On October 9 2021 we will be retiring the v0 API endpoint at https://my.opalstack.com/api/v0/.
If you're using Opalstack's API then please update your code to use the v1 endpoint https://my.opalstack.com/api/v1/.
The API v1 endpoint is documented at https://my.opalstack.com/api/v1/doc/.
The WebFaction migration tool (wfmigrate) uses the old v0 endpoint, so that tool will be retired as well. WebFaction is officially shut down so the tool no longer has any use.
If you have any questions or concerns then please email them to support @ opalstack.com and one of our team will get back to you.
