# Best Practices

## Catalog Refresh

Xoxoday recommends that you refresh your catalog once every 24 hours to fetch the latest information about the available gift cards.

## Use of PO Number

Xoxoday recommends that you implement the PO number functionality to avoid duplicate orders being placed.

## API Time Out

Xoxoday recommends that you should wait till 30 seconds to get a response from the API. This is because of API lag in our vendor systems.

## Error Code Handling

Xoxoday provides a wide variety of error codes in the API response. Please use them to fine tune the error handling at your end.
