The root URL
To find your application's Workflow API root URL, go to Settings - API.
As soon as you have activated the Workflow API Bubble will reveal the root URL.
Constructing the complete URL
Keep in mind that each branch in your app (including custom branches) have a separate root URL. The Main branch always has the ID version-test. Remember to update the external call to reflect which branch you want to send the request to.
The complete endpoint URL consists of the root URL combined with the name of the Workflow you want to access.
For example, the URL of the API Workflow in the image above would be:
