Additional context: we batch push contacts to sync in HubSpot but we're consistently hitting the secondly limit without reaching any daily limits from HubSpot. Just want to clarify, do batch API calls count as 1 API call or multiple API calls?
Happy to clarify. A batch API call (e.g. Create or update a group of contacts) only counts as one call.
Each batch API has its limits, however. If you're updating 700 companies at once, for example, that would take at least 7 API calls. Combined with other calls in the same second, you could easily hit the 10 call-per-second limit.
