    The text-translation API currently consists of a single endpoint, `translate`, which is described below.
- name: TranslateDocuments
  description: |-
    The document translation API allows you to translate whole documents and supports the following file types and extensions:
      * `docx` - Microsoft Word Document
      * `pptx` - Microsoft PowerPoint Document
      * `xlsx` - Microsoft Excel Document
      * `pdf` - Portable Document Format
      * `htm / html` - HTML Document
      * `txt` - Plain Text Document
      * `xlf / xliff` - XLIFF Document, version 2.1
      * `srt` - SRT Document
- name: RephraseText
  description: |-
    The `rephrase` endpoint  is used to make corrections and adjustments to texts based on style or tone.
- name: ManageGlossaries
  description: |-
    The *glossary* functions allow you to create, inspect, and delete glossaries.
    Glossaries created with the glossary function can be used in translate requests by specifying the
    `glossary_id` parameter.
    If you encounter issues, please let us know at support@DeepL.com.

    The DeepL API supports glossaries in any combination of two languages from the following list, enabling a total of
    120 possible glossary language pairs:

    - DA (Danish)
    - DE (German)
    - EN (English)
    - ES (Spanish)
    - FR (French)
    - IT (Italian)
    - JA (Japanese)
    - KO (Korean)
    - NB (Norwegian (bokmål))
    - NL (Dutch)
    - PL (Polish)
    - PT (Portuguese)

        List of XML tags which never split sentences.


        For some XML files, finding tags with textual content and splitting sentences using those tags won't yield the best results. The following example shows the engine splitting sentences on `par` tags and proceeding to translate the parts separately, resulting in an incorrect translation:
         * Example request:
        ```
        <par>The firm said it had been </par><par> conducting an internal investigation.</par>
        ```
         * Example response:
        ```
        <par>Die Firma sagte, es sei eine gute Idee gewesen.</par><par> Durchführung einer internen Untersuchung.</par>
        ```


        As this can lead to bad translations, this type of structure should either be avoided, or the `non_splitting_tags` parameter should be set. The following example shows the same call, with the parameter set to `par`:
         * Example request:
        ```
        <par>The firm said it had been </par><par> conducting an internal investigation.</par>
        ```
         * Example response:
        ```
        <par>Die Firma sagte, dass sie</par><par> eine interne Untersuchung durchgeführt</par><par> habe</par><par>.</par>
        ```


        This time, the sentence is translated as a whole. The XML tags are now considered markup and copied into the translated sentence. As the translation of the words "had been" has moved to another position in the German sentence, the two par tags are duplicated (which is expected here).
