Your Discount Code Mapping BSD sheet allows you to specify which discount codes should be associated with which channels and vendors. Using these dimensions, you won't need to use complicated "discount code contains xyz" filters every time you want to analyze how much revenue a particular offline campaign generated. Instead, you just specify the rules once in your BSD sheet and then use the Discount Code Channel and Vendor dimensions during your analyses. --- # 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://help.daasity.com/advanced/marketing-attribution/discount-code-attribution.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.
