List consented connections for structured reads
Requires financial_data:read and CONNECT_STRUCTURED_READS. Provider capability metadata does not check current bank health or configured runtime tools.
Authorizations
A Connect app key (pgc_app_…), identifying the registered third-party app. Always presented together with connectGrant — the pair is one credential, and either half alone is refused. Accepted on the /connect/* surface only.
A Connect grant token (pgc_grant_…): one user's consent for the presenting app to reach one deployment. Every failure mode — missing, malformed, revoked, expired, or paired with the wrong app key — answers the same 401 invalid_connect_credentials.
Response
Connection IDs, labels, providers, status, and native sync support.
The response is of type object.
