Assessment Callbacks

When an assessment is completed we will send an immediate callback to the URL nominated for your organistation during setup.

The callback content is the finished assessment record encrypted as a JSON Web Token.

Content: 

{"jwt":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhc3Nlc3NtZW50Ijp7InRva2VuIjoiWXlURDVMSmNFa0NjYVNyTjVIdFoyem1LIiwic3RhZ2UiOiJVbnJlZmxlY3RpdmVBY3Rpb24iLCJyYXRpbmciOiJTaWx2ZXIiLCJjb21wbGV0ZWRfYXQiOiIyMDE3LTAzLTAzIDAzOjI3OjAyIFVUQyIsImNyZWF0ZWRfYXQiOiIyMDE3LTAzLTAzIDAzOjI2OjI4IFVUQyIsInVwZGF0ZWRfYXQiOiIyMDE3LTAzLTAzIDAzOjI3OjAyIFVUQyIsIm9yZ2FuaXNhdGlvbl9jcmVkaXRfYmFsYW5jZSI6OTk5OTk5MX19.iv6auvL7pRzSHcUcLV0I3Z_caAllVSxLQG16l0KDrX4"}

The JSON Web Token can be validated using your Access Token and the HS256 algorithm.

Sample Ruby Code:

# using https://github.com/jwt/ruby-jwt
require 'jwt'
JWT.decode(params[:jwt], ENV['API_KEY'], true, { algorithm: 'HS256' })
=>[{"assessment":{"token":"qRddQPQ8oQTohTxxh4fXSTXC","stage":null,"rating":"N/A","probability":"23%","completed_at":"2025-10-29T12:35:26.181Z","created_at":"2025-10-29T00:00:00.000Z","updated_at":"2025-10-29T00:00:00.000Z","organisation_credit_balance":1,"creator":{"email":"example@example.com","first_name":"George","surname":"Jungle"},"jobseeker_id":"10000001","jobseeker_name":"Jane","scores":{"total_matrix_points":23},"site":{"name":"Sydney"},"assessment_type":{"name":"Type"},"status":"Completed","exercise":null,"exercises":[{"name":"HIGHLY LIKELY TO SUCCEED","path":"/exercise/xxxExamplexxx","answers_url":null,"percentage_completed":0,"completed_at":null,"due_on":"2025-12-10","motivation":"Doing this will make you a better person."}]}},{"alg":"HS256"}]
