What does 415 Unsupported Media Type mean in HTTP?
The server refuses the request because its content is in a format that this method on this resource does not support. The fault may lie in the Content-Type, the Content-Encoding or the data itself.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

What should I do about 415 Unsupported Media Type?
