API

The Linguapop API allows you to integrate Linguapop with your existing management software (CRM, LMS, etc.) or your website.

With it, you can create and send placement test invitations, and fetch the list of available languages

Fetch available languages

Send a GET request to:

https://app.linguapop.eu/api/actions/getLanguages

The endpoint returns a list of available languages:

Response
[
  {
    "name": "English",
    "code": "eng"
  },
  {
    "name": "Italian",
    "code": "ita"
  },
  {
    "name": "Spanish",
    "code": "spa"
  },
  {
    "name": "German",
    "code": "ger"
  },
  {
    "name": "French",
    "code": "fra"
  }
]

You should use the code property of the language when sending invitations via the API.

These codes aren't planned to change, however additional languages are planned. With this in mind, hard-coding for languages you offer is okay, as long as you keep up-to-date with new languages in case you want to offer placement tests in these languages.

Send/create an invitation to a placement test

You can create an invitation and send it to your candidate by sending a POST request to:

https://app.linguapop.eu/api/actions/sendInvitation

The request should have its Content-Type header set to application/json.

Within the request body, you should include the following:

  "externalIdentifier": "EXTERNAL_IDENTIFIER",
  "name": "CANDIDATE_NAME",

tip

You don't have to send emails!

One of the best parts of Linguapop's API integration is that you get a direct link to the placement test for each invitation you send.

Instead of sending emails, you can simply provide the candidate with this link while they are on your website, or you can even further customize your emails beyond what Linguapop provides

With Linguapop being charged only for completed tests, you will not incur additional charges by providing website visitors with a self-service placement test.

This makes Linguapop an ideal tool for acquiring high-quality leads to potential customers.

The Callback URL

Upon the completion of a placement test, Linguapop can optionally send the results of the placement test back to your software.

All you need to do to enable this is provide the callbackUrl property as part of your request body for the Send/create an invitation to a placement test request.

If a callbackUrl has been provided, Linguapop will make an HTTP POST request with a Content-Type header set to application/json, and the following body structure:

Levels used in Linguapop

Linguapop is aligned with the CEFR, displaying final results to candidates as one of the 6 main levels: A1, A2, B1, B2, C1, C2.

However, internally Linguapop tracks these levels in a more fine-grained manner, splitting the 6 main CEFR levels into 16 sub-levels:

Level name	Usually called	Level code	Lowest rating	Highest rating
A1 Low	A1.1	A1L	/	849
A1 High	A1.2	A1H	850	949
A2 Low	A2.1	A2L	950	1049
A2 High	A2.2	A2H	1050	1149
B1 Low	B1.1	B1L	1150	1249
B1 Mid-Low	B1.2	B1ML	1250	1349
B1 Mid-High	B1.3	B1MH	1350	1449
B1 High	B1.4	B1H	1450	1549
B2 Low	B2.1	B2L	1550	1649
B2 Mid-Low	B2.2	B2ML	1650	1749
B2 Mid-High	B2.3	B2MH	1750	1849
B2 High	B2.4	B2H	1850	1949
C1 Low	C1.1	C1L	1950	2049
C1 High	C1.2	C1H	2050	2149
C2 Low	C2.1	C2L	2150	2249
C2 High	C2.2	C2H	2250	/

You can use this table together with the rating result to create graphical representations of the candidate's rating within your own software.
