Added Open to buy API
September 21, 2026
Balance APIs
Commercial and Consumer Secured Charge Programs
None
Overview
You can now retrieve the open to buy for a Security Account with the new Get Open to buy endpoint.
Open to buy is the overall program limi Lithic authorizes card spend against. The endpoint returns that amount together with the balances it is derived from, so you can see how much your end users can still spend across the program and why.
Details
- Only for Secured constructs with Security Accounts. If your program does not have a
financial_accountwith type =SECURITY, this API does not apply. - Calculated on request. Open to buy is not a stored balance. Lithic recalculates it on every request from three inputs:
- The available balance of the Security Account
- Funds that have moved out of the Security Account to cover settled card spend
- Authorized card spend that has not yet been collected from your business clients (outstanding spend)
