# Using dashboard
For using 0xcert API, you will need credits which are dapp tokens derived from ZXC tokens. So if you are a ZXC holder, you can easily convert your tokens into credits via our latest product: the 0xcert API Dashboard.
Dashboard gives you an overall overview of you recent API activity. You can check:
- number of all requests your dapp made,
- number of mutations and
- number of queries.
You also have an overview of your deployed ledgers and most importantly, your current credit balance.
To use the Dashboard, you need an existing Ethereum address to manage your ledgers. The wallet needs to be handled by either Metamask bridge. So if you don't have any, you first have to create one. Once your client is ready, you can login to the dashboard.
In each case you'll be asked to sign a signature request. At this point no funds are required; it's just a decentralized way to login into the dashboard with your personal wallet. So just hit the
Sign button. No email or passwords needed. Neat! Blockchain's dope.
You can get top up your balance easily through
Deposit credits button in a balance window. Read more about getting credits in the guide here. Bellow credits you have a graph that shows costs you spent per day.
Unused credits can be easily be withdrawn too. Note that they will be converted into ZXC tokens, since credit dapp tokens are only available and usable inside the 0xcert API environment.
On mainnet, you need to provide your valid details for accounting purposes. You will be prompt to provide them before accessing the Dashboard.
In Requests section you can find a list of all queries and mutations your dapp made to an API client. By clicking on each line, you get all the details of specific request, so you can easily debug your dapp.
In Ledgers section you can see all deployed ledgeers and theirs Ethereum addresses.
Webhooks are a way that apps can send automated messages or information to your other app, when specific event occurs. You can subscribe to:
- Order request changed events
- Order request errors events
- Deploy request changed events
- Deploy request errors events
- Approve request changed events
- Approve request errors events
If none of the options is selected, the account will be subscribed to all of them and will send all events to defined webhooks URL.
