Status codes

Bloc uses standard REST status codes to indicate success or failed requests on our API.

In general, codes like 2xx indicate success; 4xx means an error based on the information provided (e.g. wrong API keys or missing customer credentials); 5xx indicates an error with our servers (and these are very rare).

Let’s clarify them further.

Status Code	Meaning
200, 201, 202	Everything is alright.
400	Bad Request. check your request body to ensure all required data is passed.
401	Unauthorized. Ensure you are passing the correct API keys.
404	Not found. The resource you are looking for does not exist.
403	Not enough permission to perform this operation
429	Too many requests are being sent in a short period of time.
500, 502, 503, 504	Definitely our fault. Rarely happens.
