Find out more about what common errors mean in the AudioStack API

AudioStack uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a speech call failed, etc.). Codes in the 5xx range indicate an error with AudioStack’s servers (these are rare).

403ForbiddenThe API key doesn’t have permissions to perform the request.
404Not FoundThe requested resource doesn’t exist.
409ConflictThe request conflicts with another request (perhaps due to using the same idempotent key).
