DeepL Translation Memories API

The translation memory endpoints allow you to manage your account's translation memories, used to store and reuse previously created translations. You can list and retrieve translation memories, page through their stored segments, create one by importing a TMX file, export one back to TMX, and delete one. Editing the contents of an existing translation memory is not supported; import a new one instead. Importing and exporting run as background jobs. Create the job, then poll `GET /v3/translation_memories/jobs/{job_id}` until it reports `completed`. Translation memories can be used in text translation requests by specifying the `translation_memory_id` parameter to denote a specific translation memory and the `translation_memory_threshold` which defines the minimum matching percentage required for a translation memory segment to be applied (recommended to be 75% or higher). A translation request fails with `404` if the translation memory does not exist or does not cover the requested language pair.
