Telnyx Iot - JavaScript

Installation

npm install telnyx@6.74.2

Setup

import Telnyx from 'telnyx';

const client = new Telnyx({
  apiKey: process.env['TELNYX_API_KEY'], // This is the default and can be omitted
});

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:

try {
  const result = await client.messages.send({ to: '+13125550001', from: '+13125550002', text: 'Hello' });
} catch (err) {
  if (err instanceof Telnyx.APIConnectionError) {
    console.error('Network error — check connectivity and retry');
  } else if (err instanceof Telnyx.RateLimitError) {
    // 429: rate limited — wait and retry with exponential backoff
    const retryAfter = err.headers?.['retry-after'] || 1;
    await new Promise(r => setTimeout(r, retryAfter * 1000));
  } else if (err instanceof Telnyx.APIError) {
    console.error(`API error ${err.status}: ${err.message}`);
    if (err.status === 422) {
      console.error('Validation error — check required fields and formats');
    }
  }
}

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 an auto-paginating iterator. Use `for await (const item of result) { ... }` to iterate through all pages automatically.

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)

const purchase = await client.actions.purchase.create({ amount: 10 });

console.log(purchase.data);

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])

const register = await client.actions.register.create({
  registration_codes: ['0000000001', '0000000002', '0000000003'],
});

console.log(register.data);

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`

// Automatically fetches more pages as needed.
for await (const bulkSimCardActionListResponse of client.bulkSimCardActions.list()) {
  console.log(bulkSimCardActionListResponse.id);
}

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}`

const bulkSimCardAction = await client.bulkSimCardActions.retrieve(
  '6a09cdc3-8948-47f0-aa62-74ac943d6c58',
);

console.log(bulkSimCardAction.data);

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)
