Welcome to the Protogrid Developer Wiki. A place to gather all the documentation and tips&tricks regarding Protogrid.

JSON API Authentication

At the moment only Basic Authentication is supported. If you need OAuth2 please contact us at protogrid-support@protogrid.com. All http requests require an authentication. If the authentication fails, an error will be returned. The error describes whether a HTTP Header field is missing or the login data is incorrect.

How to authenticate

A POST http request to the API endpoint “/api/v2/authenticate” does log in the user and the response contains the set-cookie header with the generated cookie. HTTP header fields:

<user_id> [required]: The user_id corresponds to the username or e-mail address of the user.
Either <user_email> or <user_id> have to be specified.
<user_email> [required]: The user_email corresponds to the e-mail address of the user.
Either <user_email> or <user_id> have to be specified.
<user_secret> [required]: The user_secret corresponds to the password of the user.


Request HTTP

Example request:


Request header:

  POST /api/v2/authenticate
  Host: your_environment.protogrid.com
  user_id: example_user
  user_secret: example_secret
Request jQuery

Example in jQuery:

  url: 'https://example.protogrid.com/api/v2/authenticate',
  contentType: 'application/json; charset=utf-8',
  dataType: 'json',
  beforeSend: function(xhr){
Request Python

Example in Python (with requests):

url = "https://example.protogrid.com/api/v2/authenticate"
headers = dict(user_id="test_user@testdomain.com", user_secret="test_password")
req = requests.post(url, headers=headers)
response = req.text
response = json.loads(response)
cookie = req.cookies['session']
Success Response

Example response of successful authentication:

  "errors": [],
  "protogrid_environment_version": "1.3.9",
  "result": "Login successful!"
Unsuccessful Response

Example response of unsuccessful authentication:

  “errors”: [
      “code”: 401,
      “message”: “Your login wasn’t recognized. Please check your e-mail
      address and password.”
  "protogrid_environment_version": "1.3.9",
  “result”: {}

How to send authenticated http requests

Each request to any API endpoint has to be authenticated using the cookie returned by the /api/v2/authenticate API endpoint.



Example ajax request: Note that when jQuery runs in a browser, that the cookie is passed automatically with the request.

  type: 'GET',
  url: 'https://example.protogrid.com/api/v2/apps',
  contentType: 'application/json; charset=utf-8',
  dataType: 'json',
  success: function(data) {
  error: function(data) { console.log(data); }

Note: Some browsers handle cookies differently. For more information, see the browser specific documentation.

Example Python

Example Python request:

# The cookie variable was set above in the authenticate example.
url = "https://example.protogrid.com/api/v2/apps"
req = requests.get(url, cookies=cookie)
response = req.text
response = json.loads(response)

Note: For more information about the requests, please refer to http://docs.python-requests.org/en/master/
