Email management APIs

ZeptoMail's REST APIs allow users to send transactional emails like OTPs, password reset emails, invoices and more from their application. They can either use a preset template or build emails from scratch. There is a separate API that handles email-sending using templates. You can learn everything about building email templates in this guide. 

Application developers using APIs should authenticate the API requests to ZeptoMail by adding an authorization parameter. This is the Send Mail Token (a unique token for every Agent) that you can generate in your ZeptoMail account. If API requests are made to ZeptoMail without these headers, you will receive HTTP response "401 Unauthorised" error.

  1. Select the Agent that you want to connect to your application.
