“Simpler" 3DS Integration

Drastically reduce the time it takes to integrate 3DS for customer-initiated transactions (CIT.) Our new guide walks through how to redirect a user to a URL that will fully handle 3DS coordination. Meaning, the customer is redirected to the Basis Theory 3DS authentication page to complete any authentication or challenge process. 

Implementing 3DS for CIT.

Merchants that perform transactions without the customer present at checkout would need 3DS MIT (Merchant Initiated Transactions.) 

Documents

The Documents API is a secure file management service that allows you to upload documents and store them securely—but retrieve them when needed. 

Regulated industries that need driver's license numbers, passports, tax documentation, or social security cards don't need regular access to this data. For Vertical SaaS platforms, keeping information separate from each processing partner allows for a cleaner onboarding of any new processing partner.

Read the Documents API documentation. 

Platform Speed Improvements

Because of network optimization changes within our internal architecture, the majority of API calls are 30% faster. These performance increases are across the board.

Here are some performance numbers the team has gathered for Web Elements:

• First Time Load: 230 → 120ms.
• After Cached: 110ms → 80ms.

These changes are live and available in Elements v1.20.0 🎉
