SocialAPI.ai is a REST social media API you call from n8n with the HTTP Request node. Add your API key once as an n8n credential, then read comments, send DMs, publish posts, and reply to reviews across eight networks inside any workflow, with no per-platform OAuth setup.
Wiring each platform into n8n means separate OAuth apps, custom rate-limit handling, and a different response shape per network before a workflow can do anything useful. SocialAPI.ai sits behind one HTTP Request node: authenticate once with a header credential and every network is reachable through the same endpoints with normalized JSON that n8n expressions can read directly.
Call any endpoint from n8n with a single header-auth credential, no community node required.
List, reply to, hide, and like comments across all connected platforms in a workflow.
Read conversations and send replies from a workflow step.
Create and schedule posts across every network from one node.
Trigger an n8n workflow the moment a new comment, DM, or mention arrives.
Use the HTTP Request node

Add a header-auth credential with your API key, then point the HTTP Request node at any SocialAPI.ai endpoint. The same setup works for reading and for writing across every platform.
SocialAPI.ai works with the built-in HTTP Request node, so there is nothing to install or self-host. Create a header-auth credential with your API key once, reuse it across every node, and you can call any social endpoint from any workflow.
Because the API normalizes Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads, a single workflow can fan out across all of them without branching logic per platform. The same request shape returns the same JSON, so your n8n expressions stay simple.
Register a SocialAPI.ai webhook pointed at an n8n Webhook node and your workflow runs the moment a new comment, DM, mention, or review arrives. That turns n8n into a real-time social inbox automation instead of a polling job. See https://social-api.ai/blog/social-listening-webhooks.
Every endpoint returns the same field names regardless of platform, so you map data once in n8n and it works everywhere. Interaction IDs are stable and reversible, which makes multi-step workflows that read then reply straightforward to build.
Connecting each social network to n8n separately means an OAuth app and custom error handling per platform. SocialAPI.ai gives every network one credential and one node. See how it compares.
FAQ
Add a header-auth credential in n8n with your SocialAPI.ai API key as a Bearer token, then use the HTTP Request node to call any endpoint. The same credential works for reading comments and DMs and for publishing posts across every connected network.
n8n does not ship a single node that covers every social network. With SocialAPI.ai you do not need one: the built-in HTTP Request node calls one REST API that reaches Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads.
Yes. Point the HTTP Request node at the SocialAPI.ai publishing endpoint and a workflow can post to Instagram, TikTok, and the other supported networks. The same node shape works for every platform because the API normalizes them.
Create a SocialAPI.ai webhook that points at an n8n Webhook node. When a new comment, DM, mention, or review arrives, SocialAPI.ai posts the event to n8n and your workflow runs immediately, with no polling required.
Yes. SocialAPI.ai has a free tier with no credit card, and reads such as fetching comments and mentions are always free. You can connect accounts, get an instant API key, and call the API from n8n on the free plan.
