Loyalty Tactics use the External event transactional entry point in the Automation Center.

Here contacts can enter a program if they are returned by an API call containing the same external event (you must first create the API call before you can use this node).

• If you include external data in the external event API call, this external data will remain available for that contact throughout their journey through the program and can be used to personalize further emails.
• Programs that start with this entry point follow the ignore opt-in rules for transactional programs. If you create a program that starts with one of these entry points, the first email in the program will be sent to all participating contacts regardless of their opt-in status (i.e. opt-in can be empty or FALSE).
• External events may be used in as many active programs as you like.

You can create Automation Center programs that trigger Loyalty actions or assign rewards with this node.

Using the Loyalty Trigger node, you can build sophisticated automations with Emarsys in Interactions. You can quickly react to event related to your contacts engaging with your brand and involve them with Loyalty. For more information, see Channel nodes.
