Error handling

Passport APIs will use standard HTTP status codes to reflect the appropriate result of the request. The set of codes we leverage are outlined below. When a failure occurs, the API may respond with additional details in the response body. The format of this detail will follow the standard defined by RFC 7807 which outlines a standard model for describing “Problem Details for HTTP APIs.” Passport defines it’s use of RFC 7807 with the following specifics:

• Problem detail “Types” are a URN that provide a descriptive, human readable error code that is prefixed with the namespace: “io.passportlabs:error:”
• Problem types that are specific to each API will be documented as part of that API
• If additional detail is included as part of the problem detail, those custom fields will be wrapped in an element that is titled “additional_details”

An example is provided below:

{
    "type": “io.passportlabs:error:zone_not_found",
    "title": "Zone not found ",
    "detail": "The zone named 501 was not found",
    “additional_details”: {
   	 "zone_id": 501
    }  
}

HTTP status codes

The following HTTP status codes may be leveraged by Passport APIs to convey the appropriate result of a request. Not all APIs will support all of the codes listed below. What codes may occur will be included in the documentation for each API.
