Install Agent Designer if it is missing

This is a quick tip about the Agent Designer I wrote earlier about.

The Agent Designer is part of the 27.4 monthly update. Existing sandboxes upgraded to v27.4 or higher will automatically receive the Agent Designer. Production environments will not get the Agent Designer.

But what if you want to test the Agent Designer in a copy of a production environment? That makes a lot of sense, of course, testing on fresh data.

Pre v27.4 environments

If the production environment is at v27.3 or lower, copy it to a sandbox and upgrade to v27.4 or higher.

Post v27.4 environments

However, if the production environment is already upgraded to v27.4 or higher, a copy of that production environment to a sandbox will not install the Agent Designer for you. So, how to fix that?

I haven’t seen any official documentation on how to install the Agent Designer in a sandbox environment if it isn’t installed. But luckily, there is an easy way to do this.

The app ID of the Agent Designer is: 00155c68-8cdd-4d60-a451-2034ad094223

Now the only thing you have to do is to use the install from AppSource URL:

https://businesscentral.dynamics.com/[tenantid]/?noSignUpCheck=1&page=2503&filter="ID" IS '[appid]'

In the URL below, make sure to replace the tenantid parameter with the target

https://businesscentral.dynamics.com/[tenantid]/?noSignUpCheck=1&page=2503&filter="ID" IS '00155c68-8cdd-4d60-a451-2034ad094223'

That’s it, good luck with designing agents in Business Central!
