What This Section Covers
API workflows for connecting to a user’s credit cards — card discovery, brand enrichment, transaction streaming, and tokenization for checkout and card-on-file experiences.Example Use Cases
- Payment processors that tokenize linked cards for checkout and recurring billing
- E-commerce platforms that enable card-on-file and one-click pay with existing credit cards
- Loyalty and rewards apps that link cards for offer activation and transaction-based rewards
- BNPL providers that connect existing cards for repayment or split-pay flows
- Expense management tools that stream transactions and categorize spend across employee cards
How Method Enables End-to-End Commerce
Every commerce integration follows the same high-level journey: connect the user’s credit cards, enrich them with brand and transaction data, and enable action through tokenization or checkout.Two Integration Paths
- API-Only
- Embedded UI (Opal)
Integrate directly with Method’s APIs for entity creation, identity verification, Connect, and all downstream card operations. You build the user-facing flow and have full control over the UX.PCI compliance is not required: by default, tokenization returns network tokens that don’t expose raw card credentials.
