Tutorial: Building a Scalable WhatsApp Business Account Verification Pipeline

说明与用途

使用 Checknumber.ai 的异步 API 自动验证数千个电话号码是否为 WhatsApp Business 账户，帮助 CRM 进行受众细分。

问题

Large CRM databases need to identify which contacts use WhatsApp Business accounts, but manual verification of thousands of numbers is impractical.

结果

The workflow enables automated verification of thousands of phone numbers for WhatsApp Business registration, producing a structured result file that can be directly imported into a CRM for targeted communication.

工作流

• Submit a batch file of E.164 phone numbers to the /v1/tasks endpoint with task_type="ws_business" and receive a task_id.
• Poll the /v1/gettasks endpoint using the task_id until the status becomes "exported"; avoid aggressive polling intervals.
• Download the result file from the provided result_url; the file contains columns: number, whatsapp, business.
• Import the result file into the CRM, preserving original column names for data integrity.
• Handle edge cases by checking API response codes (e.g., 503, 400) and implementing retry logic with appropriate delays.

证据

The API uses an asynchronous pattern. You submit a file, receive a task_id, and poll for completion.

Continue polling until the status transitions to exported.
