OAuth 2.0 error codes explained
8 entries decoded. These are the error codes an OAuth 2.0 server returns when a token request or a call with a token is refused. Each page says what the entry means, what it means in trading API work and what to do next, and links to the place it is defined: RFC 6749, The OAuth 2.0 Authorization Framework.
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.
