I've been trying to get a checksum token working with FormBuilder on WordPress but I can't get the format of the URL to work. I know in the FormBuilder UI it tells you what link to use for including the id in the link:
https://example.org/civicrm/renew-your-membership/#?Individual1=123 but it's not prefilling the form (which is set to current user) and security is set to User-Based.
Is there anything specific I should check for under permissions?
I've searched the forums and the web but I can't find any examples or documentation.
