The translation endpoints let you translate text using AI (powered by Meta’s M2M-100 model via Workers AI). Translations are cached to avoid redundant processing.

​
Translate text

POST /api/translate
Translates one or more strings into a target language. Request body:
​
text
string
A single string to translate. Use texts instead for batch mode.
​
texts
array
An array of strings to translate. Maximum 200 strings per request. Use this for batch mode instead of text.
​
to
string
required
BCP 47 language code of the target language (e.g., "es", "fr", "pt")
​
from
string
BCP 47 language code of the source language. Defaults to "en" if omitted.
Example — translate a single string: 
curl -X POST https://app.credentialsportal.com/api/translate \
  -H "Authorization: Bearer ck_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Welcome to Credentials Portal",
    "to": "es"
  }'
Response: 
{
  "translated": "Bienvenido al Portal de Credenciales",
  "from": "en",
  "to": "es"
}
Example — translate multiple strings: 
curl -X POST https://app.credentialsportal.com/api/translate \
  -H "Authorization: Bearer ck_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "texts": ["Hello", "Goodbye", "Thank you"],
    "to": "fr"
  }'
Response: 
{
  "translated": ["Bonjour", "Au revoir", "Merci"],
  "from": "en",
  "to": "fr"
}

​
List supported languages

GET /api/translate/languages
Returns all supported languages with their BCP 47 codes and display names (in both English and the native script). Example: 
curl https://app.credentialsportal.com/api/translate/languages \
  -H "Authorization: Bearer ck_your_api_key"
Response: 
{
  "languages": {
    "en": ["English", "English"],
    "es": ["Spanish", "Español"],
    "fr": ["French", "Français"],
    "pt": ["Portuguese", "Português"],
    "de": ["German", "Deutsch"],
    "zh": ["Chinese", "中文"]
  }
}
Each entry is an array of [englishName, nativeName]. 70+ languages are supported.

​
Translation in messages

Message translation happens automatically — when a user reads a conversation, each message is translated into their language on the fly. You don’t need to call the translation endpoint yourself for messaging. The POST /api/translate endpoint is useful for translating other content — such as custom field values, course names, or external data you’re importing.
