New Tax & Agency Reference APIs

This is available now in Sandbox and Live environments. See the Tax and Agency API references for full details.

This is the first of a consistent set of tax, agency, and jurisdiction references we'll use across the API, so you can increasingly group and reconcile tax activity the same way everywhere.

This makes migrations easier: resolve a prior system's tax codes to Check taxes and keep them current as the catalog changes. You can also filter by supported to see which taxes Check calculates.

You can now read Check's tax catalog directly from the API. Two read endpoints surface the taxes and agencies Check works with. Both use a canonical lowercase jurisdiction code (fed, ny, pa) so you can filter by region.
