# Create a new version

POST https://{hostname}/edgeworkers/v1/ids/{edgeWorkerId}/versions
Content-Type: application/gzip

Create a new version of an EdgeWorker. In order to run this operation you need to build an [EdgeWorkers code bundle](https://techdocs.akamai.com/edgeworkers/docs/create-a-code-bundle) and save it in GZIP format. You need to provide the GZIP binary file in the request body, with a `Content-Type` of `application/gzip`.
