A simple scheduling flow

From content plan to live post in three steps

Your app sends the plan. Mallary waits, runs each platform job, and reports the result.

  1. 1

    Choose the channels

    Pick one or more connected platforms. Add your message, media, and any platform options.

  2. 2

    Set the publish time

    Send one exact timestamp, or send a local time with an IANA time zone such as America/New_York.

  3. 3

    Watch the jobs

    Check each job, list grouped posts, or use webhooks. Delete a pending grouped post before publishing starts.

Tools your scheduler needs

Exact publish times

Use a UTC or offset timestamp when your app already knows the exact moment.

Local time zones

Use a local wall-clock time and an IANA time zone when the audience cares about local time.

One grouped post

Schedule one post across many platforms and keep all platform jobs in one group.

Platform-specific content

Change captions, titles, post types, and other supported options for each destination.

Cancel pending posts

Delete a grouped post while it is still waiting and publishing has not started.

Status webhooks

React when a post is scheduled, published, partly published, or failed.

No Code? No Problem.

You don't even need to know what an API is. Just use your preferred tool, connect Mallary, and tell it what you want to post.

Social media scheduling API FAQ

Questions developers ask

Short answers about publish times, time zones, jobs, and plans.

What is a social media scheduling API?

A social media scheduling API lets your app set a future time for a social post. The API saves the post, waits for that time, and then sends it to each chosen social platform.

How do I schedule a post with Mallary?

Send your normal POST /api/v1/post request and add scheduled_at. You can send an exact timestamp with a time zone offset, or pair a local time with scheduled_timezone.

How does Mallary handle time zones?

You can send a local date and time with an IANA time zone such as America/New_York. Mallary turns it into UTC for the queue and returns the original scheduled_timezone when you read the grouped post.

Can one request schedule posts on many platforms?

Yes. Add any supported connected platforms to the platforms array. Mallary creates one job for each platform and keeps them together as one grouped post.

Can I cancel a scheduled post?

Yes. Call DELETE /api/v1/posts/{id} while the grouped post is still pending and publishing has not started.

How do I know when the scheduled post is live?

Check GET /api/v1/jobs/{id}, list grouped posts, or listen for webhooks. Finished jobs include a platform post ID and public URL when the platform provides them.

Which plans include API scheduling?

Scheduling is included with Starter, Pro, and Business plans. Paid plans can be tried free for 14 days.
