<!-- Maven -->
<dependency>

    <artifactId>telnyx</artifactId>
    <version>6.36.0</version>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.36.0")

Setup

java

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:

java

import com.telnyx.sdk.models.availablephonenumbers.AvailablePhoneNumberListParams;
import com.telnyx.sdk.models.availablephonenumbers.AvailablePhoneNumberListResponse;
AvailablePhoneNumberListResponse availablePhoneNumbers = client.availablePhoneNumbers().list();

Common error codes:

invalid API key,

insufficient permissions,

resource not found,

validation error (check field formats),

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 before writing code.
Before using any operation in
```
## Additional Operations
```
, read the optional-parameters section and the response-schemas section.

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).

java

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

java

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.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.

Primary response fields:

```
numberOrder.data.id
```
```
numberOrder.data.status
```
```

```
```
numberOrder.data.phoneNumbers
```
```
numberOrder.data.connectionId
```
