Blog2Social Social Media API
One Social Media Publishing API. Multiple Ways to Build, Connect and Automate.
Connect accounts and publish content across 25 social networks through one unified infrastructure. Build directly with the REST API or official SDKs, connect AI assistants and agents through the hosted Blog2Social MCP Server, or create automated publishing workflows.

How the REST-API Works
Publish your first social media post in less than 5 minutes
Request your API Key, authenticate a user, connect a social media account, and publish your first post through the Blog2Social REST-API.
Authentication model
The API uses a two-layer authentication model:
service_token = your application access_token = your userAPI Quick Start Workflow
Follow these five steps to connect users and social media accounts and publish your first post.
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.
AI & MCP
Connect AI Assistants and Agents to Social Media
Blog2Social MCP Architecture
In short: your AI application connects to the hosted Blog2Social MCP Server, users authorize access through OAuth, and the AI can work with available Blog2Social tools.
Generating social media content is only one part of the workflow. With the hosted Blog2Social MCP Server, compatible AI applications can interact with Blog2Social through standardized tools and turn natural-language instructions into social media actions.
No local Blog2Social MCP installation is required. Connect a compatible AI application to Blog2Social and work with available functionality for accounts, networks, content and publishing.
Hosted MCP Server
Blog2Social MCP is ready to use without any local installation.
OAuth Authentication
Users authorize access through OAuth instead of sharing their Blog2Social password with the AI client.
Standardized Tools
AI applications can work with available Blog2Social functionality for accounts, networks, content and publishing.
Natural-Language Workflows
Use Blog2Social through AI instructions instead of manually implementing each API call in the AI client.
