The Label Insight APIs will respond with a series of standard HTTP status codes, that will inform the caller if success or failure has happened, along with some metadata about the failure.

The standard Label Insight API response codes are defined in the table below.

Each API might have specifications about new status codes or different meanings. If these exist, they will be dictated in a HTTP Response Codes block under each endpoint!
