Secure File Transfer Protocol (SFTP) is widely used for bulk data transfers, but its scalability is limited due to the complexity and manual processes involved in setting up and managing connections. This can result in lengthy onboarding processes, increased strain on internal teams, and hindered business growth. Unified APIs offer a solution by reducing onboarding times and standardizing data from multiple sources, allowing for easier automation of routine tasks and more efficient operations. These APIs can transform SFTP connections by standardizing data formats, providing a single setup process applicable to multiple clients, and automating previously manual processes. Solutions like Finch Flatfile further simplify scaling SFTP integrations by offering automated data delivery and standardized formatting without significant engineering investments, thus enabling companies to maintain lean teams while boosting operational efficiency.
