# Verify transaction

After initializing a transaction, you transfer control to your customer to complete payment. Hence, online payments require you to always run a verification check even if you are informed that payment has been completed.

Transaction verification provides a way for you to confirm the status of a transaction. A transaction may be in a **`processing`** state if payment processor networks are having a slow day. However, once a transaction is completed, a verification request will let you know if it was successful or failed.

{% hint style="info" %}
**NOTE:** If a verified transaction is successful, you can give value to your customer as SwitchApp guarantees that payment has been received.
