Tutorial: Building a Scalable WhatsApp Business Account Verification Pipeline

Описание и применение

Автоматизированный процесс проверки тысяч номеров на наличие аккаунтов WhatsApp Business с помощью асинхронного API Checknumber.ai, позволяющий сегментировать контакты в CRM.

Задача

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

Результат

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.

Рабочий процесс

• 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.

Доказательства

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

Источник

Continue polling until the status transitions to exported.
