Support for HMAC authentication
Configuration Hub now supports creating HMAC-based authentication, which is a hashing-based message authentication code. The authentication mechanism helps verify whether a message or snippet of data comes from a trusted source and is not tampered with. For more information, see HMAC-based authentication.

November 2024

As part of the continued improvements to B2Bi SaaS Hub, support for the following features have been either introduced or improved:
  • HTTPS inbound and outbound connections that are either new or migrated. However, HTTP connections are not supported.
  • For inbound connections, authentication mechanism that is based on client ID and secret. For inbound connections, basic authentication is not supported. And, for backward compatibility, only basic authentication is supported for migrated connections.

    The use of 443 port is now recommended for outbound. Any exceptions to this must be done in coordination with IBM.

    You can create and edit HTTPS connections and corresponding SSL certificates. Previously, you needed to create service requests.

  • Supported authentication mechanisms for outbound:
    • OAuth2
    • Bearer token
    • API keys
    • Basic (not recommended)
    • mTLS

    You can set up to 10 custom headers and parameterized header-value mapping.

    VPN is not support for outbound connections. But you can configure a list of exceptions for allowance.

  • For cloud HTTPS adapter, you can now initiate a new flow for outbound response. This feature is not applicable in the legacy adapter.
  • Support for end-to-end visibility in InFlight.
  • Support for restart by using API or the user interface (UI).
  • Support for the GET, PATCH, POST, and PUT, methods for outbound HTTPS connections. The legacy adapter only supported the POST method. However, schedule based PULL cases are not supported. Additionally, coordinate with IBM if your file size exceeds 1 GB.
