Payment gateway integrations for eCommerce

Integrate payment providers with careful handling of authorisation, capture, refund, cancellation, webhooks and the order states that surround each transaction.

What this service covers

Payment integrations built around the way your business actually works

Good payment integrations is not a collection of isolated development tasks. It needs to fit the commercial model, operational workflow, existing systems and the people responsible for running the platform every day.

We start by understanding the current environment, the business outcome you are trying to achieve and the constraints that matter. That creates a clearer technical plan and reduces expensive rework later.

Checkout integration

Create a customer payment flow appropriate to the provider and checkout experience.

Payment state

Map provider states to Magento/order states without leaving ambiguous or duplicated transactions.

Webhooks & callbacks

Process asynchronous provider events safely and idempotently.

Refund & operations

Support refunds, cancellations and operational investigation with clear transaction references.

Delivery

What we can take responsibility for

Midoriweb can work as the primary technical partner, add specialist capacity to an internal team, or take ownership of a defined workstream. The engagement model can change as the requirement evolves.

The emphasis is on maintainable implementation, transparent communication, documentation and testing so the work can continue to be supported after launch.

Technical depth

Engineering decisions that survive real-world use

Production systems behave differently from prototypes. Catalogue size, integrations, traffic patterns, background jobs, deployment processes, data quality and third-party dependencies all influence reliability.

We design around those realities from the beginning and make performance, security, observability and supportability part of the solution rather than afterthoughts.

Frequently asked questions

Questions we are often asked

Can this connect to Magento Open Source?

Yes. Magento is a common endpoint, but the integration can also connect custom applications and other systems.

Do you support both APIs and file-based integration?

Yes. The right approach depends on the capabilities and constraints of the systems involved.

How do you handle failures?

We design logging, retries, idempotency and a manual recovery route appropriate to the workflow.

Can you replace a manual process gradually?

Yes. Automation can be introduced in stages so the operational team retains control while confidence grows.
