17. Get Result of Candidate in Schedule

17. Get Result of Candidate in Schedule

Definition

This  GET  API is used to fetch the status or result of a particular candidate in a schedule/ test link (such as candidate registration fields, test status, proctoring details and test results if the test is finished).

where, access-key is the unique key of the schedule/ test link from which you want to fetch the status or result of a particular candidate,
and, candidate-email-id is the unique email Id of the candidate added to a schedule/ test link for which you want to fetch the status or result.

You can get an access-key from the test link settings in your dashboard (alphanumeric key at the end of the 'Link to Share') or via API by using Create Schedule API , Get All Schedules in Assessment API or Get All Schedules in Account API.

Query Parameters

In our REST APIs, Query Parameters have to be URL encoded as the data is being transmitted in the request URL. This is especially important for the  asgn  parameter and any parameters with JSON as they always contain characters that need to be URL encoded. Since  ak  and  ts   parameters don't contain any characters that need to be URL encoded, URL encoding of these parameters can be skipped.

Mandatory parameters


Query Parameter


Description

ak

This is your Public-API-Key, which Mettl uses to identify your account.

ts

This is the current UNIX or Epoch Timestamp (the number of seconds between 1970-01-01 00:00:00 and current UTC Time). Any current generated Timestamp will be valid for 24 hours only.

asgn

This is a unique Signature which has to be generated  for each API request.

The Signature is generated by creating a String-to-Sign and hashing it with your Private-API-Key using  the HMAC-SHA256 (for version v2 and v3) or HMAC-SHA1 (for v1) hashing algorithm with Base-64 and URL encoding.
