InFakt integrations - what can you connect in 2026?

In the world of digital accounting, it is no longer just about fast invoice handling but also about the ability to automate the entire sales and settlement process. inFakt has been developing its own API interface for years, allowing companies to connect their sales systems, online stores, and CRM programs with the accounting platform. Thanks to this, in 2026 invoice issuance, cost imports, and data synchronization between applications happen practically without human intervention. This solution is particularly important in the context of the mandatory KSeF — the electronic invoice system that comes into force for most companies in 2026. Automated data exchange with inFakt enables entrepreneurs to flawlessly send and receive e-invoices and monitor their status in real time.

How does the inFakt API work and why is it worth using?

The API interface in inFakt provides access to service resources via REST + JSON and enables automatic invoice issuance, payment monitoring, customer management, and data export/import to other systems. According to official inFakt data, over 1,200 companies already use the API, approximately 390,000 invoices are issued monthly, and the number of API requests reaches 26 million. KSeF connectivity can be configured directly through the API — the system supports sending multiple invoices simultaneously, importing income and cost documents, and checking their status. Additionally, inFakt provides webhooks that allow instant notifications about important events, such as receiving a payment or a change in invoice status.

Why are integrations crucial in 2026?

The year 2026 brings major changes to Polish accounting. According to the current schedule, from February 1, 2026 large companies will be required to use KSeF, while smaller enterprises will be covered by the obligation from April 1, 2026, with the exception of micro-businesses with turnover up to 10,000 PLN per month, which have until January 1, 2027. Integrations with inFakt allow entrepreneurs to prepare for this obligation, as they automate the process of sending e-invoices to KSeF and enable instant status checks. This helps avoid manual errors and meet tax office requirements without additional effort.

Automation with the Stripe gateway

More and more companies sell online and use the Stripe payment gateway. To automatically connect Stripe payments with settlements in Polish accounting systems, tools like striptu have been created. The striptu platform allows you to set up integration between Stripe and accounting systems (including Fakturownia, IFIRMA, wfirma, and inFakt) in just a few minutes. Thanks to this, after each Stripe payment, an invoice compliant with Polish law is created, and the entire process runs in the background without manual transaction export.

Summary

Integrations with inFakt in 2026 are not just convenience but a necessity for companies that want to meet the requirements of the new e-invoice system and grow their online sales. Connections with e-commerce platforms, CRM applications, and analytical tools make accounting fully automated. It is worth checking available integrations now, configuring the inFakt API, and preparing your business for the digital future.
