Wildberries API TypeScript SDK / BaseClient

Class: BaseClient

Defined in: client/base-client.ts:81

Base HTTP client for all Wildberries API modules

This class provides a unified HTTP interface with:

• Automatic authentication header injection
• Configurable timeouts
• Typed error transformation
• Debug logging with PII sanitization

All API modules receive a BaseClient instance via dependency injection to ensure consistent behavior across the SDK.

Examples

const config: SDKConfig = {
  apiKey: 'your-api-key',
  timeout: 30000,
  logLevel: 'debug'
};

const client = new BaseClient(config);

// Make GET request
const data = await client.get<ProductResponse>(
  'https://content-api.wildberries.ru/api/v1/products'
);

const data = await client.post<CreateProductResponse>(
  'https://content-api.wildberries.ru/api/v1/products',
  { brandName: 'MyBrand', title: 'Product Title' },
  { headers: { 'X-Request-ID': '123' } }
);
