Blog post from Unified.to
Integrating with the Stripe API allows developers to handle a range of payment-related functions such as processing payments, managing subscriptions, creating invoices, issuing refunds, and synchronizing billing data. The integration process involves understanding Stripe's REST API model, authenticating requests using API keys, and designing for idempotency to ensure safe retries. Developers must manage various complexities, including webhook reliability, multi-account platforms like Stripe Connect, and pagination across large datasets. While direct integration with Stripe offers full control over PaymentIntent flows and advanced billing features, using a service like Unified can provide a normalized integration layer that reduces maintenance and abstracts complex tasks like webhook handling. This guide covers when to choose direct integration versus leveraging an integration layer like Unified, emphasizing the importance of handling operational complexities from the outset.
