How to Use the UnionPay Open Platform MCP in Claude Code

Q: How do I manage payment flows with UnionPay Open Platform using Claude Code?

You write a shell script that calls initsecurepayment. Since it's terminal-only, the output is piped directly into subsequent tools or logged for auditing.

Q: Can UnionPay Open Platform assist with monitoring transactions in CI/CD?

Absolutely. Your pipeline can use getqrtransactionstatus in a loop to poll for payment finality, ensuring the CI job doesn't fail just because the transaction takes time.

Q: How do I integrate UnionPay Open Platform with Claude Code for token management?

Use requestcardtoken to create the secure record. When done, your script calls cancelcardtoken. This is a clean way to manage credentials in a headless environment.

Execute global payments and card processing from the terminal with Claude Code.

Process Payments in CI/CD Pipelines

You can write a shell script that initializes a secure payment session using `init_secure_payment`. This is perfect for automated, non-interactive checkout testing. Need to process an in-person transaction? Your pipeline runs `generate_qr_code` and then monitors the result with `get_qr_transaction_status`, all via standard output.

Automate Card Tokenization

Write a command that calls `request_card_token`. This securely tokenizes card data, allowing subsequent payment steps in your deployment script. If the system needs to decommission a token, simply run the command invoking `cancel_card_token` to unbind it from the platform.

Verify User Credentials and Risk Status

Before running any payment job, your script must call `verify_card_kyc`. This confirms both identity status and card binding. It's a critical prerequisite. You can also pipe the result of `check_card_risk_status` into another tool to gate whether the transaction should proceed.

Setup guide

Common questions about UnionPay Open Platform MCP in Claude Code

You write a shell script that calls `init_secure_payment`. Since it's terminal-only, the output is piped directly into subsequent tools or logged for auditing.

The server handles verification of identity and card binding. This involves processing personal identification details and linking them to the physical card numbers provided during `verify_card_kyc`.

Absolutely. Your pipeline can use `get_qr_transaction_status` in a loop to poll for payment finality, ensuring the CI job doesn't fail just because the transaction takes time.

Use `request_card_token` to create the secure record. When done, your script calls `cancel_card_token`. This is a clean way to manage credentials in a headless environment.

Since you're running headlessly, ensure the script captures all necessary output from `generate_qr_code` and that the environment variables holding client credentials are properly passed to every MCP call.
