Multilingual template structure
Each WhatsApp template is linked to a specific language at creation time. To support Italian, English and Spanish, you must create three separate templates with the same name but different languages.
At sending time, choose the template in the appropriate language for the recipient. Meta requires the text of each template to be in the declared language.
Message routing by language
Language-based routing can be implemented three ways: based on number country code, based on CRM client preferences, or based on the first language used by the client in a previous conversation.
Dedicated WhatsApp numbers per market
For an optimal experience in each market, consider registering separate local numbers for each country. This increases recipient trust who sees a local sender.
Operational considerations for multilingual teams
For multilingual support teams, inbound conversation routing must automatically assign Italian conversations to Italian-speaking agents. Chat API supports this routing based on contact tags or attributes.
