Once the request is received, the mandate status is updated to **Pending** at LotusPay’s end. The API response includes an **authentication (auth) link** , along with additional details such as the **link expiry time** . The customer must use this auth link to authenticate the request within the specified expiry period. Simultaneously, a webhook is triggered to the merchant’s configured webhook URL with the event type `mandate.pending`, indicating that the request has been successfully created at LotusPay’s end. If the customer’s authentication journey fails, the mandate is reverted to its previous state without any changes. Additionally, a webhook is sent to the merchant’s webhook URL with the event type `mandate..failed` (_where_ ``_can be_ `amend`_,_ `pause`_,_ `resume`_, or_ `cancel`). If the customer successfully completes the authentication journey, the requested action is applied to the mandate, and a webhook with the event type `mandate..success` is sent to the merchant. Optionally, while initiating the API request, merchants can also provide `return_url` and `auth_mode` within the redirect payload. After the authentication journey is completed, LotusPay will redirect the customer to the specified `return_url`. Additionally, the provided `auth_mode` will be used as the default authentication mode during the customer’s authentication journey. **Note:** An authentication link can only be used once by the customer. If the authentication fails or the link expires, the merchant must initiate a **new request** to generate a fresh authentication link. --- ## See Also - [Types of events](https://juspay.io/in/docs/lotuspay/web/core-resources/types-of-events) - [Amend API](https://juspay.io/in/docs/lotuspay/web/mandate-management-apis/amend-api)
