aws emails with api gateway ses and lambdas

I need to send templated emails with AWS SES
For this I plan to create AWS API Gateway witch will take as params next
{
"Subject":"Lead Created",
"Text":"AWS API Gateway - Lambda SES",
"To":"email1, email2",
"Themeplate":"ThemeplateName",
"Params":"email params"
}

Then we will use Node js Lambda to call SES

To deploy I plan to use serverless framework
