# Overview

> Financial activity for registrants — payments, refunds, and credits

Transactions record financial activity for registrants — payments, refunds, and credits. The API supports offline payment types (credit card, wire transfer, check, cash, etc.) and integration with payment gateways.

## What you can do

* **Record payments** for offline transactions (check, cash, wire transfer)
* **View transaction history** for any registrant
* **Delete erroneous transactions** to correct financial records

## Key concepts

**Offline payments** — The create endpoint is primarily used for recording offline payments (e.g., a check received in the mail). Online payments processed through Swoogo's payment gateway are recorded automatically.

**Transaction types** — Transactions can represent payments, refunds, or credits, each affecting the registrant's balance differently.
