Telnyx Texml - 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()`.

Fetch multiple call resources

Returns multiple call resources for an account. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls`

import com.telnyx.sdk.models.texml.accounts.calls.CallRetrieveCallsParams;
import com.telnyx.sdk.models.texml.accounts.calls.CallRetrieveCallsResponse;

CallRetrieveCallsResponse response = client.texml().accounts().calls().retrieveCalls("550e8400-e29b-41d4-a716-446655440000");

Returns: `calls` (array[object]), `end` (integer), `first_page_uri` (string), `next_page_uri` (string), `page` (integer), `page_size` (integer), `start` (integer), `uri` (string)

Initiate an outbound call

Initiate an outbound TeXML call. Telnyx will request TeXML from the XML Request URL configured for the connection in the Mission Control Portal.

`POST /texml/Accounts/{account_sid}/Calls` — Required: `Url`

Optional: `Texml` (object)

import com.telnyx.sdk.models.texml.accounts.calls.CallCallsParams;
import com.telnyx.sdk.models.texml.accounts.calls.CallCallsResponse;

CallCallsParams params = CallCallsParams.builder()
    .accountSid("550e8400-e29b-41d4-a716-446655440000")
    .params(CallCallsParams.Params.WithUrl.builder()
        .url("https://www.example.com/texml.xml")
        .build())
    .build();
CallCallsResponse response = client.texml().accounts().calls().calls(params);

Returns: `from` (string), `status` (string), `to` (string)

Fetch a call

Returns an individual call identified by its CallSid. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls/{call_sid}`

import com.telnyx.sdk.models.texml.accounts.calls.CallRetrieveParams;
import com.telnyx.sdk.models.texml.accounts.calls.CallRetrieveResponse;

CallRetrieveParams params = CallRetrieveParams.builder()
    .accountSid("550e8400-e29b-41d4-a716-446655440000")
    .callSid("550e8400-e29b-41d4-a716-446655440000")
    .build();
CallRetrieveResponse call = client.texml().accounts().calls().retrieve(params);

Returns: `account_sid` (string), `answered_by` (enum: human, machine, not_sure), `caller_name` (string), `date_created` (string), `date_updated` (string), `direction` (enum: inbound, outbound), `duration` (string), `end_time` (string), `from` (string), `from_formatted` (string), `price` (string), `price_unit` (string), `sid` (string), `start_time` (string), `status` (enum: ringing, in-progress, canceled, completed, failed, busy, no-answer), `to` (string), `to_formatted` (string), `uri` (string)

Update call

Update TeXML call. Please note that the keys present in the payload MUST BE formatted in CamelCase as specified in the example.

`POST /texml/Accounts/{account_sid}/Calls/{call_sid}`

import com.telnyx.sdk.models.texml.accounts.calls.CallUpdateParams;
import com.telnyx.sdk.models.texml.accounts.calls.CallUpdateResponse;
import com.telnyx.sdk.models.texml.accounts.calls.UpdateCall;

CallUpdateParams params = CallUpdateParams.builder()
    .accountSid("550e8400-e29b-41d4-a716-446655440000")
    .callSid("550e8400-e29b-41d4-a716-446655440000")
    .updateCall(UpdateCall.builder().build())
    .build();
CallUpdateResponse call = client.texml().accounts().calls().update(params);

Returns: `account_sid` (string), `answered_by` (enum: human, machine, not_sure), `caller_name` (string), `date_created` (string), `date_updated` (string), `direction` (enum: inbound, outbound), `duration` (string), `end_time` (string), `from` (string), `from_formatted` (string), `price` (string), `price_unit` (string), `sid` (string), `start_time` (string), `status` (enum: ringing, in-progress, canceled, completed, failed, busy, no-answer), `to`
