Errors

Assembly follows conventional HTTP response codes to indicate the success or failure of an API request and uses the following codes:

Error Code Meaning
200 OK — Everything worked as expected.
400 Bad Request — The request was unacceptable, typically due to an invalid or missing parameter.
401 Unauthorized — No valid API key provided.
404 Not Found — The requested resource doesn't exist.
429 Too Many Requests — Too many requests hit the API too quickly.
500 Internal Server Error — There was an error with Assembly's servers. Try again later or contact Assembly support.
