# EDI Core: parse EDI files without envelopes

> EDI Core: parse EDI files without envelopes

Published Jan 10, 2022

Product: EDI platform

As a consumer of the /translate EDI core API, you now have the ability to parse EDI files that do **NOT** have envelopes. Before this enhancement, parsing a file without ISA/IEA GS/GE segments would result in a 422 response. Now, the EDI Core API will return a response based on the desired output parameters. The API response will identify the missing envelopes and elements for you.

**EDI Core: parse segments not in spec**

The /translate EDI core API has been updated to support the parsing of segments that are not part of a given X12 release. Before this update, such a segment would result in a 422 response. Now, the API will return a valid response that clearly identifies the segment in question.
