Send Basic Emails API

Backendless provides API for basic email delivery. The API lets you specify:

  • plain text and/or HTML-based content for your email messages;
  • a list of email address for the recipient;
  • a list of attachments;

Important

Before the API can be used, the Backendless backend must be configured with your own SMTP server information. This is an important requirement as the API will not work when the Manage > App Settings > Email Settings section in Backendless Console contains default values. For instructions on how to configure your own SMTP server in Backendless, see the Email Settingssection.

Sending Email API

Delivers an email message to the recipient(s) specified in the API call.

where:

Argument                Description
subject email message subject.
messageBody plain text or HTML body of the email message.
bodyParts an instance of com.backendless.messaging.BodyParts class which contains either plain text and/or HTML version of the message body.
recipient email address to deliver the email message to.
recipients a collection of email addressed to deliver the email message to.
attachments an array of file paths for the file entries from the Backendless File Service. Referenced files will be attached to the email message. The path is calculated from the root of the file system (as it is seen in File Service browser in Backendless console) without the leading slash. For example, if file agreement.txt is located at /documents/legal/, then the path in the API call must be "documents/legal/agreement.txt".
responder the callback used for asynchronous calls to indicate that the operation has either successfully completed or resulted in error.
