Hey @ALaskey
Based on the limit you are running in to, it sounds like you may be using a development store. This is noted in our REST documentation here
Usage notes:
If you’re using this endpoint with a trial or Partner development store, then you can create no more than 5 new orders per minute.
For bulk operations, only the mutations currently listed in the document you shared are compatible.
The best option here is to plan for the order migration once the shop is on a live plan so that the standard API rates will apply and it won’t be throttled.
Good call out on the docs, I’ll pass some feedback on to our docs team as that would be useful to note in our Graphql docs as well.
