Which systems can you integrate?

Anything with an API, and some things without one. We have worked with Stripe, Razorpay, Cashfree, HubSpot, WooCommerce, Shopify, Square, Firebase, Google Maps and telephony providers, among others.

Should we use Zapier or Make instead?

For low volumes and simple flows, often yes, and we will say so. Custom integration is worth it when volume makes per-task pricing expensive, when you need error handling those tools cannot give you, or when the logic is too involved to maintain in a visual builder.

What happens when the other system goes down?

Events are queued and retried, and nothing is lost. If retries are exhausted the event is parked where a person can inspect and replay it, and someone is alerted.

Can you fix an integration somebody else built?

Yes. We start by adding logging so we can see what it is doing, then fix the failures in order of how much damage they cause.

Integrations & APIs

Make your systems work together.

Businesses rarely run on one system. Orders live in the store, customers in the CRM, invoices in accounting, and people move data between them by hand. We build the connections: well-designed APIs for your own software, and dependable integrations with the third-party systems around it.

You might be here because

The same customer record is maintained by hand in two or three places.
Your Shopify store and your ERP disagree about stock.
A partner needs API access and you do not have an API.
An integration someone built years ago fails silently and nobody knows why.

API integration services and custom API development

API development: Documented, versioned REST and GraphQL APIs for your product or platform.
API integrations: Connections to third-party services, with retries and error handling built in.
CRM integrations: HubSpot, Salesforce, Pipedrive and others kept in step with your own systems.
ERP integrations: Orders, inventory and finance data moving between the ERP and everything else.
Shopify integrations: Custom apps, storefront logic and back-office sync beyond what plugins offer.
Payment integrations: Stripe and other providers: subscriptions, marketplaces, invoicing and payouts.
Accounting integrations: Invoices and payments posted to Xero, QuickBooks and similar tools.
Data synchronization: One-way or two-way sync with clear rules for which system wins.
Webhooks: Event delivery in and out, verified, queued and replayable.
Custom integrations: Connections to systems with awkward, old or undocumented interfaces.

What this looks like in practice

Payments, payouts and refunds

Loyla uses Stripe Connect so shops are paid out directly. Turanta and Jharkhand Fresh run on Razorpay and Cashfree.

Three storefronts, one back office

Tru-Scapes Command Center pulls orders, products and stock from three stores into one system and syncs with HubSpot.

A store that updates the back office by itself

A typical project: orders flow from the storefront into the ERP and accounting system, and stock flows back.

How we approach it

We map the data first: which system owns each field, and what happens on conflict.
Integrations are built to fail loudly, with alerts, logs and a way to replay events.
Credentials and tokens are stored properly, never in code.
You get documentation a future developer can actually follow.

Third-party API integration that survives production

Calling an API is the easy part. Integration projects go wrong in the moments around the call: the other system is down, a request times out and is sent twice, a webhook arrives out of order, or the provider changes a field without notice.

We design for those moments from the start, with queues, retries, idempotent writes, verified webhooks, logging and a way to replay failed events.

Custom API development for your own product

When partners, customers or your own mobile app need access to your system, the API becomes a product in its own right. It needs authentication, versioning, rate limits, clear errors and documentation someone can follow without calling you.

We build APIs to that standard, usually in NestJS, and document them so that the next integration does not need us in the room.

Connecting stores, CRMs, ERPs and payment systems

Most integration work is a business problem expressed in data. Which system owns the customer record? Which one is right about stock? What happens when they disagree?

We answer those questions in writing before building. For Tru-Scapes we are connecting three storefronts and HubSpot into one back office. Loyla’s backend accepts orders from Square, Shopify, Epos Now, Lightspeed and SumUp tills.
