question

Here is the code in Kotlin:

@Test fun telnyxSendSmsTest() {

     val telnyxNumber = "+12702008692"
     val telnyxApiKey = "KEY0182A10DC8EBE12F39CDF6C3B3DA1466_9bGXhFiOTB2x1f12u7a8dP"
     val toPhone = "+6156528352"
     val messageContext = "Something"

     val defaultClient : ApiClient = Configuration.getDefaultApiClient()
     defaultClient.basePath = "https://api.telnyx.com/v2"

     // Configure HTTP bearer authorization: bearerAuth
     val bearerAuth = defaultClient.getAuthentication("bearerAuth") as HttpBearerAuth
     bearerAuth.bearerToken = telnyxApiKey

     val apiInstance = MessagesApi(defaultClient)
     // CreateMessageRequest | Message payload
     val createMessageRequest = CreateMessageRequest()
         .from(telnyxNumber)
         .to(toPhone)
         .text(messageContext)
     try {
         val telnyxResponse = apiInstance.createMessage(createMessageRequest)
         assertNotNull(telnyxResponse)
     } catch (e: Exception) {
         System.err.println("Exception when calling MessagesApi#createMessage");
         e.printStackTrace();
     }
 }

And this is the maven dependency I've used:

    <dependency>
         <groupId>com.telnyx.sdk</groupId>
         <artifactId>telnyx</artifactId>
         <version>2.8.0</version>
         <scope>compile</scope>
     </dependency>

Here the code in Kotlin:

 @Test
 fun telnyxSendSmsTest() {

     val telnyxNumber = "+12702008692"
     val telnyxApiKey = "KEY0182A10DC8EBE12F39CDF6C3B3DA1466_9bGXhFiOTB2x1f12u7a8dP"
     val toPhone = "+6156528352"
     val messageContext = "Something"

     val defaultClient : ApiClient = Configuration.getDefaultApiClient()
     defaultClient.basePath = "https://api.telnyx.com/v2"

     // Configure HTTP bearer authorization: bearerAuth
     val bearerAuth = defaultClient.getAuthentication("bearerAuth") as HttpBearerAuth
     bearerAuth.bearerToken = telnyxApiKey

     val apiInstance = MessagesApi(defaultClient)
     // CreateMessageRequest | Message payload
     val createMessageRequest = CreateMessageRequest()
         .from(telnyxNumber)
         .to(toPhone)
         .text(messageContext)
     try {
         val telnyxResponse = apiInstance.createMessage(createMessageRequest)
         assertNotNull(telnyxResponse)
     } catch (e: Exception) {
         System.err.println("Exception when calling MessagesApi#createMessage");
         e.printStackTrace();
     }
 }

Hey there!

I think there might be some bad pathing/nesting in the create request. Can you try running this in Kotlin and see if it works on your end?
