Translate text

This quickstart shows you how to create a program that translates text from English to German by using the Cloud Translation API v2.

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 a program to translate text

  1. In the SAP system, create an executable program in your custom namespace (for example, Z or Y) by using transaction SE38.

    1. In the SAP GUI, enter transaction code SE38.

    2. In the Program field, enter a name of your program, for example, ZDEMO_TRANSLATE.

    3. Click Create.

    4. Specify the program attributes:

      1. In the Title field, enter a title of your program, for example, Translate from English to German.

      2. In the Type field, choose Executable Program.

      3. Click Save.

      Replace DEMO_TRANSLATE with the client key name.

  2. Run your application in SE38. If successful, the following output displays: 

    'Translation Successful'
'Translated Text is: Die Erde ist der dritte Planet von der Sonne'
