HttpRequest req = new HttpRequest();
req.setEndpoint('callout:Research_Guardian/equipments');
req.setMethod('GET');
HttpResponse response = new Http().send(req);
if (response.getStatusCode() == 200) {
String responseBody = response.getBody();
System.debug('Available Equipments: ' + responseBody);

Challenge Not yet complete... here's what's wrong: We can't find the appropriate access to the authentication tokens.

Ops bad - In video expressions are wrong in custom header {!$Credential.Secure_Research.client_id} {!$Credential.Secure_Research.client_secret} in video expression are encode in quotes like '{!$Credential.Secure_Research.client_secret}' which is wrong. Please update your custom header and try.

use these {!$Credential.Secure_Research.client_id} and {!$Credential.Secure_Research.client_secret} instead fo hard ones on the headers.
