Zapier + Instagram: Automate Posting With the IMMA AI Social Media API

Zapier and Instagram can already be connected through Meta's own app, but a Zap that also needs TikTok, Facebook Pages or Threads usually means stitching together several separate integrations. IMMA AI gives a Zap one Webhooks action that posts to all four platforms through a single social media API, with TikTok's required approval step handled automatically.

Can you schedule Instagram posts with Zapier?

Yes, through a Zap built on IMMA AI's social media API. A trigger step such as a new row in Google Sheets, a new item in Airtable, or a scheduled Zap can feed a caption and image or video URL into a Webhooks by Zapier action configured to call POST /v1/posts, with instagram listed as the target platform. IMMA AI validates the media against Instagram's carousel and format limits before queuing the post, and the response includes a status field and, once published, the live post URL plus the first available insights. Because the same endpoint accepts multiple target platforms in one request, the same Zap can also post the identical content to Facebook Pages or Threads by adding those platforms to the request body, instead of building a separate Zap and separate credentials for each network.

How do you connect Zapier to a unified social media API?

The connection is a standard Webhooks by Zapier action rather than a dedicated IMMA AI app, at least while the integration is in preview: the action's URL points at IMMA AI's /v1/posts endpoint, the headers carry a workspace API key, and the body is built from the Zap's trigger data using Zapier's field mapping. For platforms that publish immediately, such as Instagram, Facebook Pages and Threads, the Zap can end there or add a follow-up step, like sending a Slack message with the new post URL. For a TikTok target in the same request, IMMA AI returns an approval.url instead of a published status, since TikTok requires the account owner to review and approve every post themselves; a Zap can send that link over email or Telegram as its next step, keeping the automation compliant without the Zap needing any TikTok-specific logic.

Does Zapier support TikTok's approval requirements?

Not on its own, which is exactly why routing a TikTok target through IMMA AI matters for a Zap that touches TikTok at all. TikTok's Content Posting API requires the account owner to preview the exact post and choose a privacy setting through a real interface before anything can go live, a requirement no webhook or background Zap step can satisfy by itself. When a Zap sends a TikTok target to IMMA AI, the response is never a published status; it is always an approval.url pointing at a hosted page where the owner sees the video and caption, picks a privacy level with no default preselected, and leaves Comment, Duet and Stitch toggles off unless they choose otherwise. Only that human decision triggers the actual call to TikTok's Content Posting API. A Zap's job stops at handing off a well-formed draft and forwarding the approval link, so it never needs to implement TikTok's consent screen or store TikTok credentials.

Zapier steps for posting to Instagram through IMMA AI

Step	Zapier action	What it does
1	Trigger (Sheets, Airtable, Schedule, Form)	Supplies caption and media for the post
2	Webhooks by Zapier: POST	Calls IMMA AI's /v1/posts with target platforms
3	Filter (optional)	Splits the Zap by response status
4	Notification action	Sends a TikTok approval link if one was returned

How it works

Whether a post originates from a Zap, an n8n workflow, a Make scenario, or IMMA AI's own dashboard, it passes through the same social media API, the same platform limit checks, and the same TikTok approval requirement. See the social media API page for the full request shape, or Instagram posting API for Instagram-specific limits and permissions.
