 * In Contact Form 7, when I click on the PDF option and get to the Form-tag Generator:
   PDF Form page and choose a PDF file to upload, I end up receiving the following
   message:
 * Key Required
 * Where is the key supposed to be entered?
 * Thanks

 * Usually the key is generated automatically. However, if your wp admin email is
   invalid, this will fail. You can manually generate the key here: [https://pdf.ninja/](https://pdf.ninja/)
 * Once you generate a key, you have to import it on your site.
 * The key is located on Contact Form 7 ‘Integrations’ page ([https://yourdomain.com/wp-admin/admin.php?page=wpcf7-integration](https://yourdomain.com/wp-admin/admin.php?page=wpcf7-integration)).
   Click the edit button and you will be directed to this url: [https://yourdomain.com/wp-admin/admin.php?page=wpcf7-integration&service=pdf_ninja&action=edit](https://yourdomain.com/wp-admin/admin.php?page=wpcf7-integration&service=pdf_ninja&action=edit)
 * Once there, you can paste the key and save. This should fix your issue. Let me
   know if this doesn’t work.
