In addition to manually copying templates, or using the Import Template functionality in the Piano dashboard, you can also create a small script using our API to do this.
This API call will get the information about the Template from the specific AID:
https://api.piano.io/api/v3/publisher/offer/template/update?aid=XXXXXX&name=XXXXXX&offer_template_id=XXXXXX
You can then pass the information to the new AID using this call:
https://api.piano.io/api/v3/publisher/offer/template/updatefull?aid=XXXXXX&name=XXXXXX&content1_value=<div>asdfasdfasdf</div>&offer_template_id=XXXXXX&category_id=offer&content1_type=html&action=save&version=1
More information about the API call is available here.
All available base URLs for Production are listed here.
