How do I test my WhatsApp Business integration?

The sandbox integration allows you to send test messages from the temporary demo WhatsApp number which we’ll provide you with, or from your verified WhatsApp Business number in your account. Test messages to your pre-registered test phone numbers are free of charge and you can start testing immediately once we’ve received your application.

Steps to send a test WhatsApp messaging from the sandbox integration

Ensure that you understand the requirements around different WhatsApp message types. Test messages also need to comply with the rules created by WhatsApp for different WhatsApp message types.

You also need to ensure that you have set up at least one test phone number.

To test a reply to a customer-initiated message, send a WhatsApp message from your test phone number to your approved WhatsApp Business number and reply to the message within 24 hours. Your reply can be an unstructured conversational message if you reply within 24 hours. If you reply outside of the 24-hour window, you'll need to make use of a pre-approved template message which is available in your Clickatell account.

To test a business-initiated message or a re-engagement message (replying to an incoming message after 24 hours), you’ll also need to make use of templated messages. We have loaded some pre-approved Clickatell template messages in your account which you can use for testing purposes.

The production integration allows you to send messages from your approved WhatsApp Business number to any WhatsApp-enabled phone number.

Steps to send a WhatsApp message from your production integration

To reply to a customer-initiated message, send a WhatsApp message from any WhatsApp-enabled phone number, to your WhatsApp business number. Reply to the message within 24 hours. If you reply after 24 hours, you’ll have to make use of a template message.

To send a business-initiated message or a re-engagement message (replying to an incoming message after 24 hours), you’ll need to use an approved template message. Read more about how to submit your WhatsApp message template for approval.
