Telnyx Storage - Java

Installation

<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx-java</artifactId>
    <version>6.26.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx-java:6.26.0")

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).

Get Bucket SSL Certificate

Returns the stored certificate detail of a bucket, if applicable.

GET /storage/buckets/{bucketName}/ssl_certificate

import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateRetrieveParams;
import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateRetrieveResponse;

SslCertificateRetrieveResponse sslCertificate = client.storage().buckets().sslCertificate().retrieve("");

Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)

Add SSL Certificate

Uploads an SSL certificate and its matching secret so that you can use Telnyx's storage as your CDN.

PUT /storage/buckets/{bucketName}/ssl_certificate

import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateCreateParams;
import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateCreateResponse;

SslCertificateCreateResponse sslCertificate = client.storage().buckets().sslCertificate().create("");

Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)

Remove SSL Certificate

Deletes an SSL certificate and its matching secret.

DELETE /storage/buckets/{bucketName}/ssl_certificate

import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateDeleteParams;
import com.telnyx.sdk.models.storage.buckets.sslcertificate.SslCertificateDeleteResponse;

SslCertificateDeleteResponse sslCertificate = client.storage().buckets().sslCertificate().delete("");

Returns: created_at (date-time), id (string), issued_by (object), issued_to (object), valid_from (date-time), valid_to (date-time)

Get API Usage

Returns the detail on API usage on a bucket of a particular time period, group by method category.

GET /storage/buckets/{bucketName}/usage/api

import com.telnyx.sdk.models.storage.buckets.usage.UsageGetApiUsageParams;
import com.telnyx.sdk.models.storage.buckets.usage.UsageGetApiUsageResponse;
import java.time.OffsetDateTime;

UsageGetApiUsageParams params = UsageGetApiUsageParams.builder()
    .bucketName("")
    .filter(UsageGetApiUsageParams.Filter.builder()
        .endTime(OffsetDateTime.parse("2019-12-27T18:11:19.117Z"))
        .startTime(OffsetDateTime.parse("2019-12-27T18:11:19.117Z"))
        .build())
    .build();
UsageGetApiUsageResponse response = client.storage().buckets().usage().getApiUsage(params);

Returns: categories (array[object]), timestamp (date-time), total (object)

Get Bucket Usage

Returns the amount of storage space and number of files a bucket takes up.

GET /storage/buckets/{bucketName}/usage/storage

import com.telnyx.sdk.models.storage.buckets.usage.UsageGetBucketUsageParams;
import com.telnyx.sdk.models.storage.buckets.usage.UsageGetBucketUsageResponse;

UsageGetBucketUsageResponse response = client.storage().buckets().usage().getBucketUsage("");

Returns: num_objects (integer), size (integer), size_kb (integer), timestamp (date-time)

Create Presigned Object URL

Returns a timed and authenticated URL to download (GET) or upload (PUT) an object. This is the equivalent to AWS S3’s “presigned” URL. Please note that Telnyx performs authentication differently from AWS S3 and you MUST NOT use the presign method of AWS s3api CLI or SDK to generate the presigned URL.

POST /storage/buckets/{bucketName}/{objectName}/presigned_url

Optional: ttl (integer)

import com.telnyx.sdk.models.storage.buckets.BucketCreatePresignedUrlParams;
import com.telnyx.sdk.models.storage.buckets.BucketCreatePresignedUrlResponse;

BucketCreatePresignedUrlParams params = BucketCreatePresignedUrlParams.builder()
    .bucketName("")
    .objectName("")
    .build();
BucketCreatePresignedUrlResponse response = client.storage().buckets().createPresignedUrl(params);

Returns: content (object)
