What’s happening
API calls authenticated using OAuth 2.0 will now return X-HubSpot-RateLimit-* headers. Previously this was restricted to API calls authenticated with an API key. OAuth authenticated calls will not include X-HubSpot-RateLimit-Daily or X-HubSpot-RateLimit-Daily-Remaining because there is no daily limit for these calls. This does not impact the enforcement of any rate limiting.
Adding these headers will make it easier for you to understand and manage the pace of API calls you are making to HubSpot. For more information on working with rate limiting in general, take a look at our documentation.
This change is now live for all apps and accounts.
