To avoid potentially restrictive per user, per namespace, per hour ConnectApi rate limits, we’re migrating orgs to the per org, per 24-hour Salesforce Platform API rate limit. Orgs created in Summer ’24 and later are already using the Salesforce Platform API rate limit. For migrated and new orgs, only method calls that require Chatter are subject to the per user, per namespace, per hour rate limit.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the Salesforce mobile app in all editions in all API versions.
When: Org migrations to the Salesforce Platform API rate limit continue on a rolling basis. Migrations occur in the background without notification.
