NOTE: If you delete or disable a user who has been used in a Web Key as the creator of a record, the records will no longer be generated. In this circumstance, you should edit the Web Key and recreate the web form.
Click Save & Close. The new key will now appear in the grid on the right. Click on the key to open it and click on Form.
This will download an HTML form that can be used in your website. Your developer will, most probably, want to edit the form so that only the relevant fields are shown on the resulting form.
NOTE: If your Case or Lead record contains custom fields these will appear on the resulting web form, but only if the show by default checkbox on the custom field has been ticked.
