Microsoft Translator Php Sdk Laravel Package

Getting Started

composer require potsky/microsoft-translator-php-sdk
composer show potsky/microsoft-translator-php-sdk   # confirm the version you actually got

Look at src/ before anything else. The package is a thin wrapper — realistically one client class plus a small auth/HTTP helper — and the README from 2016 is not a reliable description of what the code does today. Two things you need to confirm in the source within the first five minutes:

1. Which API it targets. A 2016 release almost certainly authenticates against datamarket.accesscontrol.windows.net/v2/OAuth2-13 with a client ID + client secret (the old Microsoft Translator v2 / Azure DataMarket flow). That endpoint was retired. If that's what's in the source, the package cannot work unmodified and your first task is swapping auth + base URL, not writing features.
2. The HTTP layer. If it news up cURL or Guzzle internally with no injection point, you cannot mock it in tests and you cannot point it at a different host without editing vendor code.

Credentials. Modern path: create a Translator resource in the Azure portal and note the key, region (e.g. westeurope), and endpoint (https://api.cognitive.microsofttranslator.com). The current v3 API authenticates with an Ocp-Apim-Subscription-Key header — no token dance required.

First use case. Pick the narrowest one: translate a single string and dump the result from php artisan tinker. Don't start with model translation, batching, or a UI. Confirm the request is accepted, then confirm the response shape ([0]['translations'][0]['text'] in v3, a bare string in v2) — the parsing differs and that difference will shape everything downstream.

Implementation Patterns

Bind it once, configure from env. A singleton in a service provider backed by config/translator.php reading TRANSLATOR_KEY, TRANSLATOR_REGION, TRANSLATOR_ENDPOINT keeps credentials out of the codebase and gives you one place to swap client implementations.

$this->app->singleton(Translator::class, fn () => new Translator(
    config('translator.key'),
    config('translator.region'),
    config('translator.endpoint'),
));

Never call it inline in a request. Translation is a 200–800 ms network hop against a rate-limited third party. Put it behind a queued job (TranslateModel, ShouldQueue, $tries = 3, backoff() with growing delays) and translate on save via an observer. The request returns immediately; the translation lands when it lands.

Cache aggressively, keyed on the input. Translations are effectively deterministic for a given (text, from, to, textType). Cache::remember('tr:'.sha1($text.$from.$to.$html), now()->addMonth(), fn () => ...) will typically eliminate the majority of your API calls on a site with repeated strings — nav labels, product categories, boilerplate.

Batch, and chunk. Both API generations offer an array endpoint (v2 TranslateArray, v3 POST /translate with a JSON array of {"Text": ...} objects). One batched call for 50 strings is 50× cheaper in latency and rate-limit budget than 50 calls. Chunk to the documented per-request cap (v2 ≈ 10,000 characters total; v3 ≈ 50,000 characters / 1,000 elements) and split on sentence or paragraph boundaries, never mid-word.

Wrap it in your own interface. Define App\Contracts\Translator with translate(string $text, string $to, ?string $from = null): string and translateMany(array $texts, ...): array, and have the SDK sit behind an adapter. You get a swappable implementation, a fake for tests, and insulation from the package being abandoned — which, at 17 stars and a 2016 last release, it effectively is.

Fall back loudly. On failure return the source string, log the exception with the HTTP status and response body, and increment a counter. A product page rendering English in the French locale is a degraded experience; a 500 is an outage.

Multi-tenant. If different customers have their own Translator keys, don't share the singleton — resolve a fresh client per tenant from a factory and key your cache by tenant, or one customer's quota gets spent on another's traffic.

Testing. Bind a fake Translator implementation in the container and assert your job called it with the right arguments. If you must exercise the real client, point it at a fixture-backed Guzzle MockHandler; do not let CI touch the network.

Gotchas and Tips

• The auth endpoint is dead. datamarket.accesscontrol.windows.net was decommissioned; client-ID/secret OAuth against it returns 401/404 regardless of whether your credentials are valid. If the package is hardcoded to it, fork it or bypass its auth entirely and inject a Guzzle client configured with the Ocp-Apim-Subscription-Key header against api.cognitive.microsofttranslator.com/translate?api-version=3.0.
• Token lifetime (if you're on the old flow). DataMarket tokens expired after 10 minutes. If the client fetches a token per method call, you're burning two round trips per translation — cache and reuse it yourself.
• Composer conflicts. A 2016 package likely constrains Guzzle to ^5.0|^6.0. Laravel 9+ ships Guzzle 7. Check composer why-not before you fight the resolver; a 60-line Guzzle client of your own is often less work than forcing the dependency tree.
• Language codes are BCP-47, not ISO 639-1. pt-br, zh-Hans, sr-Latn — not pt, zh, sr. This is the single most common source of "the API returned garbage" or a 400.
• textType=html matters. If you're translating CMS content containing tags, omit it and the API will happily translate your attribute values and mangle markup. Set it explicitly; you can't infer it after the fact, so carry a flag on the field.
• Quota is counted in characters of input, including markup. The free F0 tier is ~2M characters/month. HTML-heavy pages burn through it far faster than you expect — measure before you turn it on for every model save.
• 429 means back off, not retry immediately. The API returns Retry-After alongside 429/503. Honour it in your job's backoff(); a tight retry loop against a rate limit gets you throttled harder.
• Pass from whenever you know it. Omitting it triggers auto-detection — an extra cost and an extra failure mode, and it will occasionally misidentify short strings ("Gift" is German as often as English).
• Empty and null inputs. Guard before calling. Behaviour ranges from an empty string to an exception depending on the code path, and an exception in an observer will roll back your model save.
• Don't log the key. Error logging that dumps the full request will write Ocp-Apim-Subscription-Key into storage/logs. Scrub it in a Monolog processor.
• Check the SSL options. Older cURL-based clients sometimes set CURLOPT_SSL_VERIFYPEER => false. If you find that, fix it before it ships.
• Treat the package as vendored source. 17 stars, MIT, no release since 2016 — there is no upstream to fix anything for you. Copy the class into app/Support/ under your own namespace, or skip it: the current Translator v3 REST surface is a single POST with a JSON body, and a small typed client you control will be more maintainable than an adapter around an abandoned one.
