3. Go to Network tab
4. Send any message
5. Find Authorization header in API requests
6. Copy the token (usually starts with MTAxxxxx...)

⚠️ Important: Never share your user token!

Getting Midjourney Channel ID

1. Enable Developer Mode in Discord
   • Settings → Advanced → Developer Mode ON
2. Right-click on Midjourney channel
3. Select "Copy ID"

🎯 Usage

Basic Usage

from python_midjourney import MidjourneyClient

# Create client (automatically uses environment variables)
client = MidjourneyClient()

# Generate image
result = client.generate_image("a beautiful sunset over mountains")

if result['success']:
    print(f"Original file: {result['original_file']}")
    print(f"Split files: {len(result['split_files'])} files")
    for i, file in enumerate(result['split_files'], 1):
        print(f"  {i}. {file}")

Direct Token Specification

from python_midjourney import MidjourneyClient

# Specify token and channel ID directly
client = MidjourneyClient(
    user_token="your_discord_token",
    channel_id="your_channel_id",
    auto_split=True  # Enable auto-split
)

result = client.generate_image("cyberpunk city landscape")

Batch Processing

from python_midjourney import MidjourneyClient

client = MidjourneyClient()

prompts = [
    "cozy coffee shop with warm lighting",
    "modern minimalist workspace",
    "serene mountain lake at dawn"
]

# Batch generation (5 second intervals)
results = client.generate_batch(prompts, delay=5)

# Check results
for i, result in enumerate(results):
    if result and result['success']:
        print(f"✅ Image {i+1}: {result['total_files']} files generated")
    else:
        print(f"❌ Image {i+1}: Failed")

Quick Usage (Convenience Function)

from python_midjourney import quick_generate

# Generate image in one line
result = quick_generate(
    "fantasy castle in the clouds",
    user_token="your_token",  # Optional
    channel_id="your_channel", # Optional
    auto_split=True
)

Disable Auto-Split

from python_midjourney import MidjourneyClient

# Save original image only (no splitting)
client = MidjourneyClient(auto_split=False)
result = client.generate_image("abstract art")

print(f"Original only saved: {result['original_file']}")
# split_files will be an empty list

Check Channel Information

from python_midjourney import MidjourneyClient

client = MidjourneyClient()

# Get current channel information
info = client.get_channel_info()
print(f"Channel name: {info['name']}")
print(f"Server ID: {info['guild_id']}")

# Change to another channel
client.set_channel("another_channel_id")

⚠️ Important Notes

1. Discord Terms Compliance

• Using user tokens may violate Discord's Terms of Service
• Use only for personal projects
• Commercial use prohibited

2. Token Security

• Never share your user token
• Don't upload tokens to public repositories like GitHub
• Use environment variables or .env files

3. Usage Limitations

• Requires paid Midjourney subscription
• Must comply with Discord API rate limits
• Avoid excessive requests

4. Technical Limitations

• Internet connection required
• Dependent on Discord server status
• Dependent on Midjourney bot status

🔧 Troubleshooting

Common Errors

1. "Discord User Token not set"

# Check environment variable
echo $DISCORD_USER_TOKEN

# Set environment variable
export DISCORD_USER_TOKEN="your_token_here"

2. "Midjourney Channel ID not set"

# Set channel ID
export MIDJOURNEY_CHANNEL_ID="your_channel_id_here"

3. "Failed to get channel info: 403"

• Token is incorrect or expired
• No access permission to the channel
• Need to check Discord account status

4. "Timeout: No response from Midjourney"

• Midjourney bot is offline or response delayed
• Try increasing timeout value (default: 60 seconds)
• Check network connection

Debugging Tips

from python_midjourney import MidjourneyClient

# Debug with detailed output
client = MidjourneyClient()

# Check channel connection
try:
    info = client.get_channel_info()
    print("✅ Channel connection successful:", info['name'])
except Exception as e:
    print("❌ Channel connection failed:", e)

# Test image generation
result = client.generate_image("test image", timeout=120)
if result:
    print("✅ Image generation successful")
else:
    print("❌ Image generation failed")
