Monolingual glossaries (v2 endpoints)

Manage glossaries using the v2 endpoints

This page documents v2 glossary endpoints, legacy endpoints that let you create and manage glossaries for a single language pair.

See here for information on v3 endpoints, which allow you to create, manage, and edit glossaries with entries in multiple language pairs. See here for an overview of the difference.

This page describes how to use the v2 endpoints to work with monolingual glossaries - glossaries that map phrases in one language to phrases in another language. If you're new to glossaries, we suggest you use v3 instead. v3 allows you to work with multilingual glossaries, and it lets you edit any glossaries as well.

For more on v3, see the main glossaries documentation page. To learn about the differences between v2 and v3, see here.

Listing language pairs

The /glossary-language-pairs endpoint lists all the language pairs - the source and target languages - that glossaries support. Since glossaries now work for all languages DeepL supports, this list will be quite long. We recommend that you instead use the /languages endpoint.

Example request: get glossary language pairs

curl -X GET 'https://api.deepl.com/v2/glossary-language-pairs' \

Example response (partial—one language pair)

{
  "supported_languages": [

    }
  ]
}

Editing a v2 glossary

v2 glossaries are immutable: once created, the glossary entries for a given glossary ID cannot be modified.

As a workaround for effectively editable glossaries, we suggest to identify glossaries by name instead of ID in your application and then use the following procedure for modifications:

download and store the current glossary's entries
locally modify the glossary entries
delete the existing glossary
create a new glossary with the same name
