This release introduces Pricing Groups — a new resource for managing interest rates at scale across your accounts. Instead of updating rates on individual accounts one at a time, you can now define reusable rate tier structures and assign them to multiple accounts. When a group’s rates change, all assigned accounts are updated automatically.

Fall updates are here! See below for our latest API changes.

This release adds depositor update support, account monthly statement configuration, tiered interest rates on accounts, and a batch of new optional fields across account and depositor schemas. We’ve also expanded the StatementType enum to cover a wider range of institutional reporting needs.
