Sender APIs is the place where you can make use of an authentication mechanism to connect Zoho Campaigns Email API with your application and send emails using our APIs. We provide both REST API and SMTP API as methods of integration. Zoho Campaigns Email API uses the API Key mechanism for authentication and authorization.
API Key
Email API uses the API Key-based mechanism for authentication and authorization.
API
keys provide a simple and secure way to authenticate API requests. Each
API key is uniquely associated with your account and must be included
in your API requests to authorize access.
API key authentication:
1. Eliminates complex token flows
2. Does not require user consent redirects
3. Is easy to generate and manage
4. Provides controlled access to your resources
Keep your API key confidential and avoid exposing it in client-side code or public repositories.
The steps for the setup process would be present in the section.
SMTP
SMTP stands for Simple Mail Transfer Protocol. It is a protocol used in sending and receiving emails across the internet. It serves as the backbone of email communication, ensuring your messages reach their intended recipients efficiently and securely.
You can integrate Zoho CampaignEmail API with your SMTP server to perform email delivery tasks. The main advantage of using SMTP integration is that it allows you to send emails from your own email clients or any SMTP sender to our SMTP server using the standard SMTP protocol, instead of using Zoho's REST API. There is no separate authentication mechanism for SMTP. The same API key generated for your account can be used.
The Server Name, Port Number & Authentication details will be present in the SMTP tab. You can make use of those details to perform the integration at your SMTP server.
