# Telnyx Webrtc - Java

## Installation

```text
<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx</artifactId>
    <version>6.36.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.36.0")
```

## Setup

```java
import com.telnyx.sdk.client.TelnyxClient;
import com.telnyx.sdk.client.okhttp.TelnyxOkHttpClient;

TelnyxClient client = TelnyxOkHttpClient.fromEnv();
```

All examples below assume `client` is already initialized as shown above.

## Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422),
or authentication errors (401). Always handle errors in production code:

```java
import com.telnyx.sdk.errors.TelnyxServiceException;

try {
    var result = client.messages().send(params);
} catch (TelnyxServiceException e) {
    System.err.println("API error " + e.statusCode() + ": " + e.getMessage());
    if (e.statusCode() == 422) {
        System.err.println("Validation error — check required fields and formats");
    } else if (e.statusCode() == 429) {
        // Rate limited — wait and retry with exponential backoff
        Thread.sleep(1000);
    }
}
```

Common error codes: `401` invalid API key, `403` insufficient permissions,
`404` resource not found, `422` validation error (check field formats),
`429` rate limited (retry with exponential backoff).

## Important Notes

- **Pagination:** List methods return a page. Use `.autoPager()` for automatic iteration: `for (var item : page.autoPager()) { ... }`. For manual control, use `.hasNextPage()` and `.nextPage()`.

## List mobile push credentials

`GET /mobile_push_credentials`

```java
import com.telnyx.sdk.models.mobilepushcredentials.MobilePushCredentialListPage;
import com.telnyx.sdk.models.mobilepushcredentials.MobilePushCredentialListParams;

MobilePushCredentialListPage page = client.mobilePushCredentials().list();
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Creates a new mobile push credential

`POST /mobile_push_credentials` — Required: `type`, `certificate`, `private_key`, `alias`

```java
import com.telnyx.sdk.models.mobilepushcredentials.MobilePushCredentialCreateParams;
import com.telnyx.sdk.models.mobilepushcredentials.PushCredentialResponse;

MobilePushCredentialCreateParams.CreateMobilePushCredentialRequest.Ios params = MobilePushCredentialCreateParams.CreateMobilePushCredentialRequest.Ios.builder()
    .alias("LucyIosCredential")
    .certificate("-----BEGIN CERTIFICATE----- MIIGVDCCBTKCAQEAsNlRJVZn9ZvXcECQm65czs... -----END CERTIFICATE-----")
    .privateKey("-----BEGIN RSA PRIVATE KEY----- MIIEpQIBAAKCAQEAsNlRJVZn9ZvXcECQm65czs... -----END RSA PRIVATE KEY-----")
    .build();
PushCredentialResponse pushCredentialResponse = client.mobilePushCredentials().create(params);
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Retrieves a mobile push credential

Retrieves mobile push credential based on the given `push_credential_id`

`GET /mobile_push_credentials/{push_credential_id}`

PushCredentialResponse pushCredentialResponse = client.mobilePushCredentials().retrieve("0ccc7b76-4df3-4bca-a05a-3da1ecc389f0");
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Deletes a mobile push credential

Deletes a mobile push credential based on the given `push_credential_id`

`DELETE /mobile_push_credentials/{push_credential_id}`

```java
import com.telnyx.sdk.models.mobilepushcredentials.MobilePushCredentialDeleteParams;
