New default install path: `C:\Program Files\Flaik\Flaik POS Integration API\`. * The install wizard now asks for your POS software type and a site identifier, and writes them into the configuration for you. * No .NET runtime prerequisite — the service is fully self-contained. * From 2.6.0 onward, your configuration files survive upgrades and uninstalls: future updates are in-place with no re-entry of connection strings or keys. * SQL migration scripts are installed to the `SQL` subfolder of the install directory, organised per POS provider. ### Performance * Improved response times for the Employee Upsert endpoint. Resort configuration data is now cached locally, significantly reducing the number of calls made to the POS database on each request. Configuration refreshes automatically every 24 hours. ### Diagnostics * Error reports now include the resort installation identifier and POS provider, making it faster for flaik to trace issues to a specific site. * The health check (`/health`) now reports the installed POS application version inside the provider configuration section. ### RTP One — Sale modifiers * Sale responses from RTP One now include prompt answers (e.g. ability level, discipline) inside the `saleModifiers` array. Each prompt entry identifies the question (`PromptName` attribute) and the answer (`itemCode`). Applies to date-range, product, and order sale endpoints. ### RTP One — Private sale changes endpoint * New endpoint `GET /api/ResortSale/privateSaleChanges?sinceDate=yyyy-MM-dd` returns the list of Order IDs and Transaction IDs for private lesson sales that have changed since a specified date. Enables efficient incremental syncing without polling the full sale history. ### Fixes * Corrected instructor-schedule batch polling so lookups for a specific batch return that batch rather than the top-priority unprocessed one. ### Database * flaik database version updated to 2.6.0.0 (run the bundled SQL scripts as part of the upgrade). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://knowledgebase.flaik.com/flaik-knowledge-base/for-it-specialists/1.-resort-pos-integration/resort-services/release-notes/version-2.6.0.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
