eMandate authorisation can return an error if the supplied details are incorrect, if the customer denies authorisation, or for technical reasons. You'll be notified instantly. Most error types can be easily rectified.
Note that eMandate authorisation errors are different to mandate failures.
eMandate authorisation in ONMAGS (NPCI's Online Mandate Approval Gateway System) can return errors due to various reasons. Click here to see a full list of reasons.
eMandate authorisation can return an error on the destination bank website if that bank rejects the mandate authorisation or has a technical issue. If the error is a technical issue, you may report it to LotusPay Support, we will report it to NPCI, and NPCI will report it to the destination bank and ask them to fix it.
When an eMandate authorisation error occurs, LotusPay informs you via webhook if you have provided a webhook URL. You can also view the error in the LotusPay dashboard on the mandate page.
Depending on your integration method, your customer can reuse the same eMandate link or you can create a new one for them.
