Ticketmatic accounts can have multiple languages. This is also exposed in the API.

Before reading on, read the translation documentation first to understand how multi-language support works in the application.

Multi-language support in the API largely works the same way: by default all data is returned in the base language. In the API documentation you will notice how some fields have a type of mlstring: this indicates a string field that is translatable.

There are two ways to handle language support in the API:

  • Switching the client language
  • Using translation calls

Switching the client language

By default, all calls are handled in the default account language. You can override this by sending an HTTP Accept-Language header with a language code as value (en, nl, fr, …). Both input and output will then be handled in the requested language. Passing an invalid language code will cause a fallback to the default language.

Note that if a field is not translated, the value for the default account language will be returned as fallback. For instance: when requesting French if a user only configures the English labels for a price type will return the English labels.

PHP Library

To set the language in the PHP library, use the setLanguage() function on Client:


All subsequent calls when then be performed in the requested language.

Go Library

To set the language in the Go library, change the Language field on Client:

1c.Language = "nl"

All subsequent calls when then be performed in the requested language.

Translation calls

You can request and update all multi-language strings for an object in one call using the translations calls.

These calls accept and return objects with string keys and string values. For example:

2	"nameen": "Free ticket",
3	"namenl": "Gratis ticket",
4	"namefr": "Billet gratuit"

Each field has a key composed of the field name and the language code.
