Hi @Geaux Design 

Good question.

Please post screenshots with how your Zap steps are configured along with the encountered error in order for us to have context, thanks.

You’ll likely have to create 1 To Do for each.

You can use Looping to create multiple To Dos in less steps, but not less Tasks.

Step 1 : Trigger on new status in Dubsado

Step 2: 

Step 3: Create a Todo list in Basecamp. At this point, the test is returning without an error. 

Step 4: Create (Add) a Todo in Basecamp 2 inside the Todo list I just created. This is where the error gets thrown. The red circle is Grammerly not liking the spelling. 

Thanks so much for your help.

Map the returned To Do List ID from the previous step.

Thank you. I did just that making sure the spacing and lettering was identical. Below is the Zap error I got running a test.

Do you think I need to add a delay? Like make it wait one minute and then try to add the todo?

I appreciate your expertise very much.

@Troy Tessalone you are a genius!  Thank you from the bottom of my heart. If there is a send a coffee program in Zapier, let me know so I can show my appreciation. 

To leave a visual breadcrumb for anyone in the future. 

Under the Todo List, select from the “Create Todo List in Basecamp 2” the “ID”
