# storeCredentials(forBorderAgent:activeOperationalDataSet:completion:)

Stores Thread network credentials into the framework database that a Border Agent
provides.

```
func storeCredentials(forBorderAgent borderAgentID: Data, activeOperationalDataSet: Data, completion: @escaping @Sendable ((any Error)?) -> Void)
```

## Parameters

`borderAgentID`

The identifer of an active Thread network Border Agent.

`activeOperationalDataSet`

The essential operational parameters for the Thread network.

`completion`

The completion handler the framework calls after storing the credentials.

## Discussion> Important: You can call this method from synchronous code using a completion handler,
> as shown on this page, or you can call it as an asynchronous method that has the
> following declaration:
> 
> ```swift
> func storeCredentials(forBorderAgent borderAgentID: Data, activeOperationalDataSet: Data) async throws
> ```
> 
> For information about concurrency and asynchronous code in Swift, see <doc://com.apple.documentation/documentation/Swift/calling-objective-c-apis-asynchronously>.

The Border Agent is the software component running in the Thread Border Router responsible
for advertising itself in the Wi-Fi or Ethernet network.

The framework only stores credentials if it can find an mDNS record for the Border
Agent that contains the specified Border Agent identifier.

Call the method as follows:

```swift
func saveCredentials(borderAgentID: Data, activeOperationalDataSet: Data) async -> (Error?) {
    let client = THClient()
    var err:Error?
    do {
        err = try await client.storeCredentials(forBorderAgent: borderAgentID, activeOperationalDataSet: activeOperationalDataSet) as? Error
    } catch {
        err = error
    }
    return (err)
}
```
