Start with the connection type and message history when a WhatsApp notification does not reach a client. Different connections have different failure causes.
Steps
Check the client number and country code.
Open Integration and confirm the intended WhatsApp connector is enabled.
For WhatsApp Web, check the connection status. For a provider, check its credentials and account status.
Check the relevant notification and client-specific notification settings.
For API messages, review the approved template and variable mapping.
Open Setup → Message History and inspect the delivery information for the message.
How do I check the result?
Verify one message before resending in bulk. Check that the client did not receive a duplicate.
If it does not work
If delivery still fails, send Support the message type, time, connector and error shown in history. A saved template is not proof of delivery.
Illustrated guide
WhatsApp Integration is the configurable API connection. Use the provider instructions for its fields.
WhatsApp Web is the QR/session connection from your own number.
Provider cards such as Twilio, Interakt, Zoko and Botat have separate setup screens; scroll for the other providers.
Open Integration, identify the active connection and troubleshoot that provider before changing templates or reconnecting.
