CarrierType

The CarrierType object provides an interface for determining the valid fields of a CarrierAccount. The list of CarrierType objects only changes when a new carrier is added to EasyPost.

The CarrierType objects consist of their top level attributes as well as a Fields object that contains credentials and sometimes test_credentials sub-objects, which themselves are collections of attributes for CarrierAccounts creation, as well as metadata about presentation and the naming of said attributes.

There are a couple special case CarrierAccounts, with structures differing somewhat from the norm. For instance, instead of credentials for a "UspsAccount", it has only auto_link: true, which indicates that it is an account that can be added or removed without any carrier-specific fields.

CarrierType Object
{
  "object": "CarrierType",
  "type": "AmazonMwsAccount",
  "readable": "Amazon MWS",
  "logo": null,
  "fields": {
    "credentials": {
      "access_key_id": {
        "visibility": "visible",
        "label": "AWS Access Key ID"
      },
      "secret_key": {
        "visibility": "password",
        "label": "Secret Key"
      },
      "merchant_id": {
        "visibility": "visible",
        "label": "Seller ID"
      }
    }
  }
}

Fields object

auto_link
boolean
If this key is present with the value of true, no other attributes are needed for CarrierAccount creation.
custom_workflow
boolean
If this key is present with the value of true, CarrierAccount creation of this type requires extra work not handled by the CarrierAccount standard API.
credentials
If this object is present, required attribute names and their metadata are presented inside.
test_credentials
If this object is present, it contains attribute names and metadata just as the credentials object. It is not required for CarrierAccount creation if you do not plan on using the CarrierAccount for test mode.
Fields Object
{
  "credentials": {
    "access_key_id": {
      "visibility": "visible",
      "label": "AWS Access Key ID"
    },
    "secret_key": {
      "visibility": "password",
      "label": "Secret Key"
    },
    "merchant_id": {
      "visibility": "visible",
      "label": "Seller ID"
    }
  }
}

Credentials object

name
string
The key for each attribute sub-object within credentials is the name of the attribute for submission on CarrierAccounts
visibility
string

There are five possible values, which encode the security need and storage type for each attribute:

  • visible
  • checkbox
  • fake
  • password
  • masked
label
string
Most attributes have generic names, so for clarity, a "label" value is provided for clearer representation when rendering forms.
Credentials Object
{
  "access_key_id": {
    "visibility": "visible",
    "label": "AWS Access Key ID"
  },
  "secret_key": {
    "visibility": "password",
    "label": "Secret Key"
  },
  "merchant_id": {
    "visibility": "visible",
    "label": "Seller ID"
  }
}
