TikTok Posting API with TypeScript

TokPortal is programmable, organic social-media distribution infrastructure — The Human API. For TypeScript developers, it acts as the post-generation layer after your app creates videos: send media, metadata, target country, account rules, and schedule instructions; TokPortal routes the job to real physical smartphones with local SIM cards and native in-app posting.

This page is for developers, AI video tools, agencies, and technical marketers who need a working TikTok posting pipeline in Node.js. If you are comparing the official TikTok Content Posting API with real-device distribution, start with how to post on TikTok via API, then use this guide to build the TypeScript integration.

A minimal Node.js TikTok posting flow has four parts: create a campaign, upload the video asset, assign one or more TikTok accounts, then poll or subscribe to job status. TokPortal’s REST API and TypeScript SDK are documented at developers.tokportal.com.

TypeScript example:

import { TokPortalClient } from "@tokportal/sdk";

const tokportal = new TokPortalClient({
  apiKey: process.env.TOKPORTAL_API_KEY!
});

const campaign = await tokportal.campaigns.create({
  name: "spring-launch-us-tiktok",
  platform: "tiktok",
  targetCountries: ["US"],
  timezone: "America/New_York"
});

const asset = await tokportal.assets.upload({
  filePath: "./videos/product-demo-01.mp4",
  caption: "Testing the new drop in New York this week.",
  soundVolume: 80
});

const job = await tokportal.posts.create({
  campaignId: campaign.id,
  assetId: asset.id,
  accountSelector: { country: "US", niche: "ecommerce" },
  publishAt: "2026-03-18T14:30:00-04:00",
  options: {
    nativeAppPosting: true,
    locationTag: "New York, NY"
  }
});

console.log(job.id, job.status);

The important difference is where the final publish happens. Official APIs handle supported publishing surfaces; TokPortal routes eligible TikTok jobs through the real app on real devices, which preserves native app features such as sounds, location tags, and app-side editing when configured.

To schedule TikTok posts with TypeScript, store each video as a job with a publish timestamp, country, account selection rule, and retry policy. The scheduler should not be a loop that uploads the same asset repeatedly; it should be a queue with idempotency keys, webhook status, and per-account pacing.

Recommended scheduling object:

type ScheduledTikTokPost = {
  externalId: string;
  videoUrl: string;
  caption: string;
  platform: "tiktok";
  country: "US" | "GB" | "CA" | "DE" | "FR" | string;
  publishAt: string;
  accountPool: "brand" | "creator" | "local-market";
  idempotencyKey: string;
};

For visual workflows, developers often pair the SDK with TokPortal + n8n automation, TokPortal + Make visual workflows, or TokPortal + Zapier distribution triggers. Use those when your source of truth is Airtable, Google Sheets, a DAM, a CRM, or an AI generation queue.

There is no universal “TikTok Reels” object: TikTok publishes TikTok videos, while Instagram publishes Reels through Meta’s Instagram APIs and app workflows. The practical SDK pattern is to model one short-form video asset and fan it out into platform-specific publish jobs.

Cross-platform asset model:

const shortFormAsset = await tokportal.assets.create({
  sourceUrl: "https://cdn.example.com/clip-42.mp4",
  title: "clip-42",
  captions: {
    tiktok: "New launch test in Austin.",
    instagram: "New launch test in Austin. #reels",
    youtube: "New launch test in Austin. #shorts"
  }
});

await tokportal.distribution.createBatch({
  assetId: shortFormAsset.id,
  destinations: [
    { platform: "tiktok", country: "US", nativeAppPosting: true },
    { platform: "instagram", format: "reel", country: "US" },
    { platform: "youtube", format: "short", country: "US" }
  ]
});

If your TypeScript app generates videos with Runway, Sora, Veo, Kling, Pika, Captions, HeyGen, Arcads, Creatify, or Topview, this model lets you keep generation separate from distribution. The generator produces the file; TokPortal handles country-aware publishing and job status.

A production TikTok posting pipeline should be built like distribution infrastructure, not like a one-off upload script. The clean architecture is: content source, validation, asset storage, campaign rules, account selection, publish queue, webhooks, analytics, and finance reporting.

Pipeline shape:

• Source: AI video generator, editor export, creator submission folder, or CMS.
• Validation: file type, duration, aspect ratio, caption length, target market, and duplicate checks.
• Campaign rules: country, niche, account pool, publish window, and approval state.
• Distribution: TokPortal post jobs with native app posting enabled where needed.
• Observability: webhook events into Slack, Datadog, BigQuery, HubSpot, or your internal dashboard.

For a deeper build-out, use the batch processing guide for TikTok content automation and the TokPortal API + n8n pipeline guide.

Webhook-based posting is the right pattern once your queue has more than a few videos per day. Instead of polling every job, subscribe to post lifecycle events: accepted, asset_ready, scheduled, publishing, published, needs_review, failed, and analytics_ready.

Express webhook receiver:

import express from "express";
import crypto from "crypto";

const app = express();
app.use(express.json({ type: "application/json" }));

app.post("/webhooks/tokportal", async (req, res) => {
  const signature = req.header("x-tokportal-signature") || "";
  const payload = JSON.stringify(req.body);
  const expected = crypto
    .createHmac("sha256", process.env.TOKPORTAL_WEBHOOK_SECRET!)
    .update(payload)
    .digest("hex");

  if (signature !== expected) return res.status(401).send("invalid signature");

  const event = req.body;
  if (event.type === "post.published") {
    await markPublished(event.data.postId, event.data.url);
  }

  if (event.type === "post.failed") {
    await routeForReview(event.data.postId, event.data.reason);
  }

  res.status(200).send("ok");
});

Use the TokPortal webhook events reference when mapping event types to your database states.

The official TikTok Content Posting API is useful when your app fits its supported scopes, review process, media requirements, and publishing surfaces. Its biggest practical limitation for growth teams is that API publishing is not the same as native in-app posting: app-only features such as TikTok sounds, certain location behavior, and manual edits are not exposed the same way through developer endpoints.

TokPortal’s approach is different: the API controls the workflow, while the final action happens inside the real TikTok app on physical smartphones with local SIM cards and human-in-the-loop operation. That is why teams use TokPortal for distribution campaigns where geography, native sound usage, app-side editing, or multi-account pacing matter.

If your use case is a profile utility such as a TikTok profile viewer, TikTok profile picture download, TikTok profile picture downloader, TikTok pfp downloader, or a one-off search for a creator like “irynabunny,” this page is not the best fit. Those are utility intents. This integration is for businesses that need repeatable publishing infrastructure.

For API pacing and queue design, use the TokPortal API rate limits and optimization guide. For native sound constraints, read how TikTok sounds work with native in-app posting.
