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`](../../../../api-reference/connections/get-type-parameter-values),
which lets you resolve completions before the connection has been created.
