Hey there, I wanted to ask if it is possible to create contacts externally, not within the Odoo space.

An example would be:

1. Customer registers for my site (hosted separately from Odoo)

2. My server calls an API on Odoo side to create the contact with relevant fields

Also, wanted to ask if its possible to send the dynamic email content through the API as well. Am abit confused about the entire Odoo ecosystem.
