Share a pre-verified phone number with another business entity, granting specified permissions for collaborative WhatsApp Business messaging operations.

Use Cases:

• Enable partner businesses to use your pre-verified phone numbers for messaging
• Share phone number resources between parent and subsidiary businesses
• Facilitate multi-business WhatsApp integrations with shared phone number access
• Establish temporary or permanent phone number sharing relationships

Business Logic:

• Only businesses with appropriate ownership or sharing rights can share phone numbers
• Shared phone numbers maintain original ownership while granting usage permissions
• Multiple businesses can have access to the same phone number with different permission levels
• Sharing relationships can be time-limited with automatic expiration

Rate Limiting: Standard Graph API rate limits apply. Use appropriate retry logic with exponential backoff.

Validation:

• Pre-verified phone number must exist and be accessible to the requesting business
• Target business must be a valid and accessible business entity
• Requested permissions must be valid and within the scope of allowed sharing permissions
• Sharing operation must comply with business relationship and access control policies
