Can the WhatsApp Business Calling API lead to a WABA ban?

Yes, indirectly. While calling itself doesn't cause a ban, how you use the feature directly impacts your Quality Score and adherence to the WhatsApp Business Policy, which can lead to restrictions or a permanent ban.

Risk Factors Leading to a Ban:

• Violating Consent (High Risk): Placing Business-Initiated Calls without the customer's explicit, opt-in permission is a direct violation of Meta's policy.
• High Negative Feedback: If users frequently report or block your business after receiving a call, this significantly lowers your Quality Score. Low Quality Scores can lead to:
  • Tier restrictions (e.g., lower messaging limits).
  • Temporary access revocation (e.g., restricted access to the Calling API).
  • Permanent WABA ban for sustained low quality.
• Abuse and Harassment: Using the calling feature for unsolicited, deceptive, or harassing communication will be considered a severe violation of the Commerce and Business Policies, leading to an immediate ban.
• Unanswered Calls: If your business places four consecutive Business-Initiated Calls that go unanswered, the customer's call permission is automatically revoked by the system. While not a ban, this restricts your ability to use the feature.

The most crucial rule: Always respect user choice, secure explicit consent before calling, and closely monitor your WABA's Quality Score in the Meta Business Manager.
