refreshToken
Attempt to refresh the Token associated with this Credential.
Uses a shared orchestrator for deduplication — concurrent calls for the same credential will coalesce into a single network request.
See also
for an overload that accepts additional request parameters.
Attempt to refresh the Token associated with this Credential, forwarding additional form body parameters to the token endpoint.
When extraRequestParameters is empty, delegates to refreshToken (uses the orchestrator). When non-empty, calls the token endpoint directly — bypassing the coalescing orchestrator.
Reserved keys (grant_type, client_id, refresh_token) are silently filtered out.
Parameters
extraRequestParameters
additional form parameters to forward to the token endpoint.
