Does API key and OAuth share different limit?

[JZhao]

I am reading HS API limit: https://legacydocs.hubspot.com/docs/faq/working-within-the-hubspot-api-rate-limits

I have one application use API key for authentication and another application use OAuth authentication. Do they share the same API limit? Or does API limit work separate for them?

Hi @JZhao ,

The API limits for OAuth apply per app per portal. So one install of your app has the 100/10 burst limit. The second install in a different portal will have a new burst limit of 100/10.
So the limits apply per install and not per token.

Hi @JZhao ,

You can check the API limits here. To answer your question, they have different limits. oAuth has a burst limit of 100 requests per 10 seconds and no daily limit. API keys have a different burst limit per Hub and a daily limit.

OAuth:

• No daily limit
• Burst limit of 100 requests per 10 seconds (100/10 seconds)

API Key (different per hub):

• Free and Starter: 100/10 seconds burst limit, 250.000 daily limit
• Professional and Enterprise: 150/10 seconds burst limit, 500,000 daily limit
• API Add-on (any tier): 200/10 seconds burst limit, 1,000,000 daily limit

If there are multiple valid oauth tokens, are each of them have separate api limit? or are they share the same API limit?
