api: Sears Marketplace Seller API
published: true
name: Seller Portal Sandbox
host: https://sellersandbox.sears.com
signup: https://sellersandbox.sears.com/SellerPortal/d/index.jsp
url_rule: >-
  Every production URL works in the sandbox by substituting the host - replace
  https://seller.marketplace.sears.com with https://sellersandbox.sears.com and leave the path,
  version and query parameters unchanged.
note: >-
  A full replica environment rather than a test-mode flag. There are no test key prefixes, no
  magic test identifiers and no test card numbers, because the sandbox is a separate host with its
  own separately-registered seller account and its own credentials. Nothing in this file is an
  invented test value; the only concrete value the provider publishes is the instruction that a
  fake 16-digit card number is acceptable during sandbox registration, and no such number is
  reproduced here.
test_vs_live:
  mechanism: separate host and separate account, not a key prefix or a mode flag
  key_prefixes: []
  data_isolation: >-
    The sandbox is a blank slate for security reasons - no items, orders or settings are copied
    from the production account. Sellers must build their own items, inventory and orders before
    testing.
access:
  self_service: false
  gated: true
  steps:
    - Self-register at https://sellersandbox.sears.com/SellerPortal/d/index.jsp using the "Sign up" button
    - Use the same email address and the same FEIN or SSN as the production Sears Marketplace account
    - Valid card and bank details are not required, but a 16-digit placeholder card number must be supplied
    - Activate the account from the "Sears Marketplace Account Authentication Required - Sandbox" email
    - Complete the account setup workflow and submit for approval
    - Open a support request at https://marketplace.sears.com/support with topic Accounts, subtopic "Sandbox Activation Request", quoting the production seller ID and the sandbox seller ID
    - Wait for the "Sears Marketplace - Your account is activated - Sandbox" email
  note: >-
    The final manual step is load-bearing. The provider states that without the support request the
    sandbox account may never be activated.

      The only way to create test orders. There is no UI mechanism to generate a sample purchase
      order; it must be done through this API. Up to five comma-separated external item ids may be
      supplied and one order line is created per id.

  status: 503
  note: >-
    The sandbox host answered 503 to an anonymous schema request on the day of this harvest, and
    403 to every /.well-known/ probe. The production host served the equivalent schema with a 200,
    so the schemas in xsd/ were taken from production. The 503 is recorded as observed, not
    interpreted as an outage claim.
