About Sequin
By Toolradar Team·
Sequin provides a real-time, bidirectional sync between various APIs (like Salesforce, Airtable, Hubspot) and your PostgreSQL database. It allows developers to interact with these APIs using standard SQL queries (SELECT, INSERT, UPDATE, DELETE), effectively turning complex API interactions into simple database operations. This eliminates the need to deal with API documentation, query parameters, rate limits, and pagination, significantly simplifying integration development.
The product is designed for engineering teams looking to accelerate their development cycles and reduce the complexity of building and maintaining API integrations. By abstracting API complexities behind a familiar SQL interface, Sequin enables faster problem-solving, quicker deployment of new features, and reduces time spent debugging API-specific issues. It's particularly beneficial for those who are already proficient in SQL and database management, allowing them to leverage existing skills for API integration.
