Describe the flow you need, at any depth, and your agent builds it and tests every scenario before it ships. Everything your agent can do with Adyen and Postal Methods ## Triggers and actions 2 triggers · 12 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).
