Connect Adyen and Medius

Connecting Adyen and Medius for a company could allow payment transaction data from Adyen to be transferred into Medius for reconciliation or accounts payable processes. This connection could support more efficient financial workflows by reducing manual entry and improving the accuracy of financial records between payment processing and invoice management systems.

You can build this integration on the System2System platform. We design the connection between Adyen and Medius around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect Adyen and Medius?

A company operating both Adyen and Medius could benefit from connecting these systems to enable more efficient and reliable data exchange between payment processing and financial management functions. Without such a connection, teams may need to manually enter transaction details from Adyen into Medius, increasing the risk of errors, duplicated records, and delays. This manual approach can result in data inconsistencies, where payment statuses in Adyen do not match those reflected in Medius, making it harder for finance teams to reconcile accounts and for decision makers to act on up-to-date information. Common data exchanged between systems of these types could include payment transaction details, settlement reports, and invoice statuses. The actual scope of what can be exchanged depends on what each system exposes through its API, and is determined per situation.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what Adyen and Medius make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
