Scheduling to X (Twitter) through SkedCast's API#
SkedCast's /v1 REST API schedules text, image, video, GIF, poll, and thread to X (Twitter) the same way it does every other platform: one POST https://api.skedcast.com/v1/posts call with a content caption and a targets block naming the connected accounts.
You need an X account connected through X's login, connected once through the console or through a connect link that POST /v1/clients/{id}/connect-invites creates.
The request is one contract for every connected platform. The fields that are specific to X (Twitter) are listed below.
Example: schedule a post to X (Twitter)#
{
"clientId": "00000000-0000-4000-8000-000000000001",
"content": "New: scheduled threads. Details in the replies.",
"targets": { "mode": "accounts", "accountIds": ["00000000-0000-4000-8000-000000000002"] },
"schedule": { "type": "at", "scheduledAt": "2030-01-15T15:00:00Z" }
}X (Twitter) facts#
| Fact | Value |
|---|---|
| Max caption length | 280 characters |
| Media per post | up to 4 images, or one video/GIF, per post; threads chain multiple posts. |
| Native platform scheduling | No. SkedCast holds the timer and publishes at the scheduled time. |
| SkedCast's default pacing | 100 / day, with at least 5 min between posts, per account. This is SkedCast's per-account pacing, not X (Twitter)'s own published limit. See the rate limits reference. |
Published-post URL (permalink) | https://twitter.com/i/web/status/{id}, always returned once the post is published. |
Reading status and results#
GET https://api.skedcast.com/v1/post-targets/{id} returns the X (Twitter) target's status (for example scheduled, on_hold, published, failed or missed). Once the post is published, externalId and permalink point at the live post (see the table above).
on_hold:holdReasonsays why (pacing, a platform limit, media still processing, your plan, or a channel that needs reconnecting) andretryAtsays when the next try is.missed: the scheduled time passed while the post waited.outcomeReasonsays why; reschedule it.failed:failureReasonsays why.

FAQ
- Can I schedule an X thread through the API?
- Yes. Add a thread object with 2 to 50 segments to POST /v1/posts; each segment has a content text and optional mediaIds. SkedCast publishes the segments as a reply chain on X and Threads. Other platforms in the same post receive only the first segment.
