The Transactional Injection Feed

While the feeds in the previous section: Ongage Feeds: HTML, RSS, XML and JSON use a URL to retrieve dynamic content from an external content/web server to populate outgoing email messages, with this feature you can specify the dynamic feed directly within the Transactional API call. 

Use Cases

A powerful feature for eCommerce and travel

• This is a powerful feature for eCommerce and travel sites. With it one can send transactional emails of purchase summaries (e.g., purchase line items) or reservations details (e.g., hotel, room, itinerary line items, etc.).
• The feature enables marketers to use the same email message, yet each recipient will get a tailored message, of their reservation details, or purchase summary, based on the dynamic content values in the feed.
• These API calls with their tailor feeds are generated using data retrieved from the email marketer's back-end CRM, Accounting or Reservation platform. 

Setup Required to send Transactional emails using an API Injection Feed

Email Message

Your email message will include Dynamic List Fields (aka List Fields) as well well Dynamic fields that you will populate through the Transactional API Request.

For example here is how your email message might look like this:

Please note how the email message includes "{{ocx_feed{param=dynamic_feed}}}" where the param= dynamic_feed replaces the content URL and it will be used to add XML feed is the name of the feed in the API call and contains the XML data as parameter in API request.

The XML FEED

For any particular contact, the XML feed to populate content in above email message will look like below.

<feed>
  <mailing>
    <blocks>
      <block>
        <name>blockName</name>
        <items>
          <item>
            <variables>
              <variable>
                <key>title</key>
                <value>Your Order Confirmation</value>
              </variable>
              <variable>
                <key>classSummary</key>
                <value>Here goes the summary of transaction</value>
              </variable>
              <variable>
                <key>classUrl</key>
                <value>www.domain.com/class/Destination-Link</value>
              </variable>
              <variable>
                <key>classAmount</key>
                <value>$123,123</value>
              </variable>
            </variables>
          </item>
        </items>
      </block>
    </blocks>
  </mailing>
</feed>

Transactional API Request

Finally, to send Transactional Email, you need to use POST /api/transactional/send End point. The example API request is shared below which includes Email Message ID and the XML feed as parameters.

For the above setup, the transactional Email received in Inbox will look similar to screenshot shared below.

Additional Notes

1. The List Field value added in API request above under "message_dynamic_fields" will overwrite the value stored in List field of any contact while sending the Transactional Emails only. The original value stored in list field will still remain as it is after the API request.
2. You can also use IF-THEN-ELSE conditions in the email message and send dynamic content to end users based on the List field value either populated in API request or already stored in List.
