  <Card title="How can I check the reason why an end-customer was unable to make a payment?" icon="magnifying-glass" iconType="solid" href="/docs/how-can-i-check-the-reason-why-an-end-customer-was-unable-to-make-a-payment" horizontal>
    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.

  <Card title="How are micro-deposits monitored?" icon="money-bill-transfer" iconType="solid" href="/docs/how-are-micro-deposits-monitored" horizontal>
    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.

  <Card title="Are there any differences in the Plaid linking process depending on the specific bank or credit union?" icon="link" iconType="solid" href="/docs/are-there-any-differences-in-the-plaid-linking-process-depending-on-the-specific-bank-or-credit-union" horizontal>
    No, unless the bank/credit union is not supported by Plaid. In that case, Synctera will have to do the micro deposits verification.

  <Card title="Can the end-customer link multiple bank accounts via micro deposit account verification?" icon="building-columns" iconType="solid" href="/docs/can-the-end-customer-link-multiple-bank-accounts-via-micro-deposit-account-verification" horizontal>
    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.
