Follow

Hi Team,

We are trying to incorporate in app automation messaging with handlebars for our app for that at air ship dashboard the message trigger is set to an custom event and its properties we are using in automation message with handlebar syntax.

But the dynamic content from custom event properties are not updating while the automation message is presented in app. Please help us to resolve the issue.

Note: while using attributes inside handlebars the message is updated correctly. but for custom events its not updating.

Below are the steps we followed

In Dashboard message creation.

In APP notification we are getting without the handle bar contents:

In code we are using retail browsed custom template and also another custom event.

            let retailTemplate = UARetailEventTemplate.browsedTemplate(withValue: 100)

            retailTemplate.category = "drugs"

            retailTemplate.identifier = drug.gsn?.stringValue ?? ""

            retailTemplate.eventDescription = "Low top"

            retailTemplate.transactionID = "13579"

            retailTemplate.brand = "SpecialBrand"

            retailTemplate.isNewItem = true

            let retailEvent = retailTemplate.createEvent()

            retailEvent.track()
