While file storage integrations can be complex and challenging, many SaaS companies struggle due to the complexity of APIs from Google Drive, Microsoft 365, Dropbox, OneDrive, and SharePoint. Common issues include app verification delays, account type differences, handling large files, real-time updates, recursive structures, efficient file change detection, unstructured data retrieval, complete file listing, token rotation, and authentication. Each cloud storage service has its unique challenges, such as Google Drive's API rate limits, Dropbox's version history, SharePoint's complex API, OneDrive's Graph API integration, and Box's enterprise security requirements. However, Integration.app provides a solution to build integrations with these services in 30 minutes or less, by offering an API-first and fully customizable service, pre-built scenarios, and pre-built UI components.
