Telnyx Iot - 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.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, 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

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

Purchase eSIMs

Purchases and registers the specified amount of eSIMs to the current user's account. If `sim_card_group_id` is provided, the eSIMs will be associated with that group. Otherwise, the default group for the current user will be used.

`POST /actions/purchase/esims` — Required: `amount`

Optional: `product` (string), `sim_card_group_id` (uuid), `status` (enum: enabled, disabled, standby), `tags` (array[string]), `whitelabel_name` (string)

import com.telnyx.sdk.models.actions.purchase.PurchaseCreateParams;
import com.telnyx.sdk.models.actions.purchase.PurchaseCreateResponse;

PurchaseCreateParams params = PurchaseCreateParams.builder()
    .amount(10L)
    .build();
PurchaseCreateResponse purchase = client.actions().purchase().create(params);

Returns: `actions_in_progress` (boolean), `authorized_imeis` (array | null), `created_at` (string), `current_billing_period_consumed_data` (object), `data_limit` (object), `eid` (string | null), `esim_installation_status` (enum: released, disabled), `iccid` (string), `id` (uuid), `imsi` (string), `msisdn` (string), `record_type` (string), `resources_with_in_progress_actions` (array[object]), `sim_card_group_id` (uuid), `status` (object), `tags` (array[string]), `type` (enum: physical, esim), `updated_at` (string), `version` (string), `voice_enabled` (boolean)

Register SIM cards

Register the SIM cards associated with the provided registration codes to the current user's account. If `sim_card_group_id` is provided, the SIM cards will be associated with that group. Otherwise, the default group for the current user will be used.

`POST /actions/register/sim_cards` — Required: `registration_codes`

Optional: `sim_card_group_id` (uuid), `status` (enum: enabled, disabled, standby), `tags` (array[string])

import com.telnyx.sdk.models.actions.register.RegisterCreateParams;
import com.telnyx.sdk.models.actions.register.RegisterCreateResponse;
import java.util.List;

RegisterCreateParams params = RegisterCreateParams.builder()
    .registrationCodes(List.of(
      "0000000001",
      "0000000002",
      "0000000003"
    ))
    .build();
RegisterCreateResponse register = client.actions().register().create(params);

Returns: `actions_in_progress` (boolean), `authorized_imeis` (array | null), `created_at` (string), `current_billing_period_consumed_data` (object), `data_limit` (object), `eid` (string | null), `esim_installation_status` (enum: released, disabled), `iccid` (string), `id` (uuid), `imsi` (string), `msisdn` (string), `record_type` (string), `resources_with_in_progress_actions` (array[object]), `sim_card_group_id` (uuid), `status` (object), `tags` (array[string]), `type` (enum: physical, esim), `updated_at` (string), `version` (string), `voice_enabled` (boolean)

List bulk SIM card actions

This API lists a paginated collection of bulk SIM card actions. A bulk SIM card action contains details about a collection of individual SIM card actions.

`GET /bulk_sim_card_actions`

import com.telnyx.sdk.models.bulksimcardactions.BulkSimCardActionListPage;
import com.telnyx.sdk.models.bulksimcardactions.BulkSimCardActionListParams;

BulkSimCardActionListPage page = client.bulkSimCardActions().list();

Returns: `action_type` (enum: bulk_disable_voice, bulk_enable_voice, bulk_set_public_ips), `created_at` (string), `id` (uuid), `record_type` (string), `settings` (object), `sim_card_actions_summary` (array[object]), `updated_at` (string)

Get bulk SIM card action details

This API fetches information about a bulk SIM card action. A bulk SIM card action contains details about a collection of individual SIM card actions.

`GET /bulk_sim_card_actions/{id}`
