Outbound Call API - API Responses

API Responses

Voice2Phone Outbound Call API 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, and codes in the 5xx range indicate an error with Voice2Phone's servers (these are rare).

200 - OK Everything worked as expected.
400 - Bad Request The request was unacceptable, often due to missing a required parameter.
401 - Unauthorized No valid API key provided.
402 - Request Failed The parameters were valid but the request failed.
404 - Not Found The requested resource doesn't exist.
429 - Too Many Requests Too many requests hit the API too quickly.
500, 502, 503, 504 - Server Errors Something went wrong on Voice2Phone's end. (These are rare.)
