# Key ChargeGuard Objects

The data that Vindicia and you exchange for ChargeGuard is represented by objects in the Subscribe API. The most important objects for ChargeGuard are:

1. \*\*Transaction:\*\*The `Transaction` object encapsulates all transaction information, including the amount, payment method, associated customer account, and transaction status. (Most of this information is also provided to your payment processor.)

   The following Transaction information must be sent to Vindicia to provide evidence for disputes:

   * Transaction data fields
   * Item information
   * Rebill information
   * Payment method, including information on the credit card and the bank, if applicable
   * Customer information, including the customer name, billing address, and shipping address
     If post-transaction activity occurs, ChargeGuard can capture it for any subsequent chargeback disputes. Use the `Activity` object to notify Vindicia of your decision to complete, authorize to capture, or cancel the transaction.

2. \*\*Activity:\*\*The `Activity` object contains information about your interaction with a customer outside of the monetary transaction, such as a phone or email contact or a login to your site.

3. **Chargeback:** The `Chargeback` object contains information about a chargeback against a specific transaction, including the chargeback status provided by Vindicia during the dispute process.

4. \*\*Refund:\*\*The `Refund` object contains information about a refund from you to a customer for a specific Transaction. ChargeGuard applies partial and full refund data to transactions and to chargeback processing through the `Refund` object by associating the refund with the original transaction ID.
