The ePDQ payment option lets customers pay you using a credit card or debit card.

Setting up ePDQ in your shop

You can set up ePDQ payment by clicking Payment in the shop admin panel menu, clicking ePDQ, and changing the following settings:

Status

Whether ePDQ is available as a payment method.

Mode

Whether to perform test payments or live payments.

PSPID

Your ePDQ PSPID. This will be supplied by ePDQ.

SHA-IN pass phrase

This is a secret value used to ensure the security of communications with ePDQ. A random value is automatically filled in for you.

SHA-OUT pass phrase

This is a secret value used to ensure the security of communications with ePDQ. A random value is automatically filled in for you.

Operation

Set to Sale to take the funds from the customer as soon as possible. Set to Authorisation to guarantee the availability of funds for 6 days and allow funds to be taken up to 30 days after the initial transaction. Set to Pre-authorisation to check the customer details only; this does not guarantee the funds are available, but allows funds to be taken in stages and up to 90 days after the initial transaction.

Logging in to your ePDQ account

To log in to your ePDQ test account, go to the ePDQ test back office and enter your PSPID and password. To log in to your ePDQ production account, go to the ePDQ production back office and enter your PSPID and password.

Testing and going live

To perform the test purchase, first ensure that ePDQ is set to test mode on the ePDQ page in the shop management panel. Go through the process of making a purchase from your shop, exactly as if you were a normal customer, choosing ePDQ as the payment method. You will be taken to the ePDQ test server to make a payment. The test server only accepts the following card numbers:

If the test transaction is successful, you will be taken back to your shop and receive an e-mail confirming the transaction. After a successful test transaction, you set up your live account by logging in to the ePDQ production back office, as described above. If your site itself is not yet live, you will need to determine your live referring URL and response URL. These will be the same as the URLs displayed in the shop management panel, but with the temporary address of your site (for example, https://s1.itseeze.co.uk/sites/example/) replaced with the address your site will use when live (for example, https://example.com/).

You can then switch to live mode on the ePDQ page in the shop management panel. Once your site itself is live you may wish to make a real purchase from your shop and then void the transaction, in order to be completely certain that your account has gone live correctly.
