Your users want to pay with their new card. Getting it on file is the hard part.

Authenticate. Operate. Extract.
Deck agents authenticate as your users, operate any platform, and extract the data you need — structured, validated, and delivered to your pipeline.
Your users connect once
End users link their platform accounts through Deck. Credentials are encrypted in Deck Vault. Sessions persist. MFA is handled automatically. Your application never touches a password.
Agents operate any portal
Computer use agents navigate real platforms — Shopify, Stripe, Salesforce, and thousands more. They authenticate, navigate pages, and complete tasks. No scrapers. No selectors.
You get structured results
Every action returns structured output and schema-validated JSON. Define the output and Deck delivers it consistently, ready for your pipeline.
One API call. Payment method updated everywhere.
Deck handles the end-to-end payment switch — accessing merchant accounts, performing the update, handling tokenization, and confirming the change — using the user’s authorized credentials.
Cross-merchant updates
Deck updates the payment method on file across every platform your user has a subscription or recurring charge — no merchant API required.
Tokenization handled
Deck manages the secure transfer of payment credentials where tokenization is required. Your team doesn’t need to build or maintain that logic.
Confirmation back to your system
Every successful update is logged and returned to your platform. Failed updates are surfaced with the reason — so you can act on them.
Works where APIs don’t exist
Most payment switch competitors require merchant API partnerships. Deck works through the browser — so the coverage is the actual web, not just whatever merchants signed a deal.
From authorization to confirmation.
User authorizes Deck
Through your product’s UX, the user grants Deck permission to update their payment method across their linked accounts.
Deck runs the switch
Agents access each merchant or platform, authenticate, and perform the update following the platform’s own UI flow.
Results returned to your system
Successful updates and failures are logged and sent back to your ingestion endpoint in real time.
