SDK Localization

The Knot SDK now supports localization, allowing you to present the merchant linking experience in your users’ preferred language.

Localization is available across all SDK platforms — iOS, Android, React Native, Flutter, and Web.

New Subscription Merchant Integrations

SubscriptionManager now supports retrieving subscription data across additional merchant coverage (outlined below). Subscription details for these merchants can be retrieved via the Get Subscription By ID endpoint.

  • Bills: Xfinity Mobile & Internet, T-Mobile, Metro by T-Mobile, Verizon, Boost Mobile, Spectrum, Straight Talk

Detect API

You can now programmatically access detected merchant accounts via two new endpoints. Sync Detected Accounts retrieves all detected accounts for a user, while Search Detected Accounts lets you search by merchant or company name to check if a user has an account at specific merchants. The NEW_DETECTED_ACCOUNTS_AVAILABLE webhook notifies you when new accounts have been detected. Use this to personalize the reward offers you present in your app to users or re-engagement lifecycle marketing campaigns based on which merchants your users have accounts with.TransactionLink now supports Shop Pay as a merchant integration. Because Shop Pay is used across millions of Shopify-powered merchants, this single integration unlocks SKU-level transaction data for a significantly expanded merchant footprint. Transaction data is available via the Sync Transactions and Get Transaction By ID endpoints.

Session Metadata in Webhooks

You can now attach custom metadata (arbitrary key/value pairs) to SDK sessions via the Create Session endpoint, which will be included in your webhook payloads. This is useful for passing reference tokens, internal correlation IDs, or any data you’d like echoed back without maintaining a separate mapping.

Seller Data in Transactions

Transactions now include a seller object on products, identifying whether an item was sold by the marketplace or a third-party seller — helpful for distinguishing first-party vs third-party purchases in your transaction analysis. Seller data is available on the Sync Transactions and Get Transaction By ID endpoints.

Detected Merchant Accounts in Dashboard

A new Detected Accounts page is now available in the Knot Dashboard, showing which merchant accounts have been detected for your users via Detect. This makes it easy to monitor detection coverage and verify that accounts are being surfaced correctly.

CardUpdater on Card Endpoints

The Switch Card and Switch Card (JWE) endpoints now support CardUpdater flows. This allows you to initiate a card update by passing external_user_id and merchant_id directly, without requiring an active SDK session.

Products Page in Dashboard

A new Products page is now available in the Knot Dashboard, providing an overview of all Knot products — CardSwitcher, Detect, TransactionLink, CardUpdater, Shopping, and Vaulting — with descriptions and quick-start links to help you get up and running faster.

Domain Allowlisting Now Optional

Web SDK integrations no longer require domain allowlisting by default, removing a common friction point during integration setup. If you’d like the additional security of domain restrictions, you can still enable it in your Knot Dashboard settings.
