Social Media API for AI Agents: Post to TikTok, Instagram, Facebook and Threads

A social media API lets one integration publish posts to multiple platforms instead of building separate connectors for each one. IMMA AI's social media API sends a single request to TikTok, Instagram, Facebook Pages and Threads, checks each platform's limits first, and requires human approval before anything reaches TikTok.

Can one API post to TikTok, Instagram, Facebook and Threads?

Yes. IMMA AI exposes one REST API and one MCP server that cover all four networks, so an agent or backend only learns one request shape instead of four separate developer platforms. Under the surface, each publish call is translated into the calls that Meta's Graph API and TikTok's Content Posting API expect: a Facebook Page post through pages_manage_posts, an Instagram post through instagram_business_content_publish, a Threads post through threads_content_publish, and a TikTok video through the Content Posting API. The response comes back in one consistent shape regardless of platform, with a status field, the live URL once published, and any error explained in plain language. A single idempotency key per post also means a retry from a flaky network never creates a duplicate post on any of the four platforms.

How does a social media API handle TikTok's approval requirements?

TikTok requires the account owner to preview a post and choose its privacy setting before it can go live through the Content Posting API, and that consent has to happen in a real interface, not just an API call. IMMA AI's social media API handles this by generating a hosted approval page for every TikTok post: the owner opens a link (commonly shared over Telegram), sees the exact video, caption and thumbnail, and picks who can view it from TikTok's own privacy options, with no default selected. Comment, Duet and Stitch toggles start off. Only after that explicit confirmation does the API call TikTok's Content Posting API to publish or queue the draft. This keeps an AI agent free to draft posts continuously while a human stays the only one who can make a post public.

What are the platform limits for a unified social media API?

Each network enforces its own posting limits, and a unified social media API has to check them before queuing a post rather than after a rejection. Instagram allows 100 posts through the API per account in a rolling 24 hour window, with a carousel counted as one post of up to 10 items. Threads allows 250 posts, 1,000 replies and 100 deletes per account in 24 hours, and exposes a GET /threads_publishing_limit endpoint to check the remaining quota. TikTok caps creators at roughly 15 posts per day and rate limits each access token to 6 requests per minute. IMMA AI checks these limits before a post is queued so an agent gets a clear "quota reached, try again later" response instead of a platform level failure.

Platform limits at a glance

Platform	Posting limit	Notes
Instagram	100 posts per account per 24 hours	Carousel (up to 10 items) counts as one post
Threads	250 posts, 1,000 replies, 100 deletes per 24 hours	Check remaining quota via GET /threads_publishing_limit
Facebook Pages	Covered by standard Graph API rate limits	Minimum scopes: pages_show_list, pages_read_engagement, pages_manage_posts
TikTok	About 15 posts per creator per day	Token rate limit is 6 requests per minute

How it works

An agent or workflow calls the IMMA AI social media API (or its MCP server) with a caption, media and target platforms. IMMA AI validates the media against each platform's format rules, queues Meta posts directly, and for TikTok generates an approval link for the account owner. Once approved, or immediately for Meta platforms, IMMA AI publishes the post and sends a webhook back with the live link and the first available stats.
