Sequin offers a solution for integrating Stripe data into applications by allowing developers to build apps and workflows using SQL and Postgres, with seamless synchronization between APIs like Stripe and a database. This approach addresses challenges when an app's functionality relies on data from both Stripe and the app's database, such as displaying user-specific content based on subscription status. The text explores methods to manage Stripe data, including querying the Stripe API directly, maintaining a local copy of the data, and using Stripe's webhooks. Each method has its pros and cons, such as API rate limits, the complexity of webhook management, and the difficulty of maintaining a real-time database. Sequin simplifies this by enabling real-time data synchronization without extensive development, providing a scalable and flexible solution for integrating Stripe data into applications.
