In our API, the from name of an email can be changed by the API user by modifying the from field in the API call. For example, to use New Product as the from name, the API user could use the following JSON body:
{
"recipient": "[email protected]",
"subject": "Hello I am testing",
"body": "Thanks for atending, Hope you are doing well.",
"from": "Nomsa <[email protected]>"
}
