/data-sources needs datasources:read to view and datasources:write to change. The engineer guide has the screenshots: Data Sources.
The page
Four cards (Total Sources, connected, Issues, Cost Today), status tabs (All, Connected, Degraded, Error) and the Integration Status table with Provider, Status, Response Time, Requests, Cost/Req, Success Rate, Enabled and Actions.Adding a provider
Add Source opens Add Data Provider: choose a provider from the catalog, optionally turn on Use own credentials and fill the provider’s credential fields, then Add Provider.Provider settings
The gear opens the provider’s settings: enable or disable, update credentials, read metrics, or Remove data source.Per-dataset configuration
Which dataset a flow calls and with which inputs is configured on the Integration node in the workflow builder, not on this page. See Nodes: Integration.Test in the row actions reports the cached status rather than probing the provider, and Success Rate and Cost/Req are placeholder values until provider telemetry lands. There is no priority ordering between providers and no custom-provider form; the catalog is fixed.
