Example: campaign element task command for a trigger (customer event type)

Sample

Here is the task command implementation code for an example trigger. In this example, an external system detects credit fraud. The external system can detect credit card fraud, or credit account fraud. The external system sends a message to the marketing services that one of these occurrences of fraud occurred for a customer. By using this customized trigger, a Marketing Manager would be able to create a Dialog activity to specify how to follow up with the customer in this situation (for example, send a mobile text message or an email, depending on their level of coverage, and then send a follow-up message after a certain time). The eventType parameter can be one of (CreditCard, CreditAccount) to allow different handling, depending on the type of fraud that occurred.

This task command example defines the validateParameters method to validate the trigger parameters and return any errors.
