Website credentials

Best Practices

Most things return 2xx or 5xx
In-API status:
Success [Great!]
RegistrationError [Retry won't help]
RequestError [Probably asking for the wrong thing]
SystemError [Retry very well may succeed]
plz with exponential backoff

Best practices (cont'd)

Still over the public web
..so use low-integerial # of retries
Circuit Breaker pattern!
SSL/TLS, if desired
Cache results for frequent requests or ref data queries

Fabulous prizes
