In some of the other API endpoints you offer, there are limitations for the number of entities you can send per request (for example updating a group of tickets is limited to 100 entities per request, updating a group of contacts is limited to 1000).
The Sync Messages API doesn't specify a limit to the number of messages you can send per request. Are there any limitations to this? Or are there any suggested limitations to keep performance optimal?
For example, I need to send a few thousand sync messages. Should I send them all in one go? Should I batch them in multiple requests?
