What is Halocard Virtual Cards?
Halocard is a specialized tool designed to facilitate secure financial transactions within autonomous workflows. It allows agents to generate disposable virtual credit cards specifically for checkout processes, such as ordering supplies, purchasing subscriptions, or booking services. By acting as a secure payment bridge, it ensures that your primary financial details remain protected while enabling Openclaw Skills to complete end-to-end commerce tasks.
This skill is not intended for standalone use but rather as a critical payment step in a larger automation sequence. It focuses on high-security standards, requiring explicit user confirmation before any card creation and ensuring that sensitive card data is never permanently stored or logged, maintaining a high level of privacy and control for the user.
Halocard Virtual Cards Use Cases
- Automating food delivery orders through services like Uber Eats or DoorDash.
- Managing software-as-a-service subscriptions by generating dedicated cards for each vendor.
- Purchasing domains or hosting services as part of a DevOps deployment workflow.
- Completing retail checkouts for physical goods during browser automation tasks.
How Halocard Virtual Cards Works
- The agent navigates to the merchant's checkout page as part of a broader user request.
- The system extracts the exact total amount from the page to prevent estimation errors.
- A summary of the merchant, items, and total cost is presented to the user for explicit approval.
- Once approved, the agent sends a POST request to the Halocard API to create a single-use card for the specific amount.
- The agent automatically fills the credit card fields (PAN, CVC, Expiry) on the payment form.
- After submission, the agent verifies the order confirmation and reports the success back to the user.
Halocard Virtual Cards Setup
To enable Halocard, you must configure your API token in your environment.
- Sign up for a Halocard account at https://secure.halocard.co/enter.
- Retrieve your API token from the Halocard Dashboard.
- Set the token as an environment variable:
export HALOCARD_TOKEN="your_token_here"
