Your customers keep their employee data in whichever system they already bought - BambooHR, ADP, Workday, Paycom, or a smaller payroll provider. Your product needs the same employee record out of all of them. Bindbee sits between those systems and yours. You integrate once, against one API and one data model. Whichever system a customer connects, their data is normalized to a single schema before it reaches your code. ## Bindbee features `HRIS, ATS, LMS` - whether an employee record comes from Workday or as a [`File`](/get-started/connection-methods), it reaches you with the same fields and types. The full upstream payload stays available as `raw_data`. Whatever the unified model doesn't carry, you can map as a [`custom field`](/guides/extending/custom-fields). Your customers authorize through a `magic link` or an [`Embedded SDK`](/guides/sdk/embedded-sdk) in your product. Create an employee or push a deduction through the same API. ## Reading and writing data Most integrations start by reading: Bindbee pulls from the source system, normalizes it, and serves it through the unified API. See [Reading data](/guides/reading-writing/reading-data). Bindbee writes back too, through the same API and the same models. See [Writing data](/guides/reading-writing/writing-data), or [Reading & Writing Data](/guides/reading-writing/overview) for how the two fit together. **Your customer's system stays the system of record.** Bindbee reads from it and writes back to it; it doesn't replace it, and it doesn't run payroll. ## Where to next Prerequisites and the fastest path to your first API response.
