Telnyx AI Assistants Java

Telnyx AI Assistants - Java

Installation

<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx</artifactId>
    <version>6.89.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.89.0")

Setup

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:

import com.telnyx.sdk.models.ai.assistants.AssistantCreateParams;
import com.telnyx.sdk.models.ai.assistants.InferenceEmbedding;
AssistantCreateParams params = AssistantCreateParams.builder()
    .instructions("You are a helpful assistant.")
    .name("my-resource")
    .model("openai/gpt-4o")
    .build();
InferenceEmbedding assistant = client.ai().assistants().create(params);

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().

Reference Use Rules

Do not invent Telnyx parameters, enums, response fields, or webhook fields.

• If the parameter, enum, or response field you need is not shown inline in this skill, read references/api-details.md before writing code.
• Before using any operation in ## Additional Operations, read the optional-parameters section and the response-schemas section.

Core Tasks

Create an assistant

Assistant creation is the entrypoint for any AI assistant integration. Agents need the exact creation method and the top-level fields returned by the SDK.

client.ai().assistants().create() — POST /ai/assistants

import com.telnyx.sdk.models.ai.assistants.AssistantCreateParams;
import com.telnyx.sdk.models.ai.assistants.InferenceEmbedding;

AssistantCreateParams params = AssistantCreateParams.builder()
    .instructions("You are a helpful assistant.")
    .name("my-resource")
    .model("openai/gpt-4o")
    .build();
InferenceEmbedding assistant = client.ai().assistants().create(params);

Primary response fields:

• assistant.id
• assistant.name
• assistant.model
• assistant.instructions
• assistant.createdAt
• assistant.conversationFlow

Chat with an assistant

Chat is the primary runtime path. Agents need the exact assistant method and the response content field.

client.ai().assistants().chat() — POST /ai/assistants/{assistant_id}/chat

import com.telnyx.sdk.models.ai.assistants.AssistantChatParams;
import com.telnyx.sdk.models.ai.assistants.AssistantChatResponse;

AssistantChatParams params = AssistantChatParams.builder()
    .assistantId("550e8400-e29b-41d4-a716-446655440000")
    .content("Tell me a joke about cats")
    .conversationId("42b20469-1215-4a9a-8964-c36f66b406f4")
    .build();
AssistantChatResponse response = client.ai().assistants().chat(params);

Primary response fields:

• response.content

Create an assistant test

Test creation is the main validation path for production assistant behavior before deployment.

client.ai().assistants().tests().create() — POST /ai/assistants/tests

import com.telnyx.sdk.models.ai.assistants.tests.AssistantTest;
import com.telnyx.sdk.models.ai.assistants.tests.TestCreateParams;

TestCreateParams params = TestCreateParams.builder()
    .destination("+15551234567")
    .instructions("Act as a frustrated customer who received a damaged product. Ask for a refund and escalate if not satisfied with the initial response.")
    .name("Customer Support Bot Test")
    .addRubric(TestCreateParams.Rubric.builder()
        .criteria("Assistant responds within 30 seconds")
        .name("Response Time")
        .build())
    .addRubric(TestCreateParams.Rubric.builder()
        .criteria("Provides correct product information")
        .name("Accuracy")
        .build())
    .build();
AssistantTest assistantTest = client.ai().assistants().tests().create(params);

Primary response fields:

• assistantTest.testId
• assistantTest.name
• assistantTest.destination
• assistantTest.createdAt
• assistantTest.instructions
• assistantTest.description

Additional Operations

Use the core tasks above first. The operations below are indexed here with exact SDK methods and required params; use references/api-details.md for full optional params, response schemas, and lower-frequency webhook payloads. Before using any operation below, read the optional-parameters section and the response-schemas section so you do not guess missing fields.

For exhaustive optional parameters, full response schemas, and complete webhook payloads, see references/api-details.md.
