I completed the "Prepare for Your Administrator Certification Exam (CRT101)" course on August 10–11, 2026, and I still haven't received my certification voucher via email. What should I do?

Hello,
I have a question: if I book an exam A using a voucher, but then I have to cancel the exam and would like to book an exam B using that voucher, can I do it? Or can I no longer use the voucher even if I canceled exam A?
Thanks.
Hi, For general policies and processes, visit the Salesforce Exam Reschedule and Cancellation Policy. If you cancel an exam for which you used an exam voucher as payment, the exam voucher will be restored. If your exam voucher has not expired, you can reuse the exam voucher code to reschedule an exam.

I am currently MCD-Integration and API Associate. My immediate goal is to take more certifications. I am eyeing MCD-Integration Professional, API Design Associate, or/and Architect Specifications.
The biggest challenge I face is the lack of documentation. The primary resource I find are instructor led courses that cost a decent amount of money.
Is there a way to study for these exams without going through instructors? Are there recommended books or materials?
@mulsoft "Mule in Action 2nd edition" is quite an old and not relevant after Mule 3.6 which has phenomenal changes in components like http, database, splitters, flows, processing-strategies,exception, message structure, mel expression and almost everything in Mule and ESB which is a API driven in today's world.
It was one of the great book though in early 2012-2016 period of time covering almost everything and I would not suggest anyone to go through that with today's Mule 3.7+ to Mule 4 .
It would have been great if the author would had brought a new edition of that book say part 3 to cover the latest Mule feature, but on a discussion with the author (who is also a good friend of mine), there is very less chance he could bring that :)
Hi,
Currently doing the Mule.U ESB Developer Essentials online course.
I'm now on week 5 and everything is working perfectly except for the debug mode. I can't enter in debug mode.
Whenever I run the application in debug mode it loads but the "Mule Debugger" window says:
"Mule Debugger is nor running. Launch your Mule application in debug mode".
At first I thought it could be some sort of CE vs EE feature and that not even in the studio I could use this feature. However I recently confirmed that the Mule application is set to the Target Runtime Engine : "Mule Server 3.6.1 EE"
Can you please help me?
Br,
Was facing the same issue after upgrading to Version: 7.23.0
Right clicking the Project -> Properties -> On Mule Project changed Server Runtime from 4.9.11 to 4.10.1, accepted the dialogs (Anypoint crashed the first time, so I repeated the steps, second time worked).
After that right click the Project again -> Debug As... -> Debug Configurations on Target Server Runtime, select the same version 4.10.1.
Restarted Anypoint studio and debugger worked now.
They really need to up their support docs with better instructions, hope this helps.

As per stack trace you are trying to call java component with ReflectionEntryPointResolver. But no arguments passed. For mapping arguments please refer
For more details refer -
https://docs.mulesoft.com/mule-user-guide/v/3.8/entry-point-resolver-configuration-reference
Cant comment more unless mule configuration is shared. Hope this helps.
Hi,
I import another Mule application called templates into my local .m2
After that, could you please provide me the steps how the main mule flow(implementation) can refer to the flows in the template?
I googled, but failed.
Thanks
Because it says you need to import it, I thought it must have existed somewhere. Why did they not hint that you need to create it rather than import it. Oh well thanks.

Try the following example here :-

<http:request-config name="HTTP_Request_Configuration" host="mu.mulesoft-training.com" port="80" basePath="/essentials/united/flights" doc:name="HTTP Request Configuration"/>

Now, if you hit the url :- http://localhost:8081/united it will wok fine as you can see in the following screenshots :-
One of my colleagues downloaded the Anypoint Studio trial a couple of weeks before the course began, and now it has expired so he can't complete the course. The rest of us will face this problem in a couple of weeks time as well, as the course lasts longer than 30 days. Can we extend our trial periods?
@alejandro.dobniewski Yup realised that lately ..
Not sure but maybe for getting a fresh licence or commercial account sales team can help. Correct me if that's not right.
Anyways here is the doc I found:-
