Create a webinar by pasting JSON

A webinar's plan can be written as one JSON document and pasted into Magpie. New webinar → Paste JSON will create a draft webinar from it. On a draft, More → Import JSON will replace the draft's plan with it. Export JSON, in any webinar's More menu, will download its plan in the same format. An export will import back as the same plan, as long as its start is still in the future. A choice question needs at least 2 options for its export to import back.

Use Copy the prompt in the import box to copy these instructions for an assistant you use. The assistant will ask you for what it needs, then write the document.

Importing is all or nothing. Magpie will check the whole document before it saves anything, and will name a mistake by its place in the document, such as "polls[0].options" has 9 values; the limit is 8. An imported webinar is a draft: its registration page will open only when you publish it.

Replacing a draft's plan will change its title, start, time zone, length, description, email messages, registration questions, polls, questions ready for the Q&A, resources and call to action, and will replace the speakers from outside your team. Everything else on the draft will be kept: its hosts, co-hosts and moderators, members of your team who speak, the registration page address, the cover picture, who can register, the capacity, the reminders and the breakout rooms. Only a draft can be replaced; to change the plan of a published webinar, duplicate it and import into the copy.

The document never holds attendees. Speakers in it will be added by name, without an email address. To send a speaker their personal link, add their email address on their page; in a draft, the link will be sent when you publish.
