We have our ordering tool synced with Hubspot via API calls.
We hit every second day the limit of 10 api calls per second (eg. when 2 customers order at the same moment)
We don't have a throttle system in place as it will just postpone the problem in our opinion (eg. if we retry 2 seconds later, and this is going on over days. We might end up with a deal being updated 1 day after it was actually closed in our ordering tool or every deals being postponed couple of seconds depending on how we set it up).
Do you have any recommendation?
