Go to Configuration / bookings & payments / Form 1 [Conference registration] / 2. Form access.
Make sure that the payment form is active, in section 1. Otherwise, the form will not be accessible, no matter what permissions you set.
Section 2 contains several functions, which allow you to: - define the users allowed access, - to set deadlines on this access, - to prevent editing of the form, if relevant. In this case, allowed users can view their order and download an invoice or a receipt, but they cannot edit the form.
Allow access to all users
The figure below shows how to set the permissions so that all users can access the form.
Allow access to a small list of users, for testing
Payment forms are often set up at a later stage than the submissions. When this happens, the configuration of the payment module occurs on a live site that is already accessed by the participants. You can restrict access to administrators or other users involved in the setup, so that they can access the forms on their accounts to view it and simulate payments in test mode. Once the tests are completed and you decide to go live, you can lift this restriction and allow all, or accepted users, as described above, to access the form.
The restriction to a select number of users is shown in the figure below. General access to the form must be disabled, while the list of authorised users, identified by their user-ids, must be provided. This list can be modified at will, but should be erased when going live. In this example, only users 1,2, 7, 8 an 9 will be able to have access.
Set time limits on the availability of the form
Access to the form can be further restricted by setting time limits, as shown in the figure below.
