Short answer

How can I use AI to test my Commerce.js checkout flow?

Your AI uses specific tools to build carts, modify quantities, and generate tokens for the final checkout step. This allows you to validate your store's logic by simulating a complete customer journey through chat. You'll see exactly how your cart handles different item combinations and updates.

Where every outcome lands.

Testing outcomes

The AI handles the heavy lifting of the transaction flow, leaving you to review the results.

VALIDATION

Verified cart states

The AI builds the cart and adds items to ensure the math and availability match your expectations.

LOGIC

Updated item counts

You can test how your store handles quantity changes or item removals by asking the AI to adjust the cart.

READY

Checkout tokens generated

The AI produces the final token needed to move into the payment phase, proving the flow works end-to-end.

HUMAN

Manual review needed

You decide when to stop the simulation or when to manually inspect the final checkout state in your dashboard.

The workflow

What your AI does when the request arrives.

The AI follows a sequence of API calls to mimic a user clicking through your store.

  1. Initialize the session

    The AI starts a fresh session by creating a new shopping container.

    create_cart

  2. Populate the cart

    The AI selects specific products from your catalog and places them in the session.

    add_to_cart

  3. Modify quantities

    The AI changes the number of items or removes specific products to test edge cases.

    update_cart_item

  4. Finalize for payment

    The AI generates the necessary token to transition the cart into a checkout state.

    generate_checkout_token

FAQ

How this task behaves.

  • 01

    Can the AI process actual credit card payments?

    No. The AI only generates the checkout token. You must handle the actual payment through your standard checkout interface.

  • 02

    Will the AI delete products from my store?

    No. The tools only interact with carts and checkout tokens. They cannot modify your product catalog or delete items from your database.

  • 03

    Can I test discount codes with the AI?

    The current tools focus on cart creation, item updates, and token generation. It does not have a tool to apply specific discount codes.

  • 04

    Does the AI see my customer's personal data?

    No. The AI only interacts with the cart and checkout logic as defined by the available tools.

  • 05
