[Now Live]: New and Improved HubSpot API Limits

June 6, 2019

Edit:  This is now live. If you have any questions or comments, join the discussion on our forum post

We’re excited to share that in the coming weeks, HubSpot will be making some significant changes to our API Limits for all developers, customers, and users of HubSpot.

We understand that improving the capacity of our daily and per second API limits have been a top request for some time and we want you to know that we are listening and have been hard at work to better meet your development needs. These improvements will impact developers using OAuth and API Key (or HAPIkey) resources.

Here’s what’s changing for developers using OAuth

Today, any API calls made using OAuth are not subject to the per day call limit. However, they are subject to the 10 calls per second (or secondly limit). When the changes take effect, integrations using OAuth will have a new per second API burst limit of 100 calls per 10 seconds per app per portal, allowing your applications to have more flexibility when they need it the most.

Here’s what’s changing for developers using HubSpot API Keys

Both the daily and per second burst limits will be automatically updated to the following structure when the changes roll out. Please keep in mind that these limits apply to all HubSpot Product Hubs (Marketing, Sales and Service):


  Product Tier Old Limits New Limits

Free & Starter

Burst: 10/second
Daily: 40,000

Burst: 100/10 seconds

API Key Limits with API Add-On Any tier

Daily: 160,000

Burst: 120/10 seconds
Daily: 1,000,000


Here’s what you need to do

These changes will go into effect automatically, so there’s nothing that you need to take action on your end. For full details on all of these changes, please refer to this product blog post.

We hope these changes will better serve your business by allowing more flexible ways to bring your data into HubSpot. If you have any additional questions, please feel free to start a discussion on our forum post
