Submitting a form with an file attachment

In this example, we demonstrate how to submit a form that includes a file attachment using the OneEntry API.

✅ Purpose of the scenario:
  • Get form configuration from OneEntry Platform
  • The user fills out a form (e.g. response, feedback).
  • Attaches a file (image, resume, document).
  • The data and file are stored together in FormData
  • Submit the collected data to an OneEntry API.
✅ What you need:
  • A valid PROJECT_URL and APP_TOKEN for authentication with the OneEntry API.
  • Form in OneEntry with a field of type "File" (type file)
  • Form marker (eg resume_form)
📌 Important:
  • These examples do not include error handling.
  • You can manage errors using a try-catch block or by employing a construction like await Promise.catch((error) => error).
