SMS Outbound configuration

Dear experts,

I am setting up the Mashup Webservice for SMS outbound.

The web service is working fine in mashup simulation with some static data, in fact i receive sms messages.

Once i change parameters values using the placeholders mentioned in the guide, when i try to send an sms from a ticket i get HTTP error 400.

I think that is an issue related to placeholders.

These are the placeholders of the admin guide:

• [#SUBJECT[
• [PHONE_NUMBERS]
• [#MESSAGE]

If anyone of you configured successfully the SMS outbound mashup, could you please confim or tell me the correct placeholders ?

Thank you very much
