Do not get a signup email when create a customer via api

[Stakater SRE _ 1]

Hi,

I m using this JIRA service desk api endpoint to create a customer. 

https://developer.atlassian.com/cloud/jira/service-desk/rest/api-group-customer/#api-rest-servicedeskapi-customer-post

If I create the customer manually from a jira-service-desk project, the customer gets a sign up email. But if I create a customer using this api call than although a customer gets created, they don't get any signup email. Is there a way by which the customer also gets a signup email when it is created by a using the api?
