We have a Zapier Trigger App on Zapier called "Get New Website Credentials in WordPress Website Creator" with which you can fetch the data of your newly created websites. However, Zapier does not allow the transfer of sensitive data such as passwords, etc. If you absolutely need this data in your software you can use this hook. In addition, this data transfer is faster because the data is sent immediately after successful installation, whereas our Zapier Trigger App "Get New Website Credentials in WordPress Website Creator" is a pull app and fetches the data at a specified interval.
