Before you begin

Before you run this quickstart, make sure that you or your administrators have completed the following prerequisites:

  • Make sure the Cloud Translation API is enabled in your Google Cloud project.

    Go to API library

Create an ABAP class to translate text

  1. Create a package:

    1. In ADT, go to the Project Explorer.
    2. Right-click the package ZLOCAL, and select New > ABAP Package.

    3. Enter the following details for your package:

      • Name: enter ZABAPSDK_TEST.
      • Description: enter ABAP SDK Test Package.

    4. Click Next.

    5. In the Select a Transport Request dialog, select the Create a new request checkbox.

    6. Enter a description for the transport request.

    7. Click Finish.

  2. Create an ABAP class to call the Cloud Translation API:

    1. Right-click your ABAP package and select New > ABAP Class.

    2. Enter the following details for your ABAP class:

      • Name: enter ZGOOG_CL_QS_TRANSLATION.
      • Description: enter Quick start for Translation API.

    3. Click Next.

    4. Select a transport request and click Finish.

    Replace DEMO_TRANSLATE with the client key name.

  4. Save and activate the changes.

  5. Run your application:

    1. Select the ABAP class ZGOOG_CL_QS_TRANSLATION.
    2. Click Run > Run As > ABAP Application (Console). Alternatively, press F9. If successful, the following output displays: 
      'Translation Successful'
'Translated Text is: Die Erde ist der dritte Planet von der Sonne'
