Outlook OTP inbox API
Arrange Outlook.com inbox access for incoming verification email and retrieve OTP messages through an API-based business workflow, subject to service-specific availability.
Incoming Outlook verification email
The target service sends its verification message to the arranged Outlook.com inbox. Your authorized application then retrieves the incoming OTP through the agreed API workflow.
This service does not send OTP emails and does not make Microsoft validate a code. The issuing service remains responsible for verification.
Test the sender and domain together
Start with the exact service you plan to use. Confirm that the expected email reaches the Outlook inbox and that your workflow identifies the current message rather than an older code.
Once the test is satisfactory, regular volume and API access can be discussed.
Outlook, Hotmail and Gmail options
Hotmail.com and Gmail.com inbox options can also be requested for supported workflows. Outlook and Hotmail are Microsoft services; Gmail is operated by Google.
SMS Activation API is independent of Microsoft and Google. Access must only be used for accounts and workflows you are authorized to manage.
Add SIM verification where required
If the same workflow also needs phone verification, ask about virtual or physical SIM numbers across 189 countries. Phone and email availability are confirmed separately by route.
