Is there an api I can use to setup initial configuration (create an organization, create an admin user)

Based on the provided knowledge sources, there isn't a specific API endpoint mentioned for setting up the initial configuration such as creating an organization or an admin user in Airbyte. However, there is a mention of a

/v1/instance_configuration/setup

API in a [Github issue](https://github.com/airbytehq/airbyte/issues/10834) which supports configuring

initialSetupComplete

. For more detailed information, you may want to refer to the [Airbyte API documentation](https://airbyte-public-api-docs.s3.us-east-2.amazonaws.com/rapidoc-api-docs.html).
