Hi,

I want to return in the same call, the task and subtask. Because I have more than 1000 task so the call: {{baseUrl}}/tasks/:task\_gid/subtasks? but I try to do with the call of projects because it is more quickly ant effective for my job.

How it is posible? this call not return the subtask  
/projects/project\_gid/tasks?opt\_expand=custom\_fields,subtask  
this return the task but not the subtask  
Thanks

Hi @anon16089076,

You can’t, unfortunately - you have to retrieve the subtasks separately. The API team has explained to us that this is for performance reasons - something along the lines that asking for a set of tasks and all of their subtasks in one call can potentially return too big of a data set for the API to handle reliably.

Thanks, so I have to do:

1. One call for the task.
2. And other call with the subsktask, and if my substask have sub - subtasks, in this call i can give the information of the sub-substask or i have to do other call for the information.

Thanks
