Room For Improvement

IBM API Connect requires improvements in integration, usability, scalability, support, monetization, documentation, flexibility, and cost-effectiveness across environments.
Postman Enterprise users request improved documentation, UI, integrations, automation, and pricing, while addressing compatibility, speed, and testing challenges.
Examples include the lack of connectivity to MQ.
Software Engineer IV at Royal Cyber Inc.
You need to know when traffic peaks, so use auto-scaling when traffic comes.
Works at a outsourcing company with 5,001-10,000 employees
Connectivity to MQ is not available in IBM API Connect.
Software Engineer IV at a financial services firm with 1,001-5,000 employees
One of the primary challenges with Postman is handling authentication issues, especially relating to tokens and passwords.
Senior developer at Digital world advisory
If they can enhance it to have a database kind of validation like we have in ReadyAPI, it would be better.
Automation Architect at Cognizant
Maybe Postman can be a good contender and replicate some features such as more scripting and control over API calls.
Senior QA Manager at a tech services company with 11-50 employees

Have addressed performance challenges while benefiting from flexible subscription models and reliable user access
To improve IBM API Connect, based on customer experience, you could work on latency. You can increase scalability and availability. If you're connecting with any other cloud, it connects to the infrastructure which needs to be managed with the customers and cloud providers, so if you have a setup, we can handle it easily. I have faced latency issues on the server, related to our management. If you need to stabilize your server based on peak traffic, you need to configure the scalability model. You need to know when traffic peaks, so use auto-scaling when traffic comes. If the application is not in use, the value should be zero, and it starts from zero. Based on customer experience, the value will increase, and when there is no customer servicing, the peak would be reduced, making the value remain zero. Following this approach, you should be able to optimize costs and satisfy customer experience.

Automated testing optimizes API workflow and collaboration
Since I am using the free tier, one improvement would be to increase the number of requests you can send in a short time period. Currently, if I send 200-300 requests in a short period, Postman Enterprise requires a 30-second wait before sending another bundle of requests unless you upgrade to a higher tier. Secondly, Postman Enterprise sometimes takes several minutes to load the whole workspace. With 2,000-3,000 requests in a workspace, it can take a minute or two to load all requests. When creating a new workspace and moving requests between workspaces, depending on internet speed, it can take a longer period to copy those requests or workspace from one place to another.
