# Telnyx Messaging Hosted - 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

- **Phone numbers** must be in E.164 format (e.g., `+13125550001`). Include the `+` prefix and country code. No spaces, dashes, or parentheses.
- **Pagination:** List methods return a page. Use `.autoPager()` for automatic iteration: `for (var item : page.autoPager()) { ... }`. For manual control, use `.hasNextPage()` and `.nextPage()`.

## Send an RCS message

`POST /messages/rcs` — Required: `agent_id`, `to`, `messaging_profile_id`, `agent_message`

Optional: `mms_fallback` (object), `sms_fallback` (object), `type` (enum: RCS), `webhook_url` (url)

```java
import com.telnyx.sdk.models.messages.RcsAgentMessage;
import com.telnyx.sdk.models.messages.rcs.RcSendParams;
import com.telnyx.sdk.models.messages.rcs.RcSendResponse;

RcSendParams params = RcSendParams.builder()
    .agentId("Agent007")
    .agentMessage(RcsAgentMessage.builder().build())
    .messagingProfileId("550e8400-e29b-41d4-a716-446655440000")
    .to("+13125551234")
    .build();
RcSendResponse response = client.messages().rcs().send(params);
```

Returns: `body` (object), `direction` (string), `encoding` (string), `from` (object), `id` (string), `messaging_profile_id` (string), `organization_id` (string), `received_at` (date-time), `record_type` (string), `to` (array[object]), `type` (string), `wait_seconds` (float)

## Generate RCS deeplink

Generate a deeplink URL that can be used to start an RCS conversation with a specific agent.

`GET /messages/rcs/deeplinks/{agent_id}`

```java
import com.telnyx.sdk.models.messages.rcs.RcGenerateDeeplinkParams;
import com.telnyx.sdk.models.messages.rcs.RcGenerateDeeplinkResponse;

RcGenerateDeeplinkResponse response = client.messages().rcs().generateDeeplink("550e8400-e29b-41d4-a716-446655440000");
```

Returns: `url` (string)

## List all RCS agents

`GET /messaging/rcs/agents`

```java
import com.telnyx.sdk.models.messaging.rcs.agents.AgentListPage;
import com.telnyx.sdk.models.messaging.rcs.agents.AgentListParams;

AgentListPage page = client.messaging().rcs().agents().list();
```

Returns: `agent_id` (string), `agent_name` (string), `created_at` (date-time), `enabled` (boolean), `profile_id` (uuid), `updated_at` (date-time), `user_id` (string), `webhook_failover_url` (url), `webhook_url` (url)

## Retrieve an RCS agent

`GET /messaging/rcs/agents/{id}`

```java
import com.telnyx.sdk.models.messaging.rcs.agents.AgentRetrieveParams;
import com.telnyx.sdk.models.rcsagents.RcsAgentResponse;

RcsAgentResponse rcsAgentResponse = client.messaging().rcs().agents().retrieve("550e8400-e29b-41d4-a716-446655440000");
```

Returns: `agent_id` (string), `agent_name` (string), `created_at` (date-time), `enabled` (boolean), `profile_id` (uuid), `updated_at` (date-time), `user_id` (string), `webhook_failover_url` (url), `webhook_url` (url)

## Modify an RCS agent

`PATCH /messaging/rcs/agents/{id}`

Optional: `profile_id` (uuid), `webhook_failover_url` (url), `webhook_url` (url)

```java
import com.telnyx.sdk.models.messaging.rcs.agents.AgentUpdateParams;
import com.telnyx.sdk.models.rcsagents.RcsAgentResponse;

RcsAgentResponse rcsAgentResponse = client.messaging().rcs().agents().update("550e8400-e29b-41d4-a716-446655440000");
```

Returns: `agent_id` (string), `agent_name` (string), `created_at` (date-time), `enabled` (boolean), `profile_id` (uuid), `updated_at` (date-time), `user_id` (string), `webhook_failover_url` (url), `webhook_url` (url)

## Check RCS capabilities (batch)

`POST /messaging/rcs/bulk_capabilities` — Required: `agent_id`, `phone_numbers`

```java
import com.telnyx.sdk.models.messaging.rcs.RcListBulkCapabilitiesParams;
import com.telnyx.sdk.models.messaging.rcs.RcListBulkCapabilitiesResponse;

RcListBulkCapabilitiesParams params = RcListBulkCapabilitiesParams.builder()
    .agentId("TestAgent")
    .addPhoneNumber("+13125551234")
    .build();
RcListBulkCapabilitiesResponse response = client.messaging().rcs().listBulkCapabilities(params);
```

Returns: `agent_id` (string), `agent_name` (string), `features` (array[string]), `phone_number` (string), `record_type` (enum: rcs.capabilities)

## Check RCS capabilities

`GET /messaging/rcs/capabilities/{agent_id}/{phone_number}`

```java
import com.telnyx.sdk.models.messaging.rcs.RcRetrieveCapabilitiesParams;
import com.telnyx.sdk.models.messaging.rcs.RcRetrieveCapabilitiesResponse;

RcRetrieveCapabilitiesParams params = RcRetrieveCapabilitiesParams.builder()
    .agentId("550e8400-e29b-41d4-a716-446655440000")
    .phoneNumber("+13125550001")
