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

1

Open the Add dialog

Click + Add → Credit Card from the Credentials page.
2

Fill in the card details

Provide all required fields:
FieldDescription
NameA label like “Corporate Visa” to identify it later
Cardholder NameName printed on the card
NumberFull card number (spaces added automatically as you type)
BrandCard network: Visa, Mastercard, American Express, Discover, JCB, Diners Club, Maestro, UnionPay, RuPay, or Other
ExpirationMonth and year in MM/YY format (slash inserted automatically)
CVV3 or 4 digit security code
3

Save

Click Save. After saving, the card number is masked and only the last four digits are ever shown again.
Add Credit Card credential modal Saved credit card credential showing masked card number

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. This lets the same checkout workflow work with different payment methods.
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 External Providers for full setup details.

Editing and deleting

To edit a credential, click the pencil icon on its row. For security, saved card details are never retrieved, so you must re-enter all fields when updating.
Click the trash icon on any credential row to delete it. Deletion is permanent and cannot be undone.
