Create a new user and a user group
Go to User Management
Create new user for Screenful (using an email address that you own)
Create an "integrations" usergroup (no permissions to start).
Assign Screenful user as a member of the integrations group
Grant Jira access for the user group
Select Applications from the Jira Administration menu on top right corner
Select Application access from the left menu
Click on Add group and then grant access.
Now the newly created user can log in but cannot see or access any projects in Jira. To grant visibility to projects, you now need to assign the group to each of the projects that the user needs to see.
Assign the user group to a project
Click on Projects
Select the project by clicking the name
Select Users and roles from the left side menu
Add user group to a role by assigning Group to Role on project menu
Make sure that the selected permission scheme for the project allows Project Role to Browse projects.
Note that the Permission Scheme, while global, is being applied to this project specifically. Giving the user "browse on projects" will only apply to projects on which they have been assigned a role (see 2 above). So this new user can only in fact browse this specific project.
Repeat with all the projects included in the agile board
The filter query associated with an agile board defines which projects are used as a source for issues to be included in the board. In order to see all the issues, the user must have access to all those projects. Therefore, you need to look at the filter query and repeat step 3 (Assign group to a project) with all the projects included in the query.
That's it! You can test this now by logging in as Screenful user. You should be able to access the project and its issues.
If you're using self-hosted Jira, you also need to make sure that the Jira API is accessible from outside your network.
I've done the step above but still can't access the tasks in the board?
Please check your board filter settings.
