@sam9116 Thank you for trying to figure this out. I still got a 400 error with that ominous note, but the note itself is also present in the response received...

@sam9116 I see, would you mind sharing which cookies (other than sp_dc ) you are using, if any? I added an user agent, too - but still get a 400....

Thanks, I got it working too :)
