Is this TikTok’s official Content Posting API?

Yes. postpeg posts through TikTok’s Content Posting API. You call one postpeg endpoint instead of handling TikTok’s upload, status polling and token refresh yourself.

Can I post photo carousels to TikTok?

Yes. Send up to 35 images (never mixed with a video) and postpeg makes a TikTok photo post. TikTok fetches the images from postpeg’s verified media address, so use a carousel’s slides from POST /v1/tiktok/carousels or files uploaded to postpeg, as JPEG or WebP. A video is one file, sent by public https URL.

Which privacy settings can I use?

platform_options.tiktok.privacy takes public, friends, followers or private, and defaults to public. It must be one the creator’s account allows, which GET /v1/accounts/{id}/tiktok/creator-info returns.

Can the same request post to Instagram or YouTube too?

Yes, if you add your own Zernio key: other networks run on your Zernio account (its first 2 accounts are free). The same request then goes to all of them.

TikTok Posting API

Post and schedule TikTok videos with one API call

What the TikTok posting API handles

Checked before it’s sent. TikTok takes 1 video, or a photo post of up to 35 images, and captions up to 2,200 characters. A post that breaks a rule is refused with every problem listed, and nothing is uploaded.
Photo carousels. POST /v1/tiktok/carousels makes the slides, caption and hashtags; its media goes straight into POST /v1/posts as a photo post. TikTok fetches photos only from postpeg’s verified media address, so photo posts use a carousel’s slides or files uploaded to postpeg, as JPEG or WebP.
Now or scheduled. Leave out scheduled_at to post now, or set it up to a year ahead. Cancel until it goes out.
TikTok’s own options. Privacy, comments, duet and stitch, and the commercial content disclosures (your brand, branded content, AI-generated), in platform_options.tiktok. The allowed privacy levels come from GET /v1/accounts/{id}/tiktok/creator-info.
Retries without duplicates. A bad minute at TikTok is retried with backoff; a post that may already be live is marked failed, never sent twice.
Analytics. Views, likes, comments and shares per post through GET /v1/posts/{id}/analytics, where TikTok grants access.

Connecting a TikTok account

Create a connect link with POST /v1/accounts/connect and send the account’s owner to it. They approve access on TikTok’s own screen; your app never sees their password. Accounts connected through postpeg count toward your plan (3 on the trial). See profiles and accounts.

Post, then find out if it worked

Add inspired_by (the TikTok video you learned from) and niche_id to a post, and postpeg measures it at 24 hours and 7 days against that niche’s week: GET /v1/posts/{id}/benchmark says which percentile it reached. See TikTok competitor analysis for where the ideas come from.
