With this endpoint, you can inquire about the status of an tmx file upload job.
- If the value of the 'status' attribute is 'pending' or 'processing', you
should check this endpoint again later.
- If the 'status' is 'failed', the upload has failed to be parsed or validated.
- In case the upload job has been successful, you will receive a 'succeeded'
value for the 'status' attribute.
