In my node I use an API with OAuth authentication.
I save the refresh token in the node credentials.
When the access token is refreshed, the API also returns a new refresh token.
How can I save the new refresh token in the credentials file at runtime?
I already tried it with RED.nodes.addCredentials (node.id, credentials);, but this does not change the credentials file.
After a restart, the old refresh token is active again.

Hi @alexkn
There is a long standing issue on the backlog to help handle this scenario.
Currently the only way to save anything to the credentials store is via a deploy - not something nodes are allowed to trigger of their own accord.
Until someone figures out how best to handle this scenario your options are limited.
