Kindly refer the below link:

Multi Datasource Workspace

  1. Embedding
When embedding the dashboard for a client:
  • Generate a guest token via DataBrain’s API.
  • Pass the client’s unique ID in the token payload.
  • DataBrain will automatically scope all metric queries based on the passed Client ID.
To obtain a guest token from DataBrain, utilize our REST API from your backend system.

Cloud version:

Post: <https://api.usedatabrain.com/api/v1/guest-token/create>

Self-hosted version:

Post: <SELF_HOSTED_URL>/api/v1/guest-token/create

Simple Request Body:

{
  "clientId": "id", // "None" if no tenancy available
  "workspaceName": "workspacename",
  "datasourceName": "data source name"
}
This ensures that the same dashboard shows different, correct data for each client — securely and efficiently.
