I have tried to ask the following question via chat, but I was recommended to ask in the developer forums.
In the following page: https://www.hubspot.com/pricing/service-limits
we find that the limit is 40,000 API calls per day (without the API Add-on)
We are in a situation where one customer will exceed these limits and we want to know what the price is for an API Addon to be able to update up to the limit of 160.000 contacts per day. It might be necessary if we are not able to export the last changed contacts for the last x hours. (We could of course store the data in a temp-database - but…)
Who can give us an answer on this issue?
I have also found some info here, but no pricing info regarding the different addons.
