API integration and REST API development for CodeIgniter, Laravel, WordPress and Shopify. We connect your store, ERP, CRM, payment gateway, logistics partner and WhatsApp, and we have shipped Razorpay, Shiprocket, Unicommerce, HubSpot, Auth0 and Brevo integrations on live client platforms.
- Data flow mapped before any code
- Every event logged and retried
- Documented with Postman or OpenAPI
Integrations built by the team that builds the platform.
We write the CodeIgniter, Laravel, WordPress and Shopify code on both sides of the connection, so nothing is lost between two vendors.

Manual re-entry
The problem
Systems that should talk to each other, but do not.
Every manual step between two platforms is a chance for an error, a delay and wasted staff time. These are the six we remove most often.
02
Stock that does not match
The store shows units the warehouse no longer has. Overselling, manual corrections and unhappy customers follow.
Two numbersOne synced number
03
Customers not told when orders ship
Tracking updates sit on the courier portal, so customers message support every day to ask where their order is.
Support asksAuto WhatsApp
04
Failed payments nobody follows
A Razorpay webhook is missed, the order sits in limbo, the customer thinks they paid and nobody follows up.
Order in limboHandled event
05
Leads copied into the CRM by hand
Website enquiries are pasted into HubSpot every few days. Some are missed and sales work from a stale list.
Copy and pasteSynced on submit
06
An app with no link to your data
The website holds the data and the mobile app is a new silo, because a proper API between them was never built.
Two silosOne REST API

REST API design and build
A clean REST API on your CodeIgniter, Laravel or WordPress backend: versioned endpoints, consistent responses, correct status codes, rate limiting and API key auth.
Fixed price or time and material
Webhook integration
Events from Razorpay, Shiprocket, Shopify or any platform received, signatures validated, payloads parsed, actions triggered and everything logged.
Fixed price
ERP and inventory sync
Two-way sync between your store and ERP or warehouse system: orders out, stock in, shipment status back. Scheduled jobs or event driven.
Fixed price
OAuth2 and SSO
Auth0 OAuth2 with PKCE, JWT verification, role mapping from external data and rate limiting, for WordPress, CodeIgniter 4 and Laravel.
Fixed price
WhatsApp and notification APIs
WhatsApp Business API for order updates, OTPs and support, Firebase for push, and SMTP through Brevo for transactional email.
Fixed price or time and material
Legacy wrapper API
A REST layer around an older platform without a full rewrite, so apps, partners and tools can use its data. Often the first step in modernising.
Time and material or fixed price
How an integration works
One order, three systems, no copy and paste.
A typical store to ERP connection we build. Shopify sends the order to your server, your server checks it, reshapes it and passes it on, and every step is written to a log.
1. Event
An order is placed
Shopify fires an order webhook to your server the moment it happens.
2. Your server
Check, reshape, log
- Signature verified (HMAC-SHA256)
- Fields mapped to the ERP format
- Request and response logged
- Failures queued for retry
- An alert if retries run out
3. Downstream
Order pushed to the ERP
Customer told it is confirmed
Shipment created when packed
Example flow. The platforms and steps change with your stack.
Our approach
Integrations that do not break quietly.
Integration bugs usually come from assumptions made before any code is written. So we start with the data, test against real shapes, and make failures visible.
-
01
Before any code
Map the data flow
What goes where, what triggers what, how data is transformed and what happens when a step fails, drawn and agreed first.
- Trigger and target
- Failure path agreed
-
02
Build
Sandbox first
Payment gateways and logistics APIs have sandboxes. We build there and test with real order shapes, edge cases and failures before touching production.
- Real order shapes
- Edge cases tested
-
03
Run
Fail loudly, log everything
Every webhook and API call is logged with its request and response. Failed events are queued for retry, never silently dropped.
- Full request log
- Retry queue

Document the contract
Every endpoint documented: URL, method, body, response and error codes, in a Postman collection or Swagger file.
- Postman or OpenAPI
- Architecture notes
Security
Secure by default, not as an add-on.
An integration opens a door into your platform. Each of these standards is part of the build on every project, not an optional extra on the quote.
REST
JWT / RS256
OAuth2 + PKCE
HMAC-SHA256
Retry queues
OpenAPI
API keys
For machine-to-machine calls between your systems and partners.
JWT tokens
HS256 or RS256 signed tokens for endpoints a logged-in user calls.
OAuth2 with PKCE
The standard flow for single sign-on, with no secrets in the browser.
Signed webhooks
Inbound events checked with HMAC-SHA256 before anything runs.
Rate limiting
Limits on every public endpoint, so one client cannot flood it.
Audit logging
Who called what, when, and what came back, kept for debugging.
Case study
Auth0 single sign-on for financialdataexchange.org.
Members sign in once through Auth0, and their access on the WordPress site follows their contact record in HubSpot. Built as a custom WordPress must-use plugin.

JWT
What we built
- Auth0 OAuth2 with PKCE in a custom WordPress mu-plugin
- JWT RS256 verification against the JWKS endpoint
- Role mapping from HubSpot contact data
- Cookie-based state management and rate limiting
- A security audit after the build, with no critical findings
Documentation
Your next developer will not have to guess.
Every integration ships with documentation, so it can be maintained, extended or moved without us in the room.
Postman or OpenAPI
Every endpoint with URL, method, headers, body, response and error codes.

Not sure what your integration needs?
Describe what should be connected. We map the data flow, tell you the right approach and quote before we start.
FAQ
API integration questions, answered.
If your question is not here, describe what you need connected and we will advise on the right approach.
Yes. We start with a codebase audit to understand the architecture before writing any integration code. If the platform has no API, we can add a REST layer without touching the core application. If it has an API that is undocumented, we work out how it behaves and document it first.
Every integration we build has error handling and logging. Failed webhook deliveries are queued for retry, and API failures show up in your admin panel or trigger an alert instead of failing silently. For platforms that change their APIs often, we build version-tolerant handlers where possible and document the upgrade path.
Yes. We have connected Shopify to Unicommerce and Increff on live client platforms. Shopify webhooks push order events to your server, your server transforms them and sends them to the ERP API, and the ERP sends stock updates back on a scheduled sync. We handle the field mapping, transformation and failure handling.
API keys for machine-to-machine calls, JWT with HS256 or RS256 for endpoints a logged-in user calls, OAuth2 with PKCE for single sign-on, HMAC-SHA256 signature checks on inbound webhooks and rate limiting on every public endpoint. All of it is standard on every build, not an optional add-on.
Yes. Every integration ships with a Postman collection or a Swagger and OpenAPI specification covering each endpoint: URL, method, headers, request body, response shape and error codes. You also get a written document covering the architecture, the data flow, how failures are handled and the environment variables needed to run it.
No. Single webhook integrations are a standard engagement and start at ₹8,000. Share the webhook payload format and tell us what should happen when it fires, and we build, test and deploy it. Most single-webhook jobs are done in a 4 to 8 hour session.
CodeIgniter 4, Laravel, WordPress and Shopify. We write the code on both sides of the connection on these platforms, so changes to the store, the API and the integration can be made by one team instead of being passed between vendors.
Yes. A REST API between your existing web platform and a mobile app is one of the most common jobs we do. We design versioned endpoints, add authentication with JWT, OAuth2 or OTP, and document everything so the app developers, whether ours or yours, can build against it.

Moving From WooCommerce to Shopify: A Migration Checklist That Protects Your Rankings
Most of the risk in a WooCommerce to Shopify move is not the product data. It is the URL map, the things that were plugins and now have to be rebuilt, and in India the payment gateway, which does not come across at all.
