## schedule_slideshow

**Schedule a slideshow.** Permission: `write`. Changes or removes saved work.

Put a slideshow on the Calendar at a later time, or move it, and optionally choose the brand's account groups it goes to: groupIds replaces the list, addGroupIds adds to it. This only plans the time and groups: it does not post. A post goes out when the owner sends it, or approves it for automatic posting, in Wavegrain; no tool sends or posts, and only a key the owner let approve may approve, with approve_slideshow. A time at or before now is refused. Moving an approved slideshow or changing its groups withdraws its approval, so the owner approves again in Wavegrain. The answer's composerUrl opens the Calendar composer, where a person approves it and chooses the networks and accounts.

| --- | --- | --- | --- |
| `slideshowId` | string | yes | up to 200 characters |

| `addGroupIds` | string[] | no | Adds groups and keeps the ones it already goes to. Use this for "also post it to group X". up to 10 items |

Returns: `slideshowId`, `scheduledFor`, `approvalWithdrawn`, `targets`, `warnings`, `groupIds`, `composerUrl`.

## schedule_slideshows

**Schedule several slideshows.** Permission: `write`. Changes or removes saved work.

Put up to 14 slideshows on the Calendar in one call, each with its time and optional account groups, as schedule_slideshow does for one. Every item is checked first, so one bad item schedules nothing. Each slot is a plan the user approves in Wavegrain; nothing is sent or posted. Moving an approved slideshow or changing its groups withdraws its approval.

| Input | Type | Required | Notes |
| --- | --- | --- | --- |
| `items` | object[] | yes | Each slideshow once, with its time and optional groups, for example the slots plan_week proposed. up to 14 items |

**Choose the opening hook.** Permission: `write`. Changes or removes saved work.

Put one of the slideshow's alternative opening hooks (`hooks` in get_slideshow) on its slide and save it, like picking a hook in the editor and pressing Save. Saving withdraws the slideshow's approval.

| Input | Type | Required | Notes |
