Complete integration guide for ${partner_type} partners.
## Quick Start
1. **Authentication Setup**: Use \`payware_generate_code_example\` with \`operation="authentication"\`
2. **Environment Config**: Set up .env file with credentials
3. **API Integration**: Use operation-specific examples
4. **Testing**: Start with sandbox mode
## Implementation Overview
- **Languages**: ${stats.languages} supported (${advancedCodeGenerator.supportedLanguages.join(', ')})
- **Frameworks**: ${stats.frameworks} supported
- **Operations**: ${stats.totalOperations} available operations
- **Coverage**: ${stats.coverage}% complete implementation
## Available Operations
${Object.entries(availableOps)
.map(([category, ops]) => `### ${category.charAt(0).toUpperCase() + category.slice(1)}\n${ops.map(op => `- \`${op}\``).join('\n')}`)
.join('\n\n')}
## Code Generation Examples
\`\`\`javascript
// Basic transaction
payware_generate_code_example({
operation: "create_transaction",
language: "${language}",
partner_type: "${partner_type}"
})
// Framework-specific
payware_generate_code_example({
operation: "create_transaction",
language: "${language}",
framework: "django", // or express, laravel, etc.
partner_type: "${partner_type}"
})
// Transaction creation
payware_generate_code_example({
operation: "create_transaction",
language: "${language}",
partner_type: "${partner_type}"
})
\`\`\`
## Framework Support for ${language}
${advancedCodeGenerator.supportedFrameworks
.filter(f => {
if (language === 'python') return ['django', 'fastapi', 'flask'].includes(f);
if (language === 'nodejs') return ['express', 'nestjs', 'koa'].includes(f);
if (language === 'php') return ['laravel', 'symfony'].includes(f);
if (language === 'java') return ['spring', 'springboot'].includes(f);
if (language === 'csharp') return ['aspnet', 'blazor'].includes(f);

if (language === 'ruby') return ['rails', 'sinatra'].includes(f);
return false;
})
.map(f => `- **${f}**: Framework-specific implementations available`)
.join('\n') || '- Standard implementations available'}
## Best Practices
1. **Security**: Always use sandbox mode for testing
2. **Authentication**: Implement proper JWT token handling
3. **Error Handling**: Include comprehensive error handling
4. **Testing**: Use the \`include_tests: true\` option for unit tests
5. **Monitoring**: Implement proper logging and monitoring
## Support
For specific implementations, use the code generation tool with your exact requirements:
\`\`\`
payware_generate_code_example(operation, language, partner_type, options)
\`\`\`
All ${stats.totalOperations} operations are fully implemented across all ${stats.languages} supported languages.
