Hello,

Can anyone send me the sample code to send an email using groovy script. I have gone through some restapi files but didn't get the output.

This is the code that i'm trying , no idea where i'm wrong.

Please suggest any idea on this and thanks in Advance

Code:

def sendEmail(connectionName,emailTo,emailSubject,emailBody,emailAttachments) {

	HttpResponse<String> jsonResponse = operation.application.getConnection("EPBCS_TEST")

	.post("/interop/rest/v1/services/sendmail")

	.header("Content-Type", "application/x-www-form-urlencoded")

	.queryParam("to", 'abc@gmail.com')

	.queryParam("subject", 'Test email')

	.queryParam("body", 'emailBody')  

	.asString();

    println(jsonResponse.body)

}
