Credit card credentials store payment details so the AI can fill checkout forms without you embedding card numbers in prompts or parameters. Like all credentials, card numbers never reach the LLM. They are injected directly at the browser level.

​
Creating a credit card credential

Use the POST /v1/credentials endpoint to create a credit card credential: 
from skyvern import Skyvern

skyvern = Skyvern(api_key="YOUR_API_KEY")

credential = await skyvern.create_credential(
    name="Corporate Visa",
    credential_type="credit_card",
    credential={
        "card_holder_name": "Jane Doe",
        "card_number": "4111111111111111",
        "card_brand": "visa",
        "card_exp_month": "12",
        "card_exp_year": "2025",
        "card_cvv": "123"
    }
)

print(f"Created credential: {credential.credential_id}")
# Output: Created credential: cred_1234567890
Response: 
{
  "credential_id": "cred_1234567890",
  "name": "Corporate Visa",
  "credential_type": "credit_card",
  "credential": {
    "last_four": "1111",
    "brand": "visa"
  },
  "browser_profile_id": null,
  "tested_url": null
}
After saving, the card number is masked and only the last four digits are ever returned. Sensitive fields (full card number, CVV, expiration, cardholder name) are never included in API responses.

​
Supported card brands

Skyvern supports all major card networks:
Brandcard_brand value
Visa"visa"
Mastercard"mastercard"
American Express"american_express"
Discover"discover"
JCB"jcb"
Diners Club"diners_club"
Maestro"maestro"
UnionPay"unionpay"
RuPay"rupay"
Other"other"

​
Using credit cards in workflows

Credit cards work with Browser Task and Browser Action blocks that interact with checkout pages. The AI automatically recognizes standard checkout forms and fills card number, name, expiration, and CVV fields with the stored details. No field mapping is required. For workflows that need different cards at runtime, add a Credential parameter (type: credential_id) in the workflow editor. When someone runs the workflow, they select which card to use from a dropdown.

​
Listing credentials

Retrieve all credentials for your organization: 
credentials = await skyvern.list_credentials()

for cred in credentials:
    if cred.credential_type == "credit_card":
        print(f"{cred.name} - {cred.credential.brand} ****{cred.credential.last_four}")

​
Updating credit cards

To update a credit card’s data, use the update endpoint: 
updated = await skyvern.update_credential(
    credential_id="cred_1234567890",
    name="Corporate Visa",
    credential_type="credit_card",
    credential={
        "card_holder_name": "Jane Doe",
        "card_number": "4111111111111111",
        "card_brand": "visa",
        "card_exp_month": "01",
        "card_exp_year": "2027",
        "card_cvv": "456"
    }
)
For security, saved card details are never retrieved, so you must re-enter all fields when updating.

​
Deleting credit cards

Delete a credential permanently: 
await skyvern.delete_credential(credential_id="cred_1234567890")
Deletion is permanent and cannot be undone.

​
External provider notes

If you use 1Password as a credential provider, credit cards require a custom text field named “Expire Date”, “Expiry Date”, or “Expiration Date” in MM/YYYY or MM/YY format. 1Password does not expose the native expiration field through its API, so Skyvern reads this custom text field instead. See Custom Providers for full setup details.
