Short answer

How can I refund or void a payment using my AI?

You tell your AI to issue a refund or void a transaction, and it executes the command via Checkout.com. This handles both returning funds to customers and canceling pending charges. You'll see the specific outcomes for each request below.

Transaction outcomes

Where every correction lands.

Depending on the transaction state, your AI performs one of these actions.

REFUND

Return customer funds

The AI pushes money back to the original payment method. You get confirmation once the transaction is processed.

VOID

Cancel pending charges

If a transaction hasn't settled, the AI stops the funds from moving. This prevents the charge from hitting the customer's bank.

MANUAL

Human intervention needed

If a transaction is too old for a void or requires complex dispute handling, the AI flags it for you to handle in the Checkout.com dashboard.

LOG

Audit trail created

Every action taken by your AI is recorded. You can ask your agent to summarize what was corrected and when.

The workflow

What your AI does when a billing issue arrives.

Your AI acts as the interface between your chat window and the Checkout.com API.

  1. Identify the transaction

    Your AI looks up the specific payment details you provide to ensure it targets the right record.

    void_payment

  2. Execute the correction

    The AI sends the instruction to Checkout.com to return the money or stop the pending charge.

    refund_payment

  3. Verify the status

    The agent checks the response from the API to confirm the instruction was successful.

    void_payment

  4. Report the result

    You receive a plain text confirmation in your chat client showing the outcome of the request.

    No. Once a transaction has settled, you must use a refund instead of a void.

    No. The AI only has access to the tools provided, which are limited to refunding and voiding payments.

    No. The AI only performs the specific actions you tell it to do in the chat.

  • 04
