Broker APIs with error codes decoded here
An error code is what an API sends back when it refuses a request. A decoded error page on this site gives what the code means, the usual cause and the source it was read on.
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.
Not recorded means this site holds no record. It does not mean the broker or platform lacks it. Rows are in name order, the order is not a ranking, and nothing here recommends a broker.
How each row is decided
Yes means this site publishes at least one error record for it, and the count is of those records. Not recorded means this site has decoded none yet. It says nothing about which errors the API can return.
- Yes
- A record on this site says so: a structured field, a record that exists, or a sentence in a record that was read and entered in the capability facts register, with the reason printed beside it. 14 of the 29 rows below.
- Not recorded
- This site holds no yes or no for it. That is a gap in this dataset. It is not a statement that the broker or platform lacks the capability. 15 of the 29 rows below.
