Hellgate Web SDK (v3.11.0)

Central Control Over Card Saving

Decide once, when you create a session, whether cards are saved — always, never, or left to the cardholder — and the SDK enforces that policy at checkout. Your card-retention rules stay consistent across every page that embeds the SDK, with nothing extra to implement in each frontend. The SDK also tells you which policy is active, so you can show a “Save my card” checkbox only when the cardholder really has the choice.

Improvements and bugfixes

  • A cardholder’s decision not to save their card is now always honored. Previously, in some integrations, declining to save a card could still result in a saved card.
New Release
Link — the protocol-abstraction runtime of the Composable Payment Architecture — now has public documentation. Link is the platform’s PSP and provider connectivity layer: define a versioned API contract (a protocol) once and bind it to any provider through declarative backends, so integration becomes configuration, not code. It is the component Commerce routes through to reach acquirers and PSPs, and that Specter reaches through to call external risk engines.Explore the overview, core concepts, and the API reference.

Hellgate Web SDK (v3.10.0)

Cardholder-Aware Token Lifecycles

Align token retention with what your cardholder actually agreed to. A new optional ephemeral?: boolean argument on process() and tokenize() defaults to true, meaning the cardholder is not remembered. Flip it to false only on explicit consent — for example, when a customer ticks a “Save my card” box at checkout.

Smarter Scheme Validation

Allowed card schemes configured on the session now flow through to client-side card number validation. Cardholders see scheme errors immediately, before the request ever leaves the browser.

Improvements and bugfixes

  • Empty card_schemes configuration now correctly allows all schemes.
  • Separate expiry month/year inputs now treat '1' as a valid month and properly reject past-expiry dates.
  • Demo: a new “Save my card” checkbox in the tokenization demo wires straight into the new ephemeral toggle so you can try it end-to-end.

New ReleaseImprovement

Hellgate Android SDK (v1.1.0)

The Android SDK now encrypts the full payload — including any additional data — into a single JWE and returns it to your app, instead of calling the tokenization backend directly. This simplifies your integration and keeps sensitive data encrypted end to end.

Improvements and bugfixes

  • Additional cardholder data is now encrypted as part of the JWE token.
  • Hellgate error responses now surface with clearer, more actionable detail.
  • Removed support for tokenizing through an external token provider.
  • Updated environment URLs.
Improvement

Hellgate Web SDK (v3.7.0)

Add ‘onSessionComplete’ handler to Hellgate® client with result data.
Improvement

Hellgate Web SDK (v3.5.3)

Improved the SDK with small but important fixes:
  • Fix masked input behaviour
  • Reject cardHandler.process() promise if BE responds 40x / 50x status code
  • Await cardHandler.process() throws exceptions if card date is not complete or invalid
  • Show full CVC code up to 4 digits
  • Card scheme validation by default
  • UnionPay card number input
Added some new features:
  • Encrypt additional_data payload on tokenize
  • User can refresh CVC2 code of a token from WebSDK
New Release

Hellgate iOS SDK (v1.0.0)

The first release of the Hellgate® iOS SDK brings cardholder data tokenization to native iOS apps. Collect and tokenize the card number, CVC, and expiration date, and attach additional fields to capture cardholder information — so raw card data never touches your own backend.
New Release

Hellgate Android SDK (v1.0.0)

The first release of the Hellgate® Android SDK brings cardholder data tokenization to native Android apps.
