What does invalid_request mean in OAuth 2.0?
The request to the token endpoint is malformed: it is missing a required parameter, includes an unsupported parameter value other than the grant type, repeats a parameter, includes more than one credential or uses more than one way of authenticating the client. The authorisation server answers with HTTP 400 unless stated otherwise.
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 it means in trading API work
You meet it while obtaining or refreshing a token for a trading API that uses OAuth 2.0. The request for the token is wrongly built, so no token is issued.
This part is this site's own explanation, written for people learning to call a trading API. It is not part of the source cited above and it describes no particular broker.
What should I do about invalid_request?
Compare the token request with the API's documentation, parameter by parameter: the names, the spelling, the content type of the body, and that each parameter appears once.
This page is an independent explanation in plain words. The definition itself is in the source it was read from, which is the authority if the two ever differ.
