# Modify Package metadata

Currently only `package_json_uri` and `api_endpoint` are modifyable. To signal to DSP Portals / Developers that your package is no longer in service, set your `api_endpoint` to `null`.

To modify package metadata: use the “modifypkg” action of the dappservices contract.

Using cleos:

```
cleos -u $DSP_ENDPOINT push action dappservices modifypkg "[\"$DSP_ACCOUNT\",\"$PACKAGE_ID\",\"ipfsservice1\",\"$DSP_ENDPOINT\",\"https://acme-dsp.com/modified-package1.dsp-package.json\"]" -p $DSP_ACCOUNT@active
```
