System and API integration for business

System integrations are done by programmers, IT companies and small teams. techprojects.lt connects websites, online stores, CRM and accounting systems, such as Rivilė or B1, with payment and delivery services. We work remotely, in English or Lithuanian, with businesses in Lithuania and other EU countries. An integration costs from €100; we set the final price after assessing the scope.

Not always. For most business processes, a periodic transfer is enough, for example every hour or once a day. Real-time transfer is needed when a system must react to an event straight away, such as a paid order. We choose the method based on business needs, API capabilities, request limits and the acceptable data delay.

An API integration is a programmatic connection through which different systems automatically send and receive data by agreed rules. For example, an online store can pass an order to an accounting program, which returns the product's stock level. Nobody has to copy the data by hand, and transfer errors can be logged and monitored.

Not always. Integration is possible when the system has an API or another technical interface and clear documentation, and the necessary access rights are granted. Some providers limit the number of requests or apply extra conditions. Before we agree on the work, we check these points and tell you whether the integration can be done and what limits to expect.

Usually, yes. External systems change their API versions, authentication methods and data structures, so an integration that worked can stop transferring data. Maintenance covers error monitoring, notifications about failed transfers and fixes after provider changes. We agree on the scope of maintenance and the person responsible for it before launch.

A simple third-party system integration costs from €100. The final amount depends on the API documentation, the authentication method, the data fields, the transfer directions and exceptions. Once we have assessed the systems, we tell you whether changing settings is enough or programming will be needed, and we give you the price in writing before work starts.

The key ones are payment status notifications (webhooks), a test environment, refund handling and safe request retries that cannot create a double payment. The order number also has to travel through the whole chain, from the online store to the payment confirmation and the invoice in the accounting system. We check these capabilities in the provider's documentation before integrating.
