We are currently looking for beta testers of our element extension development process. This would mean testing how the Extension API together with the Core API works in building element extensions. If you are interested in becoming a beta tester for building your own custom element extensions to HammerKit then please follow these steps:

1. Open an account on our staging environment at http://accountmanager.stage.hammerkit.com/.
2. Create into this account a site where you will test building your own element extensions.
3. Next you need an SFTP account in order to make writing the extension's files easier directly to the server. For this SFTP account please contact Peter Parkkali at peter.parkkali@hammerkit.com and tell him for which site you want the SFTP account to be opened. For this you can copy and paste the URL of the site into the email message.
4. When you have the SFTP account details, log in and navigate to the folder "public_html/HammerKit/ext/elements/". Under this folder are all the external element extension folders. Here you can now create your own element extension according to the rules explained in detail in the article about element extensions.

See the Wiki Article for a more comprehensive explanation. 

If you have questions or feedback to give about how the APIs work, please send it to api@hammerkit.com
