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 does HTTP 400 mean on the eToro API?

Validation failed on the request as sent, for example a missing or malformed minDate or too many instrument IDs in one call.

## How do I fix HTTP 400?

Check the required parameters for that endpoint, the date format and the number of IDs you passed, then send the corrected request once.

The checked date on this page was carried forward from an earlier reading. The source has not been reopened since.
