Hey guys, I would like to know if is possible respond an approval task from my sharepoint list or document library directly instead of receiving an email? I mean is great receive an email with the link to approve a task but also if someone, an approv

Or you could use the Common property in the workflow "Approval URL" and then write that value to a column in your list/library and provision a link directly to the approval task.

Afraid I only have access to O365 at the moment, so the Common:ApprovalURL property is not available to me (not that I'm aware of anyway, I've only just started using O365 workflow).

On-prem you could do it a couple of ways.

I would create one field call ApprovalURL (single line of text) and use an Update Item action to add the Common:ApprovalURL property. This will write the URL straight to the field, then to tidy it up so to your Library Settings and create a Calculated Column with the following configuration

Be sure to select anything other than Single line of text for how the data type is returned and SharePoint will render the HTML.

What type of workflow is this? List or site?

ApprovalURL is available only within the task action, it doesn't make sense outside of it.

what kind of task do you use? that might cause how difficult it might be to determine approval url.

I personally don't think it's a good idea to make approval link available directly within the list. apart from  difficulties to get it there, it will be available to all the users accessing the list but only one/few of them will have rights to answer. which might confuse people.

if your users lose approval links/mails there is probably a better solution to give them access to 'My workflow tasks' webpart where they can see their all tasks from all workflows.

if you learn them to check the page with their tasks regularly you might save a lot of effort and troubles with approval links.
