, our in-house engineering team scopes the work honestly, keeps you updated sprint by sprint, and stays reachable after launch instead of disappearing once the invoice is paid. Fill in the quick form and we'll reply within one business day, or book a free 30-minute architecture review if you'd rather talk it through first. No obligation, no sales pitch.
