How to update Google Pay For Passes

I would like to update the data of the Google Pay for passes. Before updating, I've uploaded the sample pass with using sample code provided by Google. And now, I am trying this https://developers.google.com/pay/passes/rest. However, I don't have idea how to update the edited-code with command PUT https://walletobjects.googleapis.com/walletobjects/v1/offerClass/{resourceId}on Mac Terminal. I tried to send following commands.

 curl https://walletobjects.googleapis.com/walletobjects/v1/offerClass/{resorceID} -XPOST

 curl -X PUT 'https://walletobjects.googleapis.com/walletobjects/v1/offerClass/{resorceID}'

But it returns

<title>Error 404 (Not Found)!!1</title>
<style>

Please let me teach.

Solution

If you look at the rest methods you will see how to make the calls using python:

  headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json; charset=UTF-8'
  }
  credentials = makeOauthCredential()
  response = None

  # Define insert() REST call of target vertical
  uri = 'https://walletobjects.googleapis.com/walletobjects/v1'
  postfix = 'Class'
  path = createPath(verticalType, postfix)

  # There is no Google API for Passes Client Library for Python.
  # Authorize a http client with credential generated from Google API client library.
  ## see https://google-auth.readthedocs.io/en/latest/user-guide.html#making-authenticated-requests
  authed_session = AuthorizedSession(credentials)

  # make the POST request to make an insert(); this returns a response object
  # other methods require different http methods; for example, get() requires authed_Session.get(...)
  # check the reference API to make the right REST call
  ## https://developers.google.com/pay/passes/reference/v1/
  ## https://google-auth.readthedocs.io/en/latest/user-guide.html#making-authenticated-requests
  response = authed_session.post(
      uri+path          # REST API endpoint
      ,headers=headers  # Header; optional
      ,json=payload    # non-form-encoded Payload for POST. Check rest API for format based on method.
    )


  return response

Note there are special authorization headers for the call so just using curl may not be best but there is a [tool] (https://developers.google.com/pay/passes/support/testing) to generate authorization token for curl to work.

If you are inserting a class this url will be POST https://walletobjects.googleapis.com/walletobjects/v1/offerClass

If you are updating a class. it would be PUT https://walletobjects.googleapis.com/walletobjects/v1/offerClass/{resourceId}
