I've already certified the app in the developer account.
We have an existing merchant account that we would like to integrate with Payeezy.
When I hit the 'Merchants' tab and select 'Add a Merchant', the only option I see is to - 'Sign up for a merchant account'.
I don't see an option to add an 'existing merchant account' as I read in the FAQs.
Could you please let us know how to resolve this issue?
Thanks in advance
