Restrict the Transactional Email SMTP endpoints to OAuth authentication only and sunset API key usage

February 19, 2020

What’s happening

The usage of API keys for the Transactional Email SMTP endpoints listed below is being sunset.

Create SMTP API Tokens

List SMTP API Tokens

SMTP API Tokens - Password Reset

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?
