Telnyx Verify - 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.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 and retry with exponential backoff
        Thread.sleep(1000);
    }
}

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()`.

Lookup phone number data

Returns information about the provided phone number.

`GET /number_lookup/{phone_number}`

import com.telnyx.sdk.models.numberlookup.NumberLookupRetrieveParams;
import com.telnyx.sdk.models.numberlookup.NumberLookupRetrieveResponse;

NumberLookupRetrieveResponse numberLookup = client.numberLookup().retrieve("+18665552368");

Returns: `caller_name` (object), `carrier` (object), `country_code` (string), `fraud` (string | null), `national_format` (string), `phone_number` (string), `portability` (object), `record_type` (string)

List verifications by phone number

`GET /verifications/by_phone_number/{phone_number}`

import com.telnyx.sdk.models.verifications.byphonenumber.ByPhoneNumberListParams;
import com.telnyx.sdk.models.verifications.byphonenumber.ByPhoneNumberListResponse;

ByPhoneNumberListResponse byPhoneNumbers = client.verifications().byPhoneNumber().list("+13035551234");

Returns: `created_at` (string), `custom_code` (string | null), `id` (uuid), `phone_number` (string), `record_type` (enum: verification), `status` (enum: pending, accepted, invalid, expired, error), `timeout_secs` (integer), `type` (enum: sms, call, flashcall, whatsapp), `updated_at` (string), `verify_profile_id` (uuid)

Verify verification code by phone number

`POST /verifications/by_phone_number/{phone_number}/actions/verify` — Required: `code`, `verify_profile_id`

import com.telnyx.sdk.models.verifications.byphonenumber.actions.ActionVerifyParams;
import com.telnyx.sdk.models.verifications.byphonenumber.actions.VerifyVerificationCodeResponse;

ActionVerifyParams params = ActionVerifyParams.builder()
    .phoneNumber("+13035551234")
    .code("17686")
    .verifyProfileId("12ade33a-21c0-473b-b055-b3c836e1c292")
    .build();
VerifyVerificationCodeResponse verifyVerificationCodeResponse = client.verifications().byPhoneNumber().actions().verify(params);

Returns: `phone_number` (string), `response_code` (enum: accepted, rejected)

Trigger Call verification

`POST /verifications/call` — Required: `phone_number`, `verify_profile_id`

Optional: `custom_code` (string | null), `extension` (string | null), `timeout_secs` (integer)

import com.telnyx.sdk.models.verifications.CreateVerificationResponse;
import com.telnyx.sdk.models.verifications.VerificationTriggerCallParams;

VerificationTriggerCallParams params = VerificationTriggerCallParams.builder()
    .phoneNumber("+13035551234")
    .verifyProfileId("12ade33a-21c0-473b-b055-b3c836e1c292")
    .build();
CreateVerificationResponse createVerificationResponse = client.verifications().triggerCall(params);

Returns: `created_at` (string), `custom_code` (string | null), `id` (uuid), `phone_number` (string), `record_type` (enum: verification), `status` (enum: pending, accepted, invalid, expired, error), `timeout_secs` (integer), `type` (enum: sms, call, flashcall, whatsapp), `updated_at` (string), `verify_profile_id` (uuid)

Trigger Flash call verification

`POST /verifications/flashcall` — Required: `phone_number`, `verify_profile_id`

Optional: `timeout_secs` (integer)

import com.telnyx.sdk.models.verifications.CreateVerificationResponse;
import com.telnyx.sdk.models.verifications.VerificationTriggerFlashcallParams;
