# Payments

> **[How can I check the reason why an end-customer was unable to make a payment?](https://docs.synctera.com/docs/how-can-i-check-the-reason-why-an-end-customer-was-unable-to-make-a-payment.md)**
>
> Use the Transactions API. For v0, check the "Get a pending transaction" endpoint under data->reason. For v1, use the "Get a transaction" endpoint under data->decline\_reason.

> **[How are micro-deposits monitored?](https://docs.synctera.com/docs/how-are-micro-deposits-monitored.md)**
>
> Micro-deposits are monitored by Plaid, not Synctera. Plaid pushes two credits and a debit to the end-customer's account. The end-customer confirms the deposits via the Plaid UI in the Synctera app.

> **[Are there any differences in the Plaid linking process depending on the specific bank or credit union?](https://docs.synctera.com/docs/are-there-any-differences-in-the-plaid-linking-process-depending-on-the-specific-bank-or-credit-union.md)**
>
> No, unless the bank/credit union is not supported by Plaid. In that case, Synctera will have to do the micro deposits verification.

> **[Can the end-customer link multiple bank accounts via micro deposit account verification?](https://docs.synctera.com/docs/can-the-end-customer-link-multiple-bank-accounts-via-micro-deposit-account-verification.md)**
>
> Yes, as long as it's not the same bank account multiple times. Synctera has a configuration to prevent linking the same external account across customers, but this can be turned off upon request.
