Everything your agent can do with Adyen and Returnless ## Triggers and actions 4 triggers · 26 actions - Trigger **New payment authorisation** Webhook AUTHORISATION: result of authorisation request. - Trigger **New refund** Webhook REFUND: result of refund request. - Action **Add payment** Starts a payment (authorisation) in Adyen Checkout for the given amount, payment method and merchant account, and returns the payment's PSP reference and result code. - Action **Add payment link** Creates an Adyen Pay by Link payment link that a shopper can open to pay the given amount. - Action **Cancel payment** Cancels an authorised payment that has not been captured yet, releasing the funds back to the shopper. The final outcome arrives later in Adyen's CANCELLATION webhook. - Action **Capture payment** Captures an authorised payment (full or partial amount). Adyen processes the capture asynchronously: the response always has status "received" and the final outcome arrives later in a CAPTURE webhook. - Action **Delete stored payment method** Deletes (disables) a shopper's stored payment details token in Adyen. - Action **Get payment link** Retrieves the details of a payment link, including its amount, status (active, completed, expired or paymentPending), url and expiry. - Action **List payment methods** Retrieves the payment methods available for a transaction, based on details such as amount, country and currency, plus the shopper's stored payment methods when a shopper reference is given. - Action **List stored payment methods** Lists the tokens for payment details stored for a shopper, with a summary of each stored card or account. - Action **Refund payment** Refunds a captured Adyen payment, fully or partially. Adyen acknowledges the request immediately; the final outcome arrives later in a REFUND notification. - Action **Update payment link** Updates the status of an Adyen payment link.
