• src/index.ts:1016-1019 (handler)

  MCP tool handler for siigo_create_purchase. Extracts purchase data from args and delegates to SiigoClient.createPurchase, then formats and returns the result as text content.

  private async handleCreatePurchase(args: any) {
    const result = await this.siigoClient.createPurchase(args.purchase);
    return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }] };
  }

• src/index.ts:538-548 (schema)

  Tool schema definition including name, description, and input schema for creating a purchase.

  {
    name: 'siigo_create_purchase',
    description: 'Create a new purchase',
    inputSchema: {
      type: 'object',
      properties: {
        purchase: { type: 'object', description: 'Purchase data' },
      },
      required: ['purchase'],
    },
  },

• src/index.ts:120-121 (registration)

• src/siigo-client.ts:163-165 (helper)

  SiigoClient method that performs the actual API call to create a purchase by POSTing to /v1/purchases.

  async createPurchase(purchase: any): Promise<SiigoApiResponse<any>> {
    return this.makeRequest<any>('POST', '/v1/purchases', purchase);
  }

• src/siigo-client.ts:41-59 (helper)

  Core helper method in SiigoClient that handles authentication, makes HTTP requests to Siigo API, and processes responses/errors.

  private async makeRequest<T>(method: string, endpoint: string, data?: any, params?: any): Promise<SiigoApiResponse<T>> {
    await this.authenticate();
  
    try {
      const response: AxiosResponse<SiigoApiResponse<T>> = await this.httpClient.request({
        method,
        url: endpoint,
        data,
        params,
      });
  
      return response.data;
    } catch (error: any) {
      if (error.response?.data) {
        return error.response.data;
      }
      throw new Error(`API request failed: ${error.message}`);
    }
  }
