To obtain a guest token from DataBrain, utilize our REST API from your backend system. Each request will generate a unique guest token, ensuring security and flexibility. Once you acquire the guest token, you can seamlessly pass it to your frontend application, where it can be integrated with the web component.
Create API key from Databrain's dashboard that should be passed in the headers in these requests.

​
Quick start (simple use case):

When you need a guest token that you want to use across dashboards and metrics, all you have to do is pass clientId, dataAppName. If expiryTime is not passed, the token will not expire.

​
Cloud Databrain:

POST https://api.usedatabrain.com/api/v2/guest-token/create

​
Self-hosted Databrain:

A metric level filter designed specifically for controlling access to individual metrics. Unlike general RLS settings, it restricts access without requiring end user input or control. 
{
  "clientId": "id", //"None" if no tenancy available
  "dataAppName": "dataappname",
  "params": {
    "appFilters": [{
      "metricId": "The id of the metric you want to have app filters",
      "values": {
        "paid_orders": true,
        "amount": 500,
        "country": ["USA", "CANADA"] || "USA", // based on filter variant (select or multi)
        {
          "sql": "SELECT \"name\" FROM \"public\".\"countries\" WHERE isEnabled=true",

Dashboard App Filters:

​
Request Body with Dashboard filters:

{
  "clientId": "id", //"None" if no tenancy available
  "dataAppName": "dataappname",
  "params": {
    "dashboardAppFilters": [
      {
        "dashboardId": "dashboard-id",
        "values": {
          // single string
          "name": "Eric",

          // multi select
          "country": ["USA", "CANADA"] || "USA", // based on filter variant (select or multi)
          {
            "sql": "SELECT \"name\" FROM \"public\".\"countries\" WHERE isEnabled=true",
            "columnName": "name"
          },

          // date-picker
          "timePeriod": { "startDate": "2024-01-01", "endDate": "2024-3-23" },

          // range
          "price": { "min": 1000, "max": 5000 }
        },
        "isShowOnUrl": true // true/false
      }
    ]
  }
}
In the above code snippet, "name", "country", "timePeriod", and "price" are Dashboard App filters.
When you disable the isShowOnUrl, the filter will not be visible to end users as search params on URL.

  "clientId": "id", //"None" if no tenancy available
  "dataAppName": "dataappname",
  "datasourceName": "data source name"
}

{
  "clientId": "id", //"None" if no tenancy available
  "dataAppName": "dataappname",
  "params": {

  }
}
