CPQ API
Does the CPQ Quote Calculator API exist in Revenue Cloud?
No. SBQQ.QuoteCalculator (and SBQQ.QuoteAPI) are managed-package entry points for triggering a CPQ calculation from Apex. Revenue Cloud prices through the Pricing Procedure engine and offers no drop-in equivalent for programmatic calls.
How it fails
This one does fail loudly once the package is gone — which, compared with the rest of this list, is the better outcome.
What to do instead
Re-express the pricing intent as a Pricing Procedure. Expect this to be rewritten, not ported.
