As an assessment provider, you want to reduce the friction for your customers to order assessments for their candidates. By building on top of Kombo’s Unified ATS-Assessment API, you can allow your customers to seamlessly start assessments right from their Applicant Tracking System (ATS). Here’s how it works:
  1. You submit your available assessment packages to Kombo. We’ll take care of configuring them in your customer’s integration. Your customers can now submit assessment orders from their ATS.
  2. When your customer triggers a new assessment order in the ATS, Kombo sends you a webhook event, so you can automatically send out an email and get the assessment process started.
  3. Once the candidate has completed the assessment, you send the results to Kombo. We then write them to the ATS system.
  4. Your customers can conveniently access the assessment results directly within their ATS.

​
1. Configuring available packages

Submit all your available assessment packages for the customer to Kombo. Kombo automatically configures the ATS to surface the assessment packages to your customer. 
curl --location --request PUT 'https://api.kombo.dev/v1/assessment/packages' \
  --header 'X-Integration-Id: smartrecruiters:example_integration_id' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer example_kombo_token' \
  --data '{
    "packages": [
      {
        "id": "YOUR-PKG-ID-0001",
        "name": "Postgres",
        "type": "SKILLS_TEST",
        "description": "Postgres test description..."
      },
      {
        "id": "YOUR-PKG-ID-0002",
        "name": "Javascript",
        "type": "SKILLS_TEST",
        "description": "Javascript test description..."
      }
      {
        "id": "YOUR-PKG-ID-0003",
        "name": "Civil Records",
        "type": "BACKGROUND_CHECK",
        "description": "Civil records background check description..."
      }
    ]
  }'
Your customer will then be able to view your submitted tests in their ATS:

2. Reacting to new assessment orders

Please refer to this guide for reacting to new inline assessment orders.
Your customer triggers an assessment for a specific candidate from their ATS. Kombo will then notify you that a new assessment order has been created. You should then send out your assessment (through an email, for example) to the candidate to be assessed. The candidate will then complete your assessment.
assessment:order-received
{
  "id": "9N4VDpgwJPwnMMssyPKRnM58",
  "type": "assessment:order-received",
  "data": {
    "id": "B5KQKhAgTv6ZwzrfAbqbhipd",
    "integration_id": "workday:CBNMt7dSNCzBdnRTx87dev4E",
    "package_id": "typescript_test",
    "status": "OPEN",
    "candidate": {
      "email": "john.doe@gmail.com",
      "first_name": "John",
      "last_name": "Doe",
      "phone": "+1 123 456 7890",
      "remote_id": "26vafvWSRmbhNcxJYqjCzuJg"
    },
    "application": {
      "remote_id": "HAQ9uCfC1zi3TLbB1n5cyHgP"
    },
    "job": {
      "remote_id": "A1KQKhAgTv6ZwzrfAbqbhcde",
      "name": "Engineering Manager",
      "location": {
        "city": "Berlin",
        "country": "DE",
        "raw": "Berlin, Germany",
        "state": "Berlin",
        "street_1": "Lohmühlenstraße 65",
        "street_2": null,
        "zip_code": "12435"
      },
      "hiring_team": [
        {
          "first_name": "Jane",
          "last_name": "Doe",
          "remote_id": "26vafvWSRmbhNcxJYqjCzuJr",
          "email": "jane.doe@gmail.com",
          "hiring_team_roles": [
            "RECRUITER"
          ]
        }
      ]
    },
    "remote_data": {
      "upstream_webhook_body": {},
      "/assessment-orders": {}
    }
  }
}
remote_data will contain the exact payload received from the customer’s webhook.
You can reject your customer’s order of a package by responding with 422 status code and body in the following shape: 
HTTP/1.1 422 Unprocessable Content
Date: Fri, 28 Jun 2024 12:00:00 GMT
Content-Type: application/json; charset=utf-8
Content-Length: 187

{
  "status": "ORDER_REJECTED",
  "message": "There is an existing order for this candidate..."
}
We will then also display the message in the UI of the ATS so that your user knows what’s going on.
The response to the assessment:order-received webhook’s body needs to match the shape described in the example to make us to reject the assessment order!Other errors will not cause us to reject the assessment. We will still accept it and make it available via the Get open orders endpoint so that you can retry at a later point.

3. Writing back results

Once the candidate has completed your assessment, you send the results of the assessment to Kombo: 
curl --location --request PUT 'https://api.kombo.dev/v1/assessment/orders/B5KQKhAgTv6ZwzrfAbqbhipd/result' \
  --header 'X-Integration-Id: smartrecruiters:example_integration_id' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer example_kombo_token' \
  --data '{
    "status": "COMPLETE",
    "score": 90,
    "max_score": 100,
    "result_url": "https://example.com",
    "completed_at": "2023-04-04T00:00:00.000Z",
    "attributes": [
      {
        "type": "TEXT",
        "label": "Role fit",
        "value": "Excellent"
      },
      {
        "type": "SUB_RESULT",
        "id": "<YOUR_INTERNAL_ID_OF_THE_TEST>",
        "label": "Personality test",
        "score": {
          "value": 97,
          "max": 100
        },
        "status": "COMPLETED"
      }
    ]
  }'
Kombo will write the assessment results back into your customer’s ATS system. Your customer can then view the assessment results directly in their ATS.
