How to Disable Docusign Emails from API for create envelope?

I was reading the guide found here and it talked about how we can disable Docusign from sending emails if we use clientid. However, after using Docusign create envelope api request for composite template and including the client id, the emails are still being sent when we generate the recipient signing url. Below is my JSON contract I sent

{
   "emailSubject": "Some Subject",
   "status": "sent",
   "compositeTemplates": [
      {
         "serverTemplates": [
            {
               "sequence": "1",
               "templateId": "SOME ID"
            }
         ],
         "inlineTemplates": [
            {
               "recipients": {
                  "signers": [
                     {
                        "name": "Ashwin Jacob",
                        "email": "[email protected]",
                        "recipientId": "1",
                        "clientUserId": "1",
                        "status": "sent",
                        "embeddedRecipientStartURL": "SIGN_AT_DOCUSIGN",
                        "roleName": "Advisor"
                     }
                  ],
                  "carbonCopies": null
               },
               "sequence": "1"
            }
         ]
      }
   ],
   "recipients": {
      "signers": [
         {
            "name": "Mailnator Jacob",
            "email": "[email protected]",
            "recipientId": "1",
            "clientUserId": "1",
            "status": "sent",
            "embeddedRecipientStartURL": "SIGN_AT_DOCUSIGN",
            "roleName": "Advisor"
         }
      ]
   }
}

Not sure if this is relevant but we are hardcoding the client user id to be 1 every time.

Solution

Since you are using embeddedRecipientStartURL along with clientUserId in your createenvelope call so DocuSign will send an email. Remove embeddedRecipientStartURL from your request then you will not receive any email from DocuSign. Setting clientUserId means you want to use embedded signing, for embedded signers DocuSign does not send any initial email by default but if you set embeddedRecipientStartURL in the request then you are asking DocuSign to send the initial email for embedded signers as well.
