Building on native comment APIs

Every network has different comment permissions, threading behavior, moderation rules, and response limits.

Support teams need context from the original post, not an isolated list of comments.

Comment importing, replying, and moderation are usually separate native API projects.

What bundle.social handles

Use one comment workflow for supported platforms instead of building every response path separately.

Keep comments connected to posts, imported history, and the team reviewing them.

See platform gaps clearly before your team builds automation around them.

Comment workflows need platform context

Social comments look similar in a dashboard, but each network has its own rules for replies, moderation, threading, and access. bundle.social leaves those limits visible while giving your team one place to work.

Workflow

How it works

Connect accounts, import comments from supported platforms, and reply or moderate from one API endpoint.

Connect accounts once

Connect each social account once and the account mapping stays ready for comment imports and replies.

Import comments

Trigger a comment import for supported platforms. Imported comments arrive with full post context attached.

Reply, triage, and manage

POST a reply to any imported comment using one endpoint. Triage, moderate, and track replies from the shared dashboard.

Product architecture

Build social media workflows without rebuilding every platform

Social media comments API for replies, moderation, and campaign context

A social media comments API becomes important once publishing is no longer the whole workflow. Agencies, SaaS products, creator tools, and support teams need imported comments, replies, thread context, moderation states, and the campaign that generated the conversation. Building each of those paths natively means a separate project per network, with different permissions and different threading behavior.

bundle.social keeps comments in the same workflow as the posts that created them. Your product can import comments from supported platforms, reply through one endpoint using the fetched comment reference, and let marketing or support teams triage from the shared dashboard. Post context travels with each comment instead of being reconstructed later.

Comment support is platform-specific and should stay visible

Comments look similar in a dashboard and behave differently underneath. YouTube exposes deep threads, Instagram and Facebook depend on Meta permissions and account type, Reddit follows community rules, TikTok read and manage capabilities are narrower than classic public comment APIs, and X is not part of the comment import list at all.

Flattening those differences into one promise usually produces moderation features that quietly do nothing on half the connected accounts. bundle.social shares the workflow and keeps the capability explicit, so product teams can tell users what each connected account supports rather than discovering the gap through support tickets.

Comments connected to the posts that caused them

A reply is rarely only a support action. It is public, attached to a campaign, and often answerable only with the context of what the post promised. When conversations live in one tool and content lives in another, the person replying works without that context and reporting never connects engagement to the content that caused it.

Scheduled posts, published status, imported history, analytics, and comments live in the same workspace. Agencies can review client replies against the original brief, support teams can escalate without screenshots, and product teams can see which formats generate conversation instead of only which formats generate reach.

Capabilities

Built for comment workflows across social platforms

One API to import, reply to, and manage social comments, with full context from the original post.

Import comments across platforms

Fetch comments from YouTube, Instagram, Facebook, and other supported channels into one workflow without building separate integrations.

Reply from a unified endpoint

Post replies using a single API call regardless of which native platform the comment came from.

Thread context preserved

Each imported comment carries the parent post reference so replies always have full context.

Platform-aware moderation

Comment permissions, threading rules, and moderation limits stay visible per network so your team knows what each platform actually allows.

Team review in the dashboard

Marketing and support teams can read, triage, and reply without making API calls directly.

Connected to post history

Comments tie back to the scheduled and published posts your team created in bundle.social for full campaign context.

Developer example

Reply to an imported comment

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

Honest limitations

Twitter/X is not included in the current comment import platform list.
TikTok comment read and manage capabilities are more limited than classic public comment APIs.
Moderation actions depend on what each native platform exposes.

Guarantees

Developer-first infrastructure

Visible post status

Track scheduled, processing, posted, retrying, and error states per post.

Verbose errors

When native APIs fail, we return human-readable error messages and actionable recovery steps.

Flat pricing

No per-post counting. Predictable pricing for teams managing many users, workspaces, and connected accounts.

Same-day support

Direct access to the engineers building the API. We respond to technical issues the same day, sometimes the same hour.

FAQ

Questions developers ask before building

Which platforms can use comment workflows?

bundle.social includes comment-related workflows for YouTube, Instagram, Facebook, Threads, LinkedIn, Reddit, Mastodon, Bluesky, and TikTok. X/Twitter is not supported. Platform-specific limits apply.

Can I reply to comments through the API?

Yes, for supported platforms and permissions. The exact payload and behavior depend on the native platform.

Can I build moderation workflows?

Yes, but moderation actions vary by platform. bundle.social helps organize the workflow; it does not override native platform rules.

How does this help agencies?

Agencies can keep replies, context, and post performance next to the original scheduled content instead of jumping between native dashboards.
