Biller Service

Accept payments for billers within your application.

Customer payment experience

Customer selects their desired biller from the available Biller Service list (Get Biller List Call).
Partner requests a Biller Hosted Page URL for the biller (Request Biller URL Call)
Customer is redirected to the Biller Hosted Page to enter their account details.
Customer clicks continue after entering their details, triggering a redirect with URL query parameters.
Partner intercepts the redirect and determines whether the customer has cancelled, encountered an error, or is ready to proceed.
The customer completes their payment on the Partner's application (Resolve Payment Call).

Payment Source generates a daily Request for Funds, which includes all paid (resolved) transactions (i.e. a batch) at 1am Pacific Time.
Partner pays the amount via EFT and sends a Remittance Advice to ar@paymentsource.ca.
Once funds are received, the transactions will be released and distributed to the respective billers.

All requests must include the API key provided by PSI in the x-api-key request header.
