# Posting Content in Channels

>  

Only users who follow channels can create posts within them. Channel posts support rich markdown content, including formatting, images, and embedded links.

**React Hook Example for Posting Content in Channels**:

```typescript theme={null}
import { usePost } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function PostToChannel({ channelId, ownedUserId }) {
  const { postToChannel } = usePost();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handlePost() {
    const result = await postToChannel({
      amounts: [0, 0],                           // Required, typically [0, 0]
      appId: 'your-app-id',                      // Explicitly required application ID
      network: 'testnet',                        // Required network ('testnet' or 'mainnet')
      channelId,                                 // Channel ID where post is created
      data: 'Sui offers significantly higher transaction throughput...', // Main markdown content
      description: 'Performance and scalability comparison',             // Markdown summary
      title: 'Understanding Sui vs Ethereum',    // Post title in markdown
      ownedUserId,                               // Poster’s owned user ID
      self: account.address                      // Poster’s wallet address
    });

    if (result.ok) {
      await signAndExecuteTransaction({ transaction: result.transaction });
      console.log("Posted to channel successfully!");
    } else {
      console.error("Error posting to channel:", result.err);
    }
  }

  return <button onClick={handlePost}>Post Content</button>;
}

export default PostToChannel;
```
