I'm getting a bit crazy and i don't really understand this.
How should I put together the file. I got from the instructions that the authorization part should be at the top.
<?xml version="1.0" encoding="UTF-8"?>
<head>
Accept: application/xmlAccess-Token: 605de498-486c-ae9f-b740-119cd660badfClient-Secret: 2a5OUpaWhzContent-Type: application/xml
</head>
<POST>https://api.net/suppliers</POST>
<Supplier>
<Name>Taxi AB</Name>
</Supplier>
But the file just returns error from the head part.
