Connection Parameter Values

Returns completion values for parameter fields on a persisted connection.

Use this endpoint when the available options for one parameter depend on the connection’s saved credentials or previously selected settings. For example, after a connection is authorized, the upstream service may be able to return lists of databases, schemas, or similar selectable values.

For new setup flows, prefer POST /api/connection_types/{type}/parameter_values, which lets you resolve completions before the connection has been created.
