# Token Credential Sample
|
||
|
|
|
||
|
|
This sample demonstrates how to configure a custom connection resolver when using Netherite in an Azure Functions application.
|
||
|
|
|
||
|
|
## Why you may want to use a custom resolver
|
||
|
|
|
||
|
|
A custom connection resolver is appropriate if you want more control over how connection names are resolved to connection information. For example:
|
||
|
|
|
||
|
|
- It allows you to construct your own Token Credential.
|
||
|
|
- It allows you to use your own configuration logic for resolving connection names, as opposed to following the default mechanism defined by Azure Functions.
|
||
|
|
|
||
|
|
For this sample, we use the default Azure Identity credential as provided by the Azure.Identity package.
|
||
|
|
|
||
|
|
## Configuration Prerequisites
|
||

2. Create a new Azure Event Hubs namespace, or reuse an existing one (that is not currently in use)
|
||
|
|
3. Make sure you have [Storage Blob Data Contributor](https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#storage-blob-data-contributor) and [Storage Table Data Contributor](https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#storage-table-data-contributor) permissions for the storage account.
|
||
|
|
4. Make sure you have [Azure Event Hubs Data Owner](https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#azure-event-hubs-data-owner) permission for the event hubs namespace.
|
||
|
|
5. Set `MyConnection__accountName` to contain the name of the storage account, using an environment variable or a function app configuration setting,
|
||
|
|
6. Set `MyConnection__eventHubsNamespaceName` to contain the name of the Event Hubs namespace, using an environment variable or a function app configuration setting.
