Prerequisites

Before using this plugin, you need:

2. R2 buckets with the files you want to access
3. Cloudflare credentials with appropriate permissions

Configuration Steps

1. Create API token for R2 (if not already exists):

   • Sign in to the Cloudflare Dash
   • Navigate to R2 object storage
   • Click "Manage API tokens" → "Create User API token"

2. Set Permissions:

   • Provide a token name
   • Attach policies that grant R2 access:
     • Admin Read only (for read-only access to all buckets)
   • Click "Create User API token"

3. Save Access Keys:

   • Save the Access Key ID and Secret Access Key securely

4. Configure the Plugin in Dify:

   • Access Key ID: Enter the Access Key ID from your Cloudflare API token

   • Region Name: Enter your Cloudflare region (e.g., wnam, enam, weur, eeur, apac, auto)
   • Account ID: Enter your Cloudflare Account ID (you can get it from your address bar)
   • Click "Save" to store the credentials

Security Considerations

• Credentials: Store your Cloudflare credentials securely and never share them
• Permissions: Use the principle of least privilege - grant only necessary R2 permissions
• Region: Ensure you're using the correct Cloudflare region for your buckets
• Encryption: Consider using R2 server-side encryption for sensitive data

Troubleshooting

Common Issues

1. "Credentials not found" error:

   • Verify that Access Key ID and Secret Access Key are correctly configured

2. "Access Denied" error:

   • Verify the bucket policy allows access from your API token

3. "Bucket not found" error:

   • Check that the bucket name is correct
   • Ensure the bucket exists in the specified region

4. Region connectivity issues:

   • Verify the region name is correct (e.g., auto)
   • Ensure the bucket exists in the specified region
