Temp Mail API for OTP Testing
The OTPMail API gives developers and QA teams a simple way to read temporary inboxes during sign-up, login, and email verification tests. It is useful when you need to confirm that an OTP email is delivered without connecting a real mailbox.
This page is for developers and QA automation. For manual OTP use, start with receive OTP online. For human-facing privacy guidance, read temporary email for verification.
What the API is for
A temp mail API is most valuable in development and testing. You can generate a disposable address, trigger the email in your application, poll the inbox, and extract the OTP or confirmation message. This helps verify that email templates, delivery, and user onboarding flows work as expected.
Basic endpoint
The public API reads the latest message for a temporary address. For full examples and current response fields, use the official API documentation.
curl https://api.otpmail.online/api/test@otpmail.onlineRecommended polling behavior
Do not poll aggressively. A 10-second interval per inbox is usually enough for OTP delivery. If you run automated tests, add a timeout, retry a limited number of times, and handle an empty inbox response cleanly. This prevents unnecessary load and keeps the service reliable for other users.
Typical use cases
- End-to-end tests for email verification.
- QA checks for OTP delivery and message formatting.
- Development environments that need disposable recipients.
- Manual support workflows where a temporary address is enough.
Important limitations
Temporary email is not a substitute for a secure user account. Do not rely on it for long-term identity, password recovery, financial services, or private data. Emails expire quickly and temporary addresses can be guessed or reused by others.
