Considerations for WhatsApp Unified Messaging

Review these important considerations before setting up WhatsApp Unified Messaging.

• Unified Messaging is supported in a sandbox that's created after May 9, 2025.
  • Meta doesn't support business-to-business messaging.
• We don't support associating a single WABA with more than one Salesforce org. For optimal performance, don't reuse a WABA across multiple Salesforce orgs. A sandbox and a production org are considered two separate orgs.
  • Due to Meta's rules and regulations, some messages that you send might not be delivered to your customers. For example, a message isn't delivered if the customer blocked your phone number, hasn't been online for 30 days, or is in a restricted or sanctioned country. In certain situations, Meta doesn't disclose the reason for non-delivery due to privacy and policy reasons. For more information and potential workarounds, see WhatsApp Cloud API Support.
• Salesforce ensures system integrity by moving messages that cannot be processed after maximum retry attempts to a secure Dead Letter Queue (DLQ) for manual intervention and root-cause analysis. To maintain conversational relevance and performance, any message exceeding a 24-hour processing window will be automatically expired and purged from the queue.
