As a dashboard designer or administrator, you may want to retrieve a thumbnail image from a dashboard, to display on your webapp, in an email or any other medium.
Example of a potential app, where tumbnails are displayed above the dashboard names and the "last updated" times.
If you have a public dashboard in Luzmo, you can access its thumbnail image by simply adding its ID to the following URL. For example, if your dashboard ID is "123456" and your desired size is 256 pixels (512px is also permitted), your thumbnail image URL would be:
https://app.luzmo.com/thumbnail/securable/256px/123456.png
If you have a private dashboard in Luzmo, you need to request an embed token to access its thumbnail image. This is needed because thumbnails are snapshots of the dashboards and may contain sensitive information. Please follow the guidelines provided in our Developer Documentation or the specific Academy article on generating Embed Tokens.
Once obtained, this token can be used to securely access your dashboard's thumbnail.
For example, if your dashboard ID is "123456", your desired size is 256 pixels (512px is also permitted), your temporary key is "abcd1234" and your temporary token is "efgh5678", your thumbnail image URL would be:
https://app.luzmo.com/thumbnail/securable/256px/123456.png?key=abcd1234&token=efgh5678
It's important to keep in mind that the data in thumbnails may be confidential. The thumbnails are generated when a dashboard is created/edited and will contain the data as accessible by the dashboard designer. This means that if your dashboard contains sensitive information, such as personal or financial data, it may be exposed through its thumbnail image.
As a potential alternative, please consider exporting the dashboard via Luzmo's API, using an Embed Token. This allows for the application of filters, parameter overrides, and connection overrides, ensuring only the intended data is displayed and shared.
