Talon.One MCP server improvementsInfrastructure​

The Talon.One MCP server now supports OAuth 2.0 and role-based access.

When connecting your Talon.One environment to AI agents, you can now sign in with your Talon.One account instead of using a shared API key. Once connected, AI agents automatically inherit and follow your role permissions.

New endpoint for structured rulesetsManagement APIBeta​

The new Create ruleset (V2) endpoint lets you create a ruleset in structured, human-readable format as a JSON object. New JSON objects will be added in future releases.

More updates
Enhancements:
  • Achievements: In the attribute selector of the Rule Builder, you can now search for attributes by achievement ID.
  • Experiments: Updated terminology for experiments in the Campaign Manager.
  • Integrations: The new Integration Hub status page shows the status of your instances and the events sent to them.
  • Loyalty: pointsToNextTier and nextTierName are now available as built-in attributes in the Rule Builder, custom effects, and webhook payloads. Both attributes are based on values from the Get customer's loyalty balances endpoint.
  • Notifications: Added the pageSize parameter to the List message log entries endpoint. This parameter allows you to configure the number of message log entries to return.
  • Rewards: You can now search and filter the Rewards list by name, Application, and status.
  • Strikethrough pricing: Lowered the minimum payload size of notification requests to 50 items for strikethrough pricing updates to prevent integration errors.
Bug fixes:
  • Achievements: Fixed a bug where the ID of an account-level achievement was not shown in the Conditions section of the Rule Builder.
  • Experiments:
    • Fixed an error that occurred when copying an experiment with no rules.
    • Fixed an issue where experiment analytics didn't include sessions for variants whose effects don't change the session, such as adding a customer to an audience.
