Finch has introduced the Provider Sandbox, a new feature that allows developers to test integrations with HR and payroll providers in a controlled environment, enhancing the existing API sandbox. This tool enables the simulation of live connections with providers like Gusto and Deel using demo and trial accounts, offering a realistic testing ground without the risks associated with using live customer data. The Provider Sandbox supports various providers such as Gusto, Deel, BambooHR, and Zenefits, allowing developers to test unique use cases and provider-specific nuances, such as field support and data management differences. Developers can modify data in their demo accounts, sync with Finch, and see changes through the Finch API, facilitating confidence in provider support for their applications. The sandbox also showcases advanced features like Finch Request Forwarding, which allows access to raw data from providers' native APIs, useful for applications requiring specific data not included in Finch's standardized model. The Provider Sandbox is free for developers, aiming to foster innovation without compromising data security.
