Build one integration
Send one request to Mallary instead of building and fixing a different posting flow for every social network.
One API for 10 social platforms

A simple posting flow
From file to live post in three steps
The API stays small, even when the platform work is hard. Mallary does the slow work after your request returns.
1
Upload your media
Ask Mallary for an upload URL, send the file, and get a public Mallary media URL. Skip this step for text-only posts.
2
Create the post
Send your message, platforms, media, and optional publish time to POST /api/v1/post.
3
Track each platform job
Poll a job, list grouped posts, or use webhooks. You can see what published and what needs attention.
Made for real apps
Post now or schedule
Publish at once or set a future time and time zone on paid plans.
Change text by platform
Start with one message, then add a custom caption or title for any platform that needs one.
Send images and video
Upload media once. Mallary checks each platform rule before it adds the post to the queue.
Use safe retries and queues
Long uploads run in the background. Mallary retries safe failures without making your app wait.
Work with many profiles
Use profile_id when a user has more than one set of connected social accounts.
React with webhooks
Start your next step when a post is published, scheduled, partly published, or failed.
Social media posting API FAQ
Questions developers ask
Short answers about posting, media, schedules, and job status.
What is a social media posting API?
A social media posting API lets your app publish content with code. Your app sends the text, media, and target platforms. The API sends the post to each connected social account.
Which social platforms can Mallary post to?
Mallary can post to Facebook, Instagram, LinkedIn, YouTube, TikTok, Pinterest, Reddit, Threads, Snapchat, and X. Each platform has its own media and post rules.
Can I schedule posts with the API?
Yes. Paid plans can send scheduled_at with an exact time. You can also send scheduled_timezone when you want Mallary to use a local time zone.
Can each platform use different text?
Yes. Send one main message for every platform, then use platform_options to set a different message, title, post type, or other supported option for one platform.
How do I know when a post is live?
The create request returns one job ID for each platform. Check GET /api/v1/jobs/{id}, list your grouped posts, or use a webhook. Finished jobs include the platform post ID and public URL when the platform provides them.
Does my app need to handle social network tokens?
No. Users connect their accounts in Mallary. Mallary handles the saved connection, token refresh, API changes, queues, and platform calls.
