Bolt Financial Transactions API is one of 13 APIs that [Bolt Financial](https://apis.io/providers/bolt-financial/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Transaction. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Use the Transactions endpoint to authorize payments when the shopper checks out and handle post authorization actions such as captures and refunds. You can use a shopper's existing saved payment information or tokenize new payment information with the [Bolt Tokenizer](https://help.boltapp.com/api-tokenizer/). Bolt Authorize Transaction types fall into one of three categories: a logged-in shopper checking out with a saved payment method, any type of shopper checking out with a new payment method, and a logged-in shopper checking out with a new payment method. The new payment method will be saved to the shopper's account.
