Hi team, can we edit any project using free jira account through postman or any integration tool?

Question

I'm trying to edit the project that i have created in Jira Cloud platform through postman 
and my integration tool 
As I'm using free account it is showing an error
{    "errorMessages": [        "Changing permission schemes is not allowed on the Jira Software or Core Free plans."    ],    "errors": {}}
Is there any way I could edit projects in free jira account with postman

Good inclusion of this bug - that's totally not obvious!

While it is not possible to set permission on a Free plan (neither UI nor through API) one might say that updating a project's description should work, indeed.

Assuming you just wanted to set the project's description, you'll be running into the following:
https://jira.atlassian.com/browse/JRACLOUD-74569

If so, you could upvote the linked bug - otherwise you would need to upgrade your Plan to, at least, a Standard plan - according to the limitations listed here for the "Free" Plan:

@Soumya Mariyala - Yes, but it's not possible to modify a project's permission schemes via the API or manually via the UI.
