Invalid request

HTTP 400   invalid_request

What it means

The request is malformed: the JSON doesn't parse, a field is missing, unknown or of the wrong type, an amount has more than 2 decimal places, or a memo is over 150 characters. A misspelt field is an error, not an omitted one.

What to do

Read errors in the response: it maps each bad field to its problems. Fix the request and send it again with a new timestamp.
