# Create a connection

`POST /v3/connections`

Creates a connection to a data warehouse.

The `config` object depends on `provider_id` and on the authentication
method — see the examples below. Secrets you send here are stored encrypted
and never returned by any endpoint.

  - `provider_id` 'bigquery' | 'snowflake' | 'redshift' | 'postgres' | 'databricksRest' | 'databricksWarehouse' | 'oracle', required
  - `config` object, required — Provider-specific configuration. `type` selects the authentication method and `credentials` holds the secrets — see the examples.
  - `privacy` 'private' | 'shared'
  - `groupIds` string[] — Required when `privacy` is `shared`.
