The proliferation of SaaS companies, now exceeding 30,000 globally, has led to a surge in B2B integrations, primarily to meet the demand for interconnected applications. Businesses subscribing to multiple SaaS products expect seamless integration between apps, prompting SaaS companies to either create bespoke integrations or utilize embedded integration platforms. Key integration patterns include event-driven, scheduled, synchronous, and hybrid approaches, each with its own benefits and challenges. Event-driven integrations, the most prevalent, use webhooks or pub/sub systems to trigger data exchanges, while scheduled integrations rely on time-based triggers. Synchronous integrations require immediate data retrieval and response, often facing challenges like network delays. Hybrid integrations combine multiple patterns to accommodate varying system capabilities. Platforms like Prismatic facilitate the creation, deployment, and management of these integrations, offering flexibility and enabling SaaS companies to productize their integrations for diverse customer needs. Understanding these patterns is crucial for effectively planning and executing integration projects.
