Hello,

in my case SMS provider requires following SOAP message:

<urn:MT_SendSMSListRequest>
<SenderCode>Cusromer Name</SenderCode>
<SMSList>
<SMS>
<ExternalID>1be3ed54340c48e5a20ec553353491e4</ExternalID>
<PhoneNumber>xxxxxxxx</PhoneNumber>
<Message>Message contents</Message>
</SMS>
</SMSList>
</urn:MT_SendSMSListRequest>

Any idea how to ensure each message would contain unique <ExternalID>, possibly of UUID format?

Regards, Dariusz
