Telnyx Numbers - Java

Installation

<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx</artifactId>
    <version>6.95.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.95.0")

Setup

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

// fromEnv() reads TELNYX_API_KEY and TELNYX_PUBLIC_KEY (the public key is required for
// client.webhooks().unwrap() — webhook verification)
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.availablephonenumbers.AvailablePhoneNumberListParams;
import com.telnyx.sdk.models.availablephonenumbers.AvailablePhoneNumberListResponse;
import com.telnyx.sdk.errors.TelnyxServiceException;

try {
    AvailablePhoneNumberListResponse availablePhoneNumbers = client.availablePhoneNumbers().list();
} 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, then retry the request (bounded exponential backoff)
        Thread.sleep(1000);
        // ...retry the call here (give up after a few attempts)
    }
    throw e; // Re-throw: a failed request must never look like success to the caller
}

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](references/api-details.md) before writing code.
• Before using any operation in `## Additional Operations`, read [the optional-parameters section](references/api-details.md#optional-parameters) and [the response-schemas section](references/api-details.md#response-schemas).

Core Tasks

Search available phone numbers

Number search is the entrypoint for provisioning. Agents need the search method, key query filters, and the fields returned for candidate numbers.

`client.availablePhoneNumbers().list()` — `GET /available_phone_numbers`

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `filter` | object | No | Consolidated filter parameter (deepObject style). |

import com.telnyx.sdk.models.availablephonenumbers.AvailablePhoneNumberListParams;
import com.telnyx.sdk.models.availablephonenumbers.AvailablePhoneNumberListResponse;

AvailablePhoneNumberListResponse availablePhoneNumbers = client.availablePhoneNumbers().list();

Response wrapper:

• items: `availablePhoneNumbers.data`
• pagination: `availablePhoneNumbers.meta`

Primary item fields:

• `phoneNumber`
• `recordType`
• `quickship`
• `reservable`
• `bestEffort`
• `costInformation`

Create a number order

Number ordering is the production provisioning step after number selection.

`client.numberOrders().create()` — `POST /number_orders`

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `phoneNumbers` | array[object] | Yes | | | `connectionId` | string (UUID) | No | Identifies the connection associated with this phone number. | | `messagingProfileId` | string (UUID) | No | Identifies the messaging profile associated with the phone n... | | `billingGroupId` | string (UUID) | No | Identifies the billing group associated with the phone numbe... | | ... | | | +1 optional params in [references/api-details.md](references/api-details.md) |

import com.telnyx.sdk.models.numberorders.NumberOrderCreateParams;
import com.telnyx.sdk.models.numberorders.NumberOrderCreateResponse;

NumberOrderCreateParams params = NumberOrderCreateParams.builder()

    .addPhoneNumber(

        NumberOrderCreateParams.PhoneNumber.builder()

            .phoneNumber("+18005550101")

            .build()

        )

    .build();

NumberOrderCreateResponse numberOrder = client.numberOrders().create(params);

Primary response fields:

• `numberOrder.data.id`
• `numberOrder.data.status`
• `numberOrder.data.phoneNumbersCount`
• `numberOrder.data.requirementsMet`
• `numberOrder.data.messagingProfileId`
• `numberOrder.data.connectionId`

Check number order status

Order status determines whether provisioning completed or additional requirements are still blocking fulfillment.

`client.numberOrders().retrieve()` — `GET /number_orders/{number_order_id}`

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `numberOrderId` | string (UUID) | Yes | The number order ID. |

import com.telnyx.sdk.models.numberorders.NumberOrderRetrieveResponse;
