Bulk Social Media Posting

Bulk social media posting API for high-volume publishing

Create and schedule thousands of social media posts through API loops or CSV import, with per-post status tracking so failures do not block the whole run.

Managing bulk posts natively

Posting across many teams or platforms means building a loop, managing errors, and retrying failures yourself.
Bulk scheduling across multiple clients adds account-switching, auth management, and report aggregation complexity.
Agencies and AI content tools often ship bulk posting as an afterthought, then find it breaks under load.

What bundle.social handles

Create posts one at a time in a loop using the same API endpoint. No special bulk mode needed.
Status tracking, retries, and error states are exposed per post so failures do not cascade.
Schedule bulk campaigns across teams and platforms in the same dashboard review workflow.

Bulk posting is just scheduling at scale

bundle.social's post API is designed to handle volume. Loop through your campaign plan, create each post, and check status from the same dashboard your team already uses. For large runs, limit concurrency and space requests so platform and API rate limits stay predictable.

Workflow

How it works

Connect accounts once, then create and schedule posts with channel-specific fields from one API.

01

Create an API key

Generate an organization API key in the dashboard and use it with the x-api-key header.

02

Connect accounts

Connect each social account once. bundle.social keeps the account mapping ready for future posts.

03

Create or schedule posts

Send one request with the publish date, selected channels, and the fields each platform needs.

Bulk social media posting API for high-volume campaigns

A bulk social media posting API becomes important when content creation is no longer a one-post workflow. Agencies, AI content tools, franchise marketers, media teams, and multi-account products often need to schedule hundreds or thousands of posts while keeping each post independently trackable. The dangerous version of bulk posting treats the whole run as one giant job where one failure can make the result hard to reason about.

bundle.social approaches bulk publishing as scheduling at scale. Your product can loop over campaign rows, generated posts, location updates, or client calendars and create tracked post objects through the same endpoint used for normal publishing. Each post keeps its own account context, platform payload, scheduled date, media references, status, and error state.

Per-post status is what makes bulk publishing supportable

High-volume posting fails in ordinary ways: a media file is invalid, a token expires, a platform rejects a field, an account loses permission, or a video is still processing. In a bulk run, those ordinary failures become painful unless every post can be reviewed and retried separately.

With bundle.social, failed posts do not have to block the rest of the campaign. Operators can inspect row-level or post-level failures, fix the payload, requeue individual posts, and keep successful scheduled content intact. That makes bulk workflows practical for real teams instead of only clean demos.

Bulk workflows for AI tools, CSV imports, and agency calendars

Bulk publishing shows up in different product shapes. An AI tool may generate many platform variants, a CSV import may create one post per row, an agency may schedule client calendars in batches, and a franchise system may distribute local updates across many locations. All of those workflows need controlled concurrency, workspace context, and platform-specific validation.

The useful API design is to keep the bulk layer simple while preserving the same primitives as single-post publishing. Upload assets first, create tracked posts with the right teamId and platform data, space requests to respect rate limits, then use status and analytics workflows after publishing. That keeps volume from turning into an opaque queue.

Capabilities

Built for bulk social posting at production scale

One endpoint, looped. Per-post status, error isolation, and multi-account support built in.

Loop-based volume posting

Send one request per post in a loop using the same endpoint your dashboard uses. No special bulk mode or batch API needed.

Bulk CSV import

Upload a CSV where each row becomes one scheduled post. Failed rows surface their own errors and do not block the rest of the import.

Per-post status isolation

Each post tracks its own scheduled, processing, posted, and error states so a single failure does not cascade through the batch.

Multi-account scheduling

Route posts to different social accounts per request without managing separate auth connections or API credentials.

Parallel platform targeting

A single post payload can target multiple platforms in one call so bulk volume does not multiply your request count.

Dashboard review for teams

Marketing and account managers can review bulk campaigns and approve drafts without making API calls directly.

Retry and error visibility

Failed posts surface in the status workflow so your team can fix and requeue without losing context or rebuilding the batch.

Developer example

Schedule a batch of platform-specific posts

Examples use bundle.social's public API shape: API key authentication, a post date, selected social account types, and platform-specific data.

1const posts = [2  { platform: "INSTAGRAM", text: "New drop is live.", uploadIds: ["upload_img_1"], type: "POST" },3  { platform: "TIKTOK",    type: "VIDEO", uploadIds: ["upload_vid_1"], privacyLevel: "PUBLIC_TO_EVERYONE" },4  { platform: "LINKEDIN",  text: "We shipped a new product today. Here is what changed." },5  { platform: "TWITTER",   text: "Live now - link in bio." }6];78const results = [];910for (const { platform, ...data } of posts) {11  const response = await fetch("https://api.bundle.social/api/v1/post", {12    method: "POST",13    headers: {14      "x-api-key": process.env.BUNDLE_SOCIAL_API_KEY,15      "Content-Type": "application/json"16    },17    body: JSON.stringify({18      teamId: "team_123",19      postDate: "2026-05-14T10:00:00.000Z",20      status: "SCHEDULED",21      socialAccountTypes: [platform],22      data: { [platform]: data }23    })24  });2526  results.push(await response.json());27}

Honest limitations

  • Rate limits apply per API key. Space high-volume bulk operations across time to avoid hitting platform or API limits.
  • Each post still requires platform-specific data for channels with unique content models.
  • Media should be uploaded before bulk post creation so upload IDs are ready to reference.

FAQ

Questions developers ask before building

Is there a dedicated bulk post endpoint?

For API-driven runs, use the standard POST /api/v1/post endpoint in a loop. For spreadsheet-driven workflows, use the CSV import flow so each row becomes its own scheduled post.

Can I bulk schedule posts from a CSV?

Yes. CSV import lets teams upload rows of social posts, map fields, and review row-level failures without blocking the rest of the import.

How do I handle failures in a bulk run?

Each post returns its own status. Check the response for each request and retry failed posts individually rather than re-running the entire batch.

Can I bulk-schedule to multiple platforms at once?

Yes. Each post request can include multiple socialAccountTypes and platform-specific data blocks in a single call.

Is this useful for AI content tools?

Yes. AI tools that generate campaign content can call the post API in a loop for each piece of content without needing a special bulk mode.

What rate limits apply?

Rate limits depend on your plan. For high-volume use cases, limit concurrency, space requests across time, and contact the team to discuss volume needs.
