Messages API model does not match documentation

[l-dobrev-cch]

Using Messages API to send messages with fail-over is not possible due to incomplete model classes.

Version: infobip-api-java-client:4.3.2

Some classes lack required attributes, which interferes with using Messages API corectly.

• com.infobip.model.MessagesApiFailover

  • lacks content attribute
  • this disallows using failover with different channels.
  • the API documentation does not state that content is required for fail-over
  • this has been confirmed with customer support while resolving an issue

• com.infobip.model.MessagesApiTemplateMessage

  • lacks failover attribute
  • this disallows using failover with initial WhatsApp messaging

• com.infobip.model.MessagesApiTemplateMessage.destinations

  • the attribute is defined as list of ...MessagesApiToDestination
  • this disallows setting proper destinations for fail-over with ...MessagesApiTemplateMessage
  • suspected need to use ...MessagesApiMessageDestination instead

The expected behaviour is a successful delivery of a :

• WhatsApp template message (template: authentication) to a user by their Phone Number
• Viber fail-over with plain text message to the same user by their Phone Number
• SMS fail-over with plain text message to the same user by their Phone Number

This issue is just about the inconsistent API model classes, and does not necessarily claim that the actual service will work as intended.

The issue seems to have been resolved in #46 and the related version 4.4.0
