Hide, retime or edit a slide, such as changing the price on a live slide

Changes one slide: how long it shows (durationSeconds, 1-300) and whether it is hidden (hidden). Use it to hide or show a slide, or make it stay longer or shorter. A dynamic slide also takes templateId, sourceId, fieldMapping (generated when the template or source changes without one), overrideData (merged into the slide's own values, a null value removes one: use it to change a price or a line of text on a slide not fed by a Push source) and countdown ({overlayId, mode: fixed|daily|source, targetTime|dailyTime|sourceField}, [] clears it). Text inside an uploaded PowerPoint cannot be edited: replace the file instead. To expire or take down a slide on a date, set a date condition via PUT /v1/slides/{id}/conditions instead of scheduling a delete. Omitted fields are left unchanged.
