Required Scope

transactional-email

This endpoint is used to create an SMTP API Token. An API token provides both a username and password which can then be used to send email through the HubSpot SMTP API:

  • SMTP Hostname: smtp.hubapi.com
  • SMTP Port: 587 (for STARTTLS) or 465 (for TLS)
  • SMTP User Name: provided in the userName field
  • SMTP Password: provided in the password field

Once an SMTP API Token is created, it can be used to send emails and track events throughout the HubSpot product. Here are a few ways to use a token once created:

  • In the Email Campaign Data API you can use the emailCampaignId and appId fields
  • In the Email Event API you can get specific details about events that occurred for the email.
  • In Contacts dynamic list definitions, under "Email Event" you can search for a campaign name to dynamically update a contacts list based on events sent with the token.

Note that use of API requires the Transactional Email add-on.
