@MTS_Ciaran That's odd. Yes, I am using command curl in Linux exactly as I posted in the previous post. As you were suggesting, I tried a different account. I created a new account with US as an origin and it worked! So I created another account in Czech (which I need because of our clients) and it didn't work again. I got stuck with the previous error. TIMESTAMP=2017-07-04T12:50:41Z
CORRELATIONID=294ed0bd7d3cb
ACK=Failure
VERSION=51.0
BUILD=33063964
L_ERRORCODE0=11945
L_SHORTMESSAGE0=Invalid Data
L_LONGMESSAGE0=The button country and language code combination specified is invalid.
L_SEVERITYCODE0=Error So obviously, this is related to that the account resides in Czech. Unfortunately, as it is "must have", what can I do with that? Do you have any thoughts, please?
