Pin Payments setup is extremely easy:
Activate Pin Payments on your DPD account
1. Log in to DPD
2. For the store you'd like to activate Pin Payments on, go to Payment Methods
3. Find Pin in the list and click "+Add"
4. Open a new browser window or tab and go to http://pin.net.au and create an account or log in to your existing account
5. Once logged in to Pin, go to Account in the left menu
6. Copy and paste your Live Secret API Key to DPD.
Note: You need to use your Live Secret API Key and not your Test key. If your account is not yet approved for Live transactions, you will need to complete that verification with Pin before you can use it with DPD.
