We deprecated our legacy API at the end of Q2 2025. To support this change, we’ve created a migration guide to help you update your integration. It includes example requests, responses and the steps needed to migrate. If you’re currently using the legacy API, please read this migration guide to ensure continued functionality. See the API reference for the current endpoints.

Updating your request header

     --header 'X-Api-Key: <APIKEY>' \
     --header 'Content-Type: application/json' \

Key differences

  • Base URL: https://api.beyondwords.io/v1 (replaces https://app.beyondwords.io/api/v4)
  • Authentication: X-Api-Key (replaces Authorization header)

Example requests

     --url https://api.beyondwords.io/v1/projects/{project_id}/content \
     --header 'X-Api-Key: <APIKEY>' \
     --header 'Content-Type: application/json' \
     --data '
{
  "type": "auto_segment",
  "title": "<h1>Title</h1>",
  "body": "<p>Example body text.</p>",
  "source_id": "<articleId>"
}'
These examples compare requests made using the legacy API’s create endpoint with those using the new API’s create endpoint.

}
This is not a full response. It has been shortened to highlight the main differences. For more details on what a full response looks like, please visit our documentation.

​
Key differences

In the legacy API response, the returned ID is a numeric “podcast” id , which will no longer be used. In contrast, the new API returns a string content_id, which will remain the standard identifier moving forward. While setting a source_id when creating content is optional, doing so eliminates the need to store the content_id from the response. Without a source_id, you may need to save the content_id separately to embed the player. By setting the source_id as the article ID you may have already set, you can easily use this to embed the BeyondWords player without additional data handling.

​
Migration steps

1

Update the base URL

  • Change all API requests from: https://app.beyondwords.io/api/v4
2

Update request header method

  • Legacy API: Uses the Authorization header with the API key.
  • New API: Requires the X-Api-Key header with the API key.
  • Note: The API key value itself remains the same
3

Update endpoints

Replace old API endpoints with the new ones:
  • Legacy API: /projects/{project_id}/audio
  • New API: /projects/{project_id}/content — see Create and generate content
  • Also update: Any other endpoints you’re using
4

Handle ID changes

  • Legacy API: Returns a numeric “podcast” id (deprecated).
  • New API: Returns a string-based UUID “content” id.
  • Action required: Update any code that expects or processes the ID
5

Use source_id for easier integration

  • Change field name from external_id to source_id in your requests
  • Setting a source_id when creating content is optional but recommended
  • If you set source_id to match your existing article ID, you can use it to embed the BeyondWords player without needing to store the content_id from the response
6

Update Content Format (Optional)

  • Consider using HTML formatting for title and body content
  • Example: "title": "<h1>Title</h1>" instead of "title": "Title"
  • This provides better control over how content is processed

​
FAQ

Yes, your API key will continue to work. Only the header name and endpoints are changing.
After Q2 2025, the legacy API will be shut down and any applications using it will receive errors.
Yes, both APIs will be available until the deprecation date to allow for a smooth transition.
