Connect to Abacus and AbaConnect 

Maesn supports the Abacus REST API and SOAP-based AbaConnect WebServices for the Abacus business platform and industry-specific modules such as AbaBau.

Handling of Individual Base URL

Abacus doesn’t have a universal base URL. Instead, each Abacus instance is set up with its own unique URL. With Maesn, your customers enter the URL as part of the authentication process.

We provide you with everything you need, so you can focus on what counts.

  • You can read and write data in Abacus related to accounts, bank accounts, bills, invoices, credit notes, booking proposals, customer and supplier data, expenses, offers, payments, transactions, balances, journals, journal entries, projects and more. Learn more about how Maesn integrates to Abacus and AbaConnect.

  • In comparison to other Unified API vendors, you can always sync data when you want with Maesn. This can be done in real-time using webhooks or in your favorite interval like hourly, daily, weekly etc. 

  • Maesn Unified API acts as an abstraction layer above the Abacus REST API and the AbaConnect WebServices. That enables you to connect to Abacus and all industry-specific modules as AbaBau via Maesn.

  • ‍If a request fails, Maesn automatically responds with a corresponding error code. Further information can be found here

    You can monitor the status of your requests and resolve any errors using the Maesn Dashboard, which provides real-time observability and logs for better issue detection.

  • Setting up a Fortnox integration from scratch through Maesn typically takes anywhere from a few days to a few weeks, based on the complexity of your use-cases. The greatest thing is, once the integration is implemented, you can access more than a dozen additional accounting integrations, including DATEV, Exact Online, Qonto and Sage​​.

  • Maesn uses HTTPS for all data transfer. All connections are secured using TLS with industry-standard, state-of-the-art encryption.
    We don't store any of your customer data at Maesn to be 100% GDPR compliant - our platform is hosted at Microsoft Azure in Frankfurt, Germany.

  • Connecting Abacus via Maesn is faster, easier to maintain and the best thing: you get immediate access to dozens of other financial and ERP systems, while saving months of engineering effort spent on handling different APIs, Webservices, individual URLs and compliance edge cases across providers.
