Embedded Dashboard Prerequisites
To embed a dashboard into your own application, the following prerequisites must be met:
You must have created a host application into which you want to embed a Composer dashboard.
OAuth authentication must be enabled. It is enabled by default. See Enabling OAuth 2.0.
Cross-origin sharing (CORS) must be enabled for your Composer instance. See Enabling Embedded Dashboard Access From Other Sites Using Cross-Origin Sharing (CORS).
You will need to be a Composer administrator or a user assigned to a group with the Can Generate Embed Codeprivilege so you can generate the dashboard snippet used for embedding.
