Hi,
I need to know if the public app that I create will follow the rate limit for my account or is it based on each user connecting to my app?
From documentation its mentioned for private app.
Is there any specfic details for public app
Hey @Abishek-d 
Here’s what the documentation states —
“Apps using OAuth
For OAuth apps, each HubSpot account that installs your app is limited to 100 requests every 10 seconds. This excludes the Search API, as noted in the Other Limits section below. Limits related to the API Add-on don’t apply.”
I hope this helps get you moving forward! — Jaycee
Hello @Abishek-d
If you are using Oauth in your public aplication using the API, there is a 100 request limit for every 10 seconds. If youre wondering it, you can do 99 request in a second if you need to, just be carefull to not do more calls in the few next seconds.
BUT if you use the SEARCH API the limit is defined at 4 request per second.
You can find all this information here.
Please mark the answer as a solution if you found it useful.
Regards.
