When your user runs a payroll, the necessary accounting transactions are automatically created in the user's General Ledger. Furthermore, when the bank withdrawals come in several days later, the Tight API will automatically reconcile those with the payroll run, keeping the user's General Ledger and balance sheets in sync, without any manual labor required from your user. That reconciliation process, when done manually, can be very complex, as a single Check payroll run and the subsequent withdrawal need to be split over many different accounts. With the Tight API, this reconciliation happens automatically, without user input. See the [**Monthly Payroll Run Example**](/guides/business-owners/payroll#monthly-payroll-run-example) to understand the level of complexity that Tight automates. ## Get Started ### Configure Check Integration If you haven't already done so, you should create a developer account with Check at [checkhq.com](https://checkhq.com/). Once you're logged into Check's Dashboard, navigate to the API Keys section to access your credentials. Check Config ### Securely share your Check keys You should then copy your `Key ID`, this can be programmatically provided to the [Configure Check API](/api-reference/integrations/configure-check). For production deployment, repeat these steps using Check's Live mode toggle.
