API index guide
API or Application Programming Interface acts as a connection between applications or softwares, by allowing them to adopt specific functionalities (navigation, emails, payment etc.) within their application. One such functionality that application owners can adopt is transactional email-sending and related actions. This page lists all the APIs available in ZeptoMail.
The total email size which includes your email headers, body content, inline images, and attachments should NOT exceed 15 MB.
