    Enhancements derived by API Evangelist from the verbatim Swagger 2.0 document
    fetched at https://api.moreflo.com/swagger/docs/v2 on 2026-08-26. The harvested
    document is never mutated; every addition below is ours, not Northmill's.

    update:
      x-apievangelist-slug: northmill
      x-apievangelist-api: Northmill Flo API
      x-provider: Northmill Bank AB
      x-provider-note: >-
        Served from api.moreflo.com. MoreFlo was acquired and rebranded as Northmill
        Flo; moreflo.com and api.moreflo.com both 30x to www.northmill.com, and the
        Swagger UI at api.moreflo.com/swagger/ui/index is titled "Flo API".

      x-sandbox: https://test.api.moreflo.com
      x-legal-entity: Northmill Bank AB (org.nr 556709-4866)

    update:
      x-apievangelist-conventions:
        store_scoping: >-
          Every collection is published twice - /v2/<resource> and
          /v2/stores/{externalStoreId}/<resource>. externalStoreId is also accepted as a
          query parameter on the unscoped form.
        pagination:
          params: [page, pageSize]
          response_fields: [list, Page, Total, PageSize, ExtraInformation]
          caveat: Total is the number of PAGES, not the number of items.
        idempotency:
          mechanism: UpdateOnExisting body flag keyed on a client-supplied natural key
          keys: [ExternalReference, ArticleNumber, CustomerNumber]
          header: none
        incremental_sync:
          params: [updatedSince, modifiedSince, createdSince, createdAfterUTC, startTimeSince, ArticleInfoUpdatedSince, QuantityUpdatedSince]
        in_band_errors:
          fields: [Success, ExtraInformation]
          warning: >-
            HTTP 200 does not mean success. Every *Result envelope carries Success and
            ExtraInformation; check both.
      x-apievangelist-gaps:
        - No 4xx or 5xx response is documented on any of the 199 operations.
        - No rate-limit headers, no 429, no Retry-After.
        - No request-id / correlation-id header.
        - No deprecation or sunset policy; v2 and v3 orders coexist with no stated migration path.
        - Contract is Swagger 2.0, not OpenAPI 3.x.
      x-apievangelist-artifacts:
        conventions: conventions/northmill-conventions.yml
        data_model: data-model/northmill-data-model.yml
        errors: errors/northmill-problem-types.yml

    update:
      x-credential-source: https://apps.moreflo.com/
      x-self-service: false
      x-note: >-
        Credentials are issued from the Flo back office; there is no self-service key
        creation and no separate test-key prefix. Environments are separated by host
        (api.moreflo.com vs test.api.moreflo.com).
