Hi team,

I’ve noticed an issue when creating contacts via the Chatflow API.

• When I send US phone numbers in the mobile field (e.g. 11234567890), they are correctly stored and appear in the Phone Number field of the contact profile.
• When I send Mexican numbers in the mobile field (e.g. 5216644162589 or +5216644162589), the contact is created successfully and the API response even returns the normalized value with +521..., but in the Chatflow UI the Phone Number field remains empty.

This prevents me from sending WhatsApp messages to Mexican contacts, since the Phone Number field is not being populated.

Could you please confirm what is the exact format expected for Mexican numbers in the mobile field so that they are properly recognized and saved in the Phone Number field?

Thanks in advance,
