Restrict the Transactional Email SMTP endpoints to OAuth authentication only and sunset API key usage
Announced: February 19, 2020
The usage of API keys for the Transactional Email SMTP endpoints listed below is being sunset.
We’re ending API key usage for these 3 endpoints starting today unless your account has accessed these endpoints in the past 6 months.
We’ll be contacting all HubSpot accounts that have used API keys to access these particular endpoints only in the last 6 months with more details and a plan for updating their integrations.
This is being done to increase the security, privacy and protection of our email sending platform. Customers must use OAuth to authenticate using these endpoints moving forward.
When is this happening?
