Moving from MWS habits to SP-API thinking
The endpoints changed, but the habits that need changing are older than that. Several things that worked fine under MWS are now the reason your integration is slow.
Concrete, practical guides - written by people running the same operation. No fluff, no "10 best tools" listicles.

The endpoints changed, but the habits that need changing are older than that. Several things that worked fine under MWS are now the reason your integration is slow.
Three separate problems roll into one number, and at low volume a single incident can put you over the threshold. Knowing which components move it matters.
A refunded order has two sides and they do not settle together. The gap between them is where dropshipping money quietly disappears.
The settlement report is the only honest record of what you earned. It is also formatted for accountants rather than sellers, which is why most people never read it.
The orders endpoint gives you less than sellers expect, and the missing pieces live in three other calls. Knowing which is which saves a rewrite later.
VTR is not about whether you uploaded a number. It is about whether that number scanned with a carrier Amazon recognises - which is a much harder test.
Every integration eventually breaks at 3am because a token expired and nothing renewed it. The lifetimes differ, and so does what happens when you get it wrong.
The right answer depends less on audience size than on whether your current operation can absorb another set of deadlines, metrics and dispute rules.
What you are allowed to say, where you must say it, and how fast. Habits from one platform will get you a policy warning on another.
Two of them hand you an absolute deadline and two make you derive it. That difference changes how you plan a working day across channels.
eBay derives your dispatch deadline from a handling time you set. Getting that setting wrong is the most common self-inflicted metric problem on the platform.
A case does not appear out of nowhere. There is a sequence with defined windows, and knowing where the intervention points are changes the outcome.
