WhatsApp Business Platform - WhatsApp sends fail due to '131008' Error

Content Builder

• Navigate to Content Builder
• Review the content and variables within your WhatsApp Message Template
  • WhatsApp Messages can have two types of values for variables:
    • Static
    • Dynamic
      • Personalization Strings through the use of AMPscript

Please note, a common cause for this error is using the same Personalization String in multiple Variables .

For example, the Personalization String, %%FirstName%% is used in two Variables, 1 & 3, of your content.

To resolve this, you will need to use AMPscript to have 2 different Personalization Strings, such as %%FirstName%% for Variable 1 and %%FirstNameABC%% for Variable 3. Please see the How to Use AMPscript for META WhatsApp Integration in Salesforce Marketing Cloud article for more details.

Entry Source

• Navigate to your Entry Source within Contact Builder
