While importing tickets from another Zendesk into my new account, I sorely missed examples in the API documentation for the following cases:

• Ticket Import API: A sequence - what do you do when, which steps are dependent on others
• Ticket Import API: Attachment import for tickets to be imported
• Attachments or Ticket Comments API: An example on how to find and create inline attachments (i.e., screenshots in a ticket body)
• Ticket Import API: An example including the import of a complete ticket with several comments, attachments inline and attached to the end, etc. etc.
• Some general information outlining limitations of the API regarding import of merged tickets.
• An API to reserve a ticket's ID which will be imported in the future, and an extension to the import API to allow to set the previously reserved ticket ID. Use case: import of merged tickets.
  I know, migration from ZD to ZD might not be the main business.
