A common use case for Finch APIs is to calculate YTD gross wages for individual employees. This useful and powerful information can be calculated easily by using the right approach.

​
Logic Flow

The general flow for calculating individual YTD wages works like this:
  1. Call the /payment endpoint and pass a start_date of the first day of the year (January 01) and an end_date of the current date.
  2. Loop over the array of returned payment objects and collect all of the payment ids.
  3. Call the /pay-statement endpoint and pass all of the payment_ids as a batched request.
  4. Loop over the array of returned pay statements and aggregate each individual’s gross pay amounts.
