Channel: Zernio

Zernio is a unified social-media DM platform that covers Instagram, Facebook, X (Twitter), and others through a single API. Connect once and your agent handles DMs across all linked social accounts.

Before you start

1. Sign up at zernio.com and enable the Inbox addon on your account.
2. Connect your social accounts (Instagram, Facebook page, X, etc.) in the Zernio dashboard.
3. Go to Settings → API and create an API key.
4. In the Zernio dashboard configure a webhook, subscribe to message.received and comment.received, and set a webhook secret.

Example prompts

Connect the social-agent to Zernio.

Add Instagram and Facebook DMs to my marketing agent via Zernio.

What happens

1. The widget asks for credentials:

   name	type
   SOCIAL_AGENT_ZERNIO_API_KEY	password
   SOCIAL_AGENT_ZERNIO_WEBHOOK_SECRET	password

2. Shmastra wires the adapter:

   import { Agent } from '@mastra/core/agent'
   import { createZernioAdapter } from '@zernio/chat-sdk-adapter'
   import { createAgentChannels } from '../shmastra'
   
   export const socialAgent = new Agent({
     id: 'social-agent',
     channels: createAgentChannels({
       adapters: {
         zernio: createZernioAdapter(),
       },
     }),
   })

3. The widget prints the webhook URL to paste into the Zernio dashboard:

   {PUBLIC_URL}/api/agents/social-agent/channels/zernio/webhook

4. Send a DM to any connected social account — the agent replies.

Tips

• Multiple platforms, one agent — all social DMs from all connected accounts arrive in the same agent thread. Use message.platform in your agent's context if you need to branch on which network sent the message.
• Comments vs DMs — subscribe to comment.received if you also want the agent to reply to comments on posts, not just direct messages.
