Google Text Translator

Translate one text or HTML input into a target language with Google Cloud Translation Basic and return the complete translation record.

Setup

Enable Cloud Translation API and billing in your Google Cloud project. Set x-goog-user-project in Translate with Google NMT to the project used for quota and billing. The authorized principal must have serviceusage.services.use on that project.

In Open Flow, store a valid, short-lived OAuth access token in a secret Variable and bind it to Auth Token (auth.token). The token needs https://www.googleapis.com/auth/cloud-translation or https://www.googleapis.com/auth/cloud-platform. Renew the Variable when the token expires. This workflow does not acquire or refresh tokens, and it contains no service-account key. Shared JSON contains no token or Variable binding.

Run with Text and a supported Target language code, such as de. In n8n, select Google Translate OAuth2 API credentials in Translate with Google NMT, set the same quota-project header and edit q and target in the JSON body. n8n manages OAuth2 and can refresh its stored tokens. The two formats have different token-management requirements.

Each run sends one input to one target language. The source language is detected automatically. Google’s HTML input format and NMT model defaults are retained; HTML tags are preserved and translated text may contain escaped entities. This template does not decode or rewrite the returned text, use a custom model, translate files or split long text into batches. Google’s request-size and language-support limits apply.

The full single-translation record is returned, including detected source language and any extra properties. A failed request or malformed result stops the run. No workflow retry is configured. Open Flow’s HTTP step has a 30-second execution budget.

Changes to the source

• Replace example text and language with user configuration.
• Make the billing/quota project explicit in both formats.
• Use a manually renewed secret access-token Variable in Open Flow and retain managed OAuth2 in n8n.
• Check that one translated-text record is returned before exposing it.
