API limit daily and seconds

Hi,

I’m developing system to import contacts and notes through Hubspot API.

this system work once per 1hour in a day.

Our plan Professional

Is API limit 150/10seconds. and daily 500,000.

What cause will reach API limit ?
How many call API , it’ll reach API limit ?

Ex.

03/04/2022

8:00am

I call API 150. It takes 10seconds.

9:00am

I call API 150. It takes 11seconds.

→Is this reach API limit ?

I read this

There may be a language barrier here.

If you make 150 HTTP requests to the HubSpot API, then your 151st HTTP request will not go through if it is within 10 seconds. You are limited to 500,000 HTTP requests every day.

I have not hit this rate limit at all as most of my HTTP requests are using the HubSpot Batch API.

I hope that helps.

Thank you reply to me

anyway, I should avoid 150 HTTP requests within 10 seconds.

and 500,000 HTTP requests every day.
