This article explains the reason why you see the following message in Postman:
Your trial ends in … days. Upgrade your plan to continue collaborating with everyone on your team and get significantly more resources.
What is the 14-day Basic plan trial?
Since the Free plan allows only 3 team members, a trial of the Basic plan has been started to let all invited members join your team. Take a look at our pricing page to see what the Basic plan allows you to do.
Why do I see the message "your trial ends in ... days"
Currently, collaboration on the Postman Free plan is available for up to 3 users. Note: Any pending invite (an invite sent to a user that hasn't yet been accepted) will take a user slot. You'll be able to see your pending invites on the Members and groups page under Suggestions.
Inviting a 4th user unlocks the 14-day trial. The message indicating that your trial ends in a certain amount of days is triggered as soon as an invite is sent to a 4th user to join your Postman team.
What should I do when the trial ends?
At the end of your trial, you can either upgrade or keep your team up to 3 members to stay on the Free plan.
