# Load Design ### Loading a new design Create a `spectrumLoadProduct` Javascript variable string on the window. We recommend placing this within the `` tag. ```markup ``` ### Loading a saved design Append a [recipe set](/integration/general/glossary.md#recipe) [readable id](/integration/general/glossary.md#readable-id) query string parameter to the URL of the Custom PDP. For example: ``` https://[ecommerce-website]/[custom-pdp]?recipeId=WYWYMS9L ``` Spectrum will use the `recipeId` parameter instead of `spectrumLoadProduct` if both are defined at the same time. At least one is required to load Spectrum. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
