Response language

The API responds in English by default, or in French. The language applies to error messages and to content generated by eldo wallet.

The language is read in this order:

1. the ?lang=en query parameter
2. the x-lang: en header
3. the Accept-Language header

Error in English with ?lang=en

note

A few validation messages are always in English, even when you request French (for example departureDate must be a valid ISO date). Always test errorCode, never message.

Your pass content

The API language doesn't translate your passes: the text you send (details, terms, event name…) is displayed as is. For a multilingual audience, create one template per language, or adapt the pass fields for each customer.
