API Development and Integration Services
The same customer in four systems, and no two of them agree.
It usually starts small. A price that is right in the finance system and wrong on the website. An order that exists twice with different totals. Somebody on the team who re-types the same record every Monday, because that is quicker than explaining why it is wrong.
From the business side that is an irritation. From the engineering side it is a set of decisions nobody wrote down: which system owns the record, what happens when one of them is unavailable, and how a failed message gets noticed by you rather than by a customer.
We design and build the connections between your systems, and we make those decisions explicit. REST and SOAP where the platform leaves no choice, events and webhooks where timing matters, files where that is genuinely the right answer, and Model Context Protocol capabilities where an AI agent has to act on your systems rather than just read about them. The work runs from a single SaaS integration to enterprise estates with years of customisation. We are based in Maynooth, Co. Kildare, which puts Dublin and Meath within an easy morning, and we work with clients across Ireland, the UK and the United States.
Integration When the Caller Is an AI Agent
Almost every integration ever built assumed one kind of caller: another program, written by somebody who read the documentation once and then behaved the same way forever. An AI assistant does not behave like that. It decides at the moment of asking which capability to use, it has to know what an operation will do before it calls it, and it will call the same thing twice unless something stops it.
That changes what an integration has to carry. An endpoint returning a list is enough for a program that already knows what the list means. An agent needs the meaning as well: what this capability is for, what it is allowed to change, what it refuses to do, and what it leaves behind as evidence. The Model Context Protocol, usually shortened to MCP, exists to carry exactly that, which is why it has become the way assistants reach real systems instead of guessing at them.
We build both, often on the same estate. A REST or SOAP integration that holds up under load is ordinary work and we do it. When you want those same capabilities available to an assistant, we put an MCP layer in front of them, with four things that an API on its own does not give you.
A manifest, not just an endpoint
What the capability does, what it may change, what it will refuse, and who is accountable for it. An agent that can read this does not have to guess, and a person reviewing it can see what it was permitted to do.
Limits it cannot argue with
What it may touch, how much, how often, and which actions always go to a person first. Enforced outside the model, so no amount of clever phrasing gets around them.
A receipt for every action
Who asked, on what basis, what changed and what it cost, written as it happens. The record an auditor reads, rather than one somebody reconstructs from log files afterwards.
A way to switch it off
One action, no deployment and no code change. If a capability starts doing something you did not intend, stopping it is part of the design rather than an emergency.
Our research wing has published how we arrived at this, in two parts: why the established integration patterns break when the caller is an agent, and the six mistakes we see most often, worked through in two industries.
API Integration That Fits Your Existing Technology
You do not always need to replace your current systems. Often, the better solution is to make the software you already use communicate effectively.
We help businesses integrate:
- CRM and sales platforms
- ERP and enterprise systems
- E-commerce platforms
- Learning Management Systems
- Student Management Systems
- Microsoft and Google services
- Booking and scheduling platforms
- Marketing platforms
- Internal business applications
- Legacy systems
- Custom-built software
Depending on the systems involved, integrations can be real-time, scheduled, event-driven or file-based.
Our API Integration Experience
Our team has worked across both enterprise and SME environments, integrating cloud applications, established business platforms and highly customised systems.
CRM & Business Platforms
We have experience working with and integrating platforms including:
- Microsoft Dynamics 365
- Salesforce
- Zoho CRM and Zoho Bigin
- GoHighLevel
Our Zoho experience also includes Deluge, allowing us to build custom functions, workflows and business logic where standard configuration or integrations are not sufficient.
We can work with CRM APIs to automate lead creation, contact updates, data synchronisation, activity management and workflows between CRM and external systems.
Zoho Integrations & Deluge Development
Zoho often sits at the centre of a wider business ecosystem rather than operating on its own. We work with:
- Zoho CRM
- Zoho Bigin
- Zoho Bookings
- Zoho Campaigns
- Zoho Flow
- Zoho APIs
- Zoho Deluge custom functions
Using Deluge, APIs and supported connectors, we can extend Zoho workflows and connect Zoho applications with websites, booking systems, communication tools and other business platforms.
E-commerce & Website Integrations
Our experience includes integrations involving:
- Shopify
- WordPress
- Wix
- Kajabi
We have worked with API and webhook-based integrations where actions in one system trigger processes in another. Examples can include synchronising customer information, enrolments, orders, CRM records or other business data between platforms. We have also worked with Shopify webhooks for event-driven integrations.
Learning & Education System Integrations
Education systems are one of the areas where our team has particularly extensive integration experience. We have worked with platforms including:
- Canvas
- Moodle
- Blackboard
- Tribal EBS
- Quercus
- SITS
- CELCAT
These projects can involve more than a simple API connection. Education integrations often require multiple systems to exchange student, course, enrolment, timetable and other institutional data while maintaining the correct identifiers and business rules.
