Attaching a new Templates to an existing Project using API calls

[valeSouza]

I can't find any doc about this subject that could bring me a solution, then here I'm:

I already created many projects using API calls, via Snaplogic and even updated them in the same way, but what doesn't work is the action attachTemplate as below:

this was supposed to add a new Template to a existing project, but when I use PUT passing the update parameters it returns error code 422.

We're doing this via Fusion, but I think the same approach applies.  We're using "assignCategories".

Just a heads up, I remember we originally wrote this with a different call and it removed existing templates from the projects.

Hi,

I just tried to do it using a PUT call and it worked:

https://example.my.workfront.com/attask/api-internal/PROJ/attachTemplate?method=PUT&action=attachTem...

using the following payload:

{
  "templateID": "<templateID>",
  "predecessorTaskID": "<predecessorTaskID>",
  "parentTaskID": '',
  "excludeTemplateTaskIDs": [
    "<excludeTemplateTaskID>"
  ],
  "options": []
}

Regards

Lars

Hello @lgaertner, do you know what I should enter in "options" in the payload if I only need to select 'Queue Properties & Issue Setup'? (see image below)
