What field contains the message ID in SMPP?

In the submit_sm_resp command, the message_id will be returned in the field message_id .

 In the deliver_sm request, it depends on the SMPP version used, but in general for both 3.3 and 3.4, we send it back on the short_message field.

 If you only support version 3.4 and need to receive it on a separate TLV (0x001e) then please let us know ( email support@nexmo.com) as we would need to configure this for your account.