Our experience includes Canvas APIs and webhooks, as well as integration patterns involving student management and learning management platforms.
Enterprise & Business System Integration
Our wider enterprise integration experience includes systems and environments involving:
- SAP
- Microsoft Dynamics 365
- Microsoft 365
- Salesforce
- INTTRA / Maerskline
These projects have given us experience working with complex business processes, existing enterprise architecture and systems that may have significant customisation already in place.
That matters because integrating an established enterprise platform is very different from connecting two new SaaS applications. We first need to understand the existing data model, business rules, authentication, customisation and integration dependencies before introducing new interfaces.
More Than REST APIs
Not every integration uses the same technology. We work with a range of integration methods depending on what each system supports.
REST APIs
REST APIs are widely used by modern cloud applications and SaaS platforms. We can work with existing REST APIs or design APIs for custom applications where required.
SOAP Web Services
Many established enterprise and institutional systems still rely on SOAP services. Our integration experience includes both REST and SOAP-based services, allowing us to work across modern and legacy environments.
Webhooks
Where platforms support them, webhooks can provide near-real-time communication between systems. Instead of repeatedly checking whether something has changed, the source system can notify another application when a particular event occurs.
CSV & File-Based Integration
Not every system provides a modern API. We also work with CSV files, scheduled file transfers and SFTP. File-based integration remains common in enterprise, education and legacy environments and can be a perfectly appropriate solution when designed correctly.
Authentication & Secure API Access
Security is an important part of API integration. Our experience includes working with authentication mechanisms such as:
- OAuth 2.0
- Basic Authentication
- API keys and tokens
We have worked with OAuth-based integrations including Microsoft Dynamics 365, where authentication and permissions form an important part of the overall integration architecture.
Custom API Integration
Sometimes the API exists, but the integration you need does not. We can build custom integration logic between platforms, including:
- Mapping data between different formats
- Transforming data before it reaches the destination system
- Creating or updating records
- Handling duplicate records
- Matching records using business identifiers
- Scheduling synchronisation
- Responding to webhook events
- Managing authentication
- Handling API errors and retries
- Logging integration activity
- Supporting custom business rules
The objective is not simply to make two APIs communicate. The integration needs to reflect how your business actually works.
Complex Integration Projects
Some projects involve a single connection. Others involve several systems where data needs to move through an entire business process. For example:
For complex environments, we look at the complete architecture rather than building isolated integrations that may create problems later.
Why Aitina Tech?
Enterprise Integration Experience
Our experience includes large enterprise and institutional systems as well as modern SaaS platforms.
SME Integration Experience
We also work with smaller businesses that need practical integrations between websites, CRM, bookings, marketing and operational systems without unnecessary complexity.
Integration & Architecture Together
API integration decisions can affect performance, security, scalability and maintainability. Because our experience extends into software architecture and cloud architecture, we can consider the wider technical environment rather than treating the API as an isolated connection.
Ireland-Based, International Delivery
Aitina Tech is based in Ireland and works with clients in Ireland and the United States, while supporting projects internationally.
Questions we get asked about integration
What does an API integration project actually involve?▼
First, deciding which system owns each record and what should happen when two of them disagree. Most integration pain turns out to be a decision nobody made rather than a technical problem. Then the build: the interface itself, authentication, retries, error handling and alerting, so that a failure is noticed by us and not by your customer. Then a handover you can maintain, with the design written down.
Can you connect our website or online store to the systems behind it?▼
Yes. Orders into the finance or ERP system, stock and prices back out, customers into the CRM, and the fulfilment and notification steps in between. Shopify, WordPress, Wix and custom storefronts are all common, and the shape of the work is much the same: decide where the truth lives, then make everything else follow it.
What is MCP, and do we need it yet?▼
The Model Context Protocol is how an AI agent is handed a capability it can use safely: a description of what the operation does, what it may change and what it must refuse. You need it when you want an assistant to act on your systems rather than only answer questions about them. If that is a next-year problem, the sensible move now is to build integrations that could carry a manifest later, which costs nothing extra at design time and saves rebuilding them.
How long does an integration take, and how do we find out what it will cost?▼
It depends on how many systems are involved and how much of the business logic is undocumented, which is why we do not quote from a list of features. Start with a free hour with one of our architects. You describe the systems and what has to stay in step, and you leave with a candid read on the effort and the risks, written down, whether or not you go any further with us.
Need to Connect Your Systems?
Whether you need to integrate two applications, connect a new platform to an existing system or design an integration architecture across several business applications, we can help you determine the most appropriate approach.

APIs join systems that are going to stay separate. When they are not, there is a simpler answer: Nexcubator is one platform for the whole business, so the work that would have crossed an API never leaves the system.
