# API errors

Sender 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, can not send campaign, etc.). Codes in the 5xx range indicate an error with Sender servers.

# 2xx - OK Response

It may be 200 or 201 response. Everything worked as intended.

# 4xx - Bad Request

# 400 - Bad request

It means that you sent a bad request. More information will be shown in the error message.
