Set up a Translation System with Contentstack Webhooks and Workflows, AWS Lambda, and AWS Translate

While Contentstack does not offer translation services, it offers easy integration with third-party translation providers. In this guide, we will learn how to set up a translation system using Contentstack's webhook and workflows along with AWS Lambda and AWS Translate.

Here's a quick overview of the process: When the workflow stage of entry in the master locale changes to "Send to Translation", a webhook is triggered, which invokes an AWS Lambda code. This code translates content using AWS Translate and then localizes the entry with the translated content using a Content Management API request. This also changes the workflow stage status of the entry to "Review Translation.

Here are the steps to set up this translation solution:

  1. Set up the essentials
  2. Set up workflows for translation
  3. Set up Lambda function for translation
  4. Trigger a webhook to initiate translation


  • Working knowledge of AWS API Gateways
  • Access to the AWS environments such as AWS Lambda, AWS API Gateway, and AWS IAM
  • Contentstack account
  1. Set up the Essentials

    First, create a stack, and add a content type (in our example it is Product), add entries to it, at least one additional language, and a publishing environment.

    Once you have these configured, then you're ready to begin the integration process for translation.

  2. Set up Workflows for Translation

    To set up workflows for the translation process within Contentstack, follow the below steps:

    1. Create a workflow by hovering over the “settings” gear icon and clicking on Workflows
    2. Click on Add Workflow
    3. Add stages, as required. Add a translation-related stage, such as Send to Translation.

    Once the editor changes the workflow stage to “Send to Translation,” the webhook will be triggered and call the AWS Lambda function.

  3. Set up Lambda Function for Translation

    Perform the following steps to set up your AWS Lambda function:

    1. Login to your AWS Management Console, select AWS Lambda Service from the service list.
    2. Click on the Create Function button, and then the Author from Scratch option.
    3. Configure the lambda based on your requirements. Choose Node.js as your run-time language.

      Note: You can use any language instead of Node.js. You can also add triggers to your lambda to push an event to SNS when the lambda is invoked.

    4. AWS Lambda offers an inline code editor. You can write your lambda code here or alternatively upload the code. For our example, we will upload the code due to the large size.

      Download the code

    5. In the Environment variables section, enter the credentials against the variables as follows:

    6. In the Lambda function handler and role, keep index.handler as Handler and for the Role choose an existing role or create a new role from template(s).
    7. Review your setting and click on the Create Function option if everything you entered is correct.

    Once you do this setup, AWS Lambda will run the code that we have uploaded and translate the English content into French and will deliver the translated content to your content type. The workflow stage of the translated entry also changes to Ready for Review.

  4. Trigger a Webhook to Initiate Translation

    We will now set up a webhook that triggers when the entry workflow stage is set to Send to Translation. To do this, log in to your Contentstack account and perform the following steps:

    1. Hover over the “settings” gear icon and click on Webhooks
    2. Click on + New Webhook
    3. Enter any valid name for your webhook, for example, AWS Lambda For Translation.
    4. In the URL to notify field, enter the AWS Lambda URL, where the webhook will notify about the change.
    5. Inside Custom headers, provide the details as shown below:

    6. Under the When section, select the options Any > Entry > All > Workflow Stage Changed > (Workflow name) > (Stage name for example, "Send to Translation").

This will configure your webhook to trigger on a workflow stage change such as “Send to Translation,” like in the above workflow example. As soon as the webhook is triggered, it notifies the specified URL about the event along with a JSON payload.

Additional Resource: Thought we don't provide translation, we do provide the ability to integrate with third-party translation providers that will translate content for you. All you need to do is make use of Contentstack workflows and set up a webhook trigger to initiate the translation process. Use any popular translation tool, such as Worldserver and iLangl, to translate your content. Here's our Manage Content Translation in Contentstack guide that gives a detailed explanation of how you can do all of this.
