What type of values are expected for specific attributes in metafields ?

Different attributes require different format. If your values do not follow a certain expected format, the data might not be pushed to GMC.



While creating metafields, it is important to know their type and format. This will help you push information to GMC without any errors. Please note that the format is case sensitive and refer to the respective attribute documentation if more information is required.
