That costs time, resources, and effort. The Blog2Social API gives you one interface to connect accounts, publish content, and manage multi-network posting workflows across all social media platforms.

API Quick Start Workflow

Follow these five steps to connect users and social media accounts and publish your first post.

5 steps

Authenticate the user

Send your service_token to POST /user/auth. Save the returned access_token and refresh_token for future requests made on behalf of the user.

Get available social networks

Call POST /network/list with the service_token and access_token. Select the required network_id from the available profiles, pages, and groups.

Connect a social media account

Send the selected network_id and its matching network_type_id to POST /network/add. Use 0 for a profile, 1 for a page, or 2 for a group.

Redirect the user to the returned auth_link to complete the connection.

Retrieve connected accounts

Call POST /user/auth/list and save the returned client_user_network_id. This identifier selects the connected account that will receive the social media post.

Publish your first post

Send your content to POST /network/post/create together with the selected client_user_network_id. Choose postFormat 0 for a link, 1 for an image, or 2 for a video.

A response with error: 0 confirms that the post was published successfully.

FAQ

Frequently Asked Questions about the Blog2Social API

How does the Blog2Social API differ from directly using each social network’s API?

Instead of managing separate authentication flows, payload formats, publishing logic, and response handling for every platform, your team works with one unified interface. This can reduce implementation time, lower maintenance effort, and make your product architecture easier to scale when additional networks are needed.

What should a product team evaluate before integrating the API?

The most important factors are the target networks, the content types you want to support, how users will connect their accounts, and how your application should handle returned post URLs and status responses. Planning these workflows in advance helps ensure a smoother user experience and a cleaner backend integration.

Why do custom social media API integrations often fail?

Each social media platform requires its own integration — with separate rules, authentication flows, and error handling. When a platform changes its API requirements, integrations can break, forcing your team to spend time fixing issues instead of improving the actual product.
With one unified interface for all social networks, Blog2Social handles authentication, formatting adjustments, and API updates — so your team no longer has to maintain these integrations manually.

Which social media networks does the Blog2Social Social Media API support?

The Blog2Social API currently supports 25 social networks, including Instagram (Business Accounts), LinkedIn (Profiles & Company Pages), Facebook (Profiles, Pages & Groups), TikTok, X (Twitter), Pinterest, YouTube, Reddit, Medium, XING, and more.
You can publish to multiple networks simultaneously with a single API request — without separate authentications or platform-specific SDKs.

Why are post URLs important in an API workflow?

Returned post URLs are useful far beyond simple confirmation messages. They allow you to show users exactly where content was published, store links in reports or audit trails, open live posts directly from your interface, and trigger follow-up actions such as moderation, campaign tracking, or customer support workflows.

Why do developers use this kind of API?

Reduce integration complexity:
Each social network has its own rules, endpoints, and connection flow. A unified API reduces how much of that complexity your own team needs to manage directly.

Save engineering time:
Instead of investing development capacity into multiple social API integrations, your team can stay focused on the core product.

Standardize your workflow
Move from many platform-specific processes to one publishing workflow for tokens, posting, and response handling.

Build reliable user experiences
Use structured results, publishing URLs, and explicit error codes to show users what happened after each post.

What makes a social media API integration easier for end users?

For users, the biggest advantages are a simple account connection flow, clear publishing feedback, and transparent results. When your product guides users through account authorization, clearly displays publishing status, and provides direct links to published posts afterward, the integration feels reliable and significantly more user-friendly.

How much does the Blog2Social API cost — and how does billing work?

The Blog2Social API uses usage-based pricing with no fixed monthly fees or subscriptions.
The Standard plan starts at $0.02 per post and includes access to 11 standard social networks. The Premium plan starts at $0.05 per post and provides access to additional premium networks such as Reddit, TikTok, YouTube, Medium, and X.
There are no setup fees, no minimum contract terms, and no hidden costs. Billing is based entirely on actual usage — you only pay for posts that are actually published.

Ready to implement social media publishing directly into your application?

The Blog2Social API helps you turn publishing into a structured, scalable feature without rebuilding the same infrastructure for every platform.
