Frequently asked
questions

What is bexio?

bexio is a cloud-based accounting and business software platform widely used by SMBs and fiduciaries in Switzerland, offering tools for invoicing, bookkeeping, contact management, and more.

Why should I integrate bexio via Maesn instead of directly?

Integrating via Maesn eliminates all bexio-specific complexity. ID mapping, synthetic webhooks, and all bexio-specific implementation details are handled automatically behind one unified API. Plus, you immediately gain access to dozens of other accounting and ERP systems.

What is bexio's ID-based data model?

bexio uses numeric IDs instead of named object types throughout its data model. For example, a contact is not labelled as "customer" or "supplier", it is identified by a numeric type ID. Maesn resolves and maps all these IDs automatically into the Common Data Model, so you work with clean, named objects without any bexio-specific lookup logic.

Does bexio support webhooks?

bexio does not offer webhooks natively. Maesn fills this gap with synthetic webhooks, covering every object and every event in a normalized payload, consistent with every other system in your stack.

How does bexio authentication work with Maesn?

bexio uses OAuth for standard integrations and OpenID Connect for marketplace-listed apps. Maesn supports both authentication flows, so your integration is ready for direct use and bexio App Marketplace listing without any additional auth implementation.

Can I get listed in the bexio App Marketplace if I use Maesn?

Yes. The bexio App Marketplace gives your product direct access to bexio's SMB customer base in Switzerland. Requirements include more than 10 bexio customers, more than 20 active users, multilingual support in German, French, Italian, and English, and a signed marketplace partner agreement. Maesn supports you through the full qualification and listing process.

What data can I sync with bexio via Maesn?

Maesn supports invoices, bills, credit notes, customers, suppliers, contacts, payments, journal entries, expenses and more. Coverage is continuously expanding and endpoints can be added on demand.

What happens if a bexio API request fails?

Maesn automatically returns a corresponding error code. You can monitor the status of all requests and resolve errors in real time.

How is my customers' data handled and stored?

Maesn uses HTTPS and TLS for all data transfer and does not store any customer data. The platform is hosted on Microsoft Azure in Frankfurt, Germany, and is fully GDPR & ISO 27001 compliant.
