Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/flash-express: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The FlashExpress Open API is the merchant-facing integration surface for Flash Express parcel logistics in
    Thailand. All calls are HTTPS POST with an application/x-www-form-urlencoded body and a JSON response envelope of code/message/data.
    Every request is authenticated with a merchant id (mchId), a random nonce string (nonceStr) and an uppercase SHA256 signature
    (sign) computed over the ASCII-sorted non-empty parameters joined with a merchant secret key issued by Flash Express support.
    The API covers warehouse listing, the Flash standard address/location tree, sub-account creation, order creation (including
    creation against a merchant-supplied tracking number), order modification and cancellation, single and batch parcel route
    tracking, delivered-proof retrieval, 100x180mm and 100x75mm label pre-print, freight-rate estimation, courier pickup notification
    scheduling and cancellation, and webhook subscription management.
