Email API portal
One clear way to send email from your apps.
MailSendApi gives your applications a secure, consistent API for requesting access and sending email through verified sender accounts managed in this portal.
Credentials and sender access are managed per application.
Simple integration
Everything your app needs to get started
Use the portal-issued credentials to request a token, then call the universal email endpoint. The sender's profile controls delivery.
POST
Send an email
/v1.0/users/{email}/sendMail
Recommended for all senders. The portal routes through the current provider profile.
POST
Send an email
/v1/email
Existing Graph-compatible integrations can keep this URL and request format.
Getting started
From setup to first send
Manage access in one place, then integrate with a short token-and-send flow.
1
Set up a sender
An administrator creates an application sender and gives it the email addresses it is allowed to use.
2
Use your app credentials
Exchange the tenant, client ID, and client secret issued for that sender for a portal access token.
3
Make an API request
Send to the endpoint that matches your integration and review activity in the portal logs.
