Hi @stevenb! First of all, welcome to the forum! Regarding the availability of Advanced Trading API, the team are still hard at work on building this API and there will be a lengthy grace period for Pro API users to migrate over to Advanced Trading API. Coinbase Pro APIs will not be impacted or sunsetted until a suitable replacement is available on Coinbase Advanced Trade.
We would like to reiterate the links below to know more about Coinbase Advanced Trade and a breakdown of how it compares to Coinbase Pro:
