We have a problem with APIs and even with a develop support ticket we got an answer.
Problem: APIs first need an authorization code. Once obtained, we can request tokens to be used for API access.
The token lasts 24 hours and can be regenerated as long as the last token is used and the associated refresh token is always sent.
We need to operate on our account and not on that of other people on the platform. We cannot enter a chrome job to hope to always keep this token alive.
The question: is it possible to trade using a non-expiring token? Or, using the Xmlrpc API you can operate without a token that has the prior authorization of your own account … maybe authorizing it only once and not every 24 hours. Otherwise everything becomes unusable by ecommerce obviously.
