You are experiencing one of the following issues
I receive the “You’ve exhausted all available runs” error when I run a Postman collection.
What to expect
Postman limits collection runs to 25 per user per month for users on a Basic, and grandfathered Professional and Enterprise Plans.
Performance test run limits are 25 runs for users on a Basic Plan and 250 for users on grandfathered Professional and Enterprise plans.
To get unlimited collection runs, upgrade to a Solo, Team or Enterprise Plan or if you are on a grandfathered Basic or Professional Plan purchase the collection runner add-on. Note: To get unlimited Performance Runs you will need to move to a new Free, Solo, Team or Enterprise Plan.
Unblock yourself
You can purchase the collection run add-on by selecting Purchase add-on and selecting Subscription in your Postman dashboard.
Note: This add-on is only available on Basic and grandfathered Professional and Enterprise Plans
To upgrade your plan to get additional performance test runs, open your billing dashboard and select Upgrade or Edit plan.
