Reminder: New Rate Limits for the Existing Form Submission Endpoints will be introduced on July 13th 2021

New Rate Limits for the Existing Form Submission Endpoints will be introduced on July 13th 202.

This is a reminder for our developer community that to improve HubSpot’s platform security and performance we are introducing new rate limits for the existing Forms API submission endpoints (v2 & v3) on July 13th 2021. The new rate limit will be 50 requests per 10 seconds and you can read the full details of the announcement here.

A recap on what this means for developers:

1. If your application is currently using the unauthenticated (v2 &v3)Form Submission endpoints and it requires more than the proposed 50 requests per 10 seconds rate limit, we recommend migrating to the new authenticated submission endpoints which have a higher rate limit.

  • Free/Starter accounts: 100requests/10seconds
  • Professional/Enterprise accounts: 150requests/10seconds
  • Accounts with the API Add On: 200requests/10seconds
2. If your application is using the Form Submission endpoints to record events like user logins on a SaaS product or regularly sync large amounts of data, both of which are not the intended use cases for the Forms Submission endpoint, we recommend migrating to the following endpoints instead:


Use Case Recommendation
Regular data syncing

CRM Imports API

Doc: CRM API | Imports

Or 

CRM Batch Update API

Doc: CRM API | Contacts
Recording events (like logins)

Tracking Code API

Or

Knowledge Base Article : Create custom events. Note: This is a Marketing Hub Enterprise only feature.
