Top Con

Insecure off-premise storage

To properly use this with full development and testing it stores API details, including security, in an off-site storage managed by Postman. It also stores details about employees, teams they are members of, and projects they are working on. This makes it inappropriate for any organization that is required to exercise a high level of security hygiene when developing software products. This issue may be compounded by the lack of details concerning the geolocation of data storage. See More

HilariousHayk's Experience

They random say that I'm was using shared resources and start archiving collections right in front of me without any consideration if you using them at the moment. After archived random collections the only way to recover is to download from the websites some randomized json files with uuuid has names that have nothing to do with the stuff that was archived.

hbko's Experience

Paw is a very efficient and Mac-friendly app for working with APIs. It has a rich selection of extensions for importing and exporting requests, responses and handling authentication providers. It also makes it really easy to use dynamic response values as part of related requests (e.g. a request to get a token and then use a token in another request). The JSON response preview is really powerful with the ability to query and filter large data sets. See More

Top Con

Zero help with getting started in the documentation

Finch Loe's Experience

Why Insomnia Is The 51st Shade Of Grey Initially, severe insomnia symptoms may not require adequate treatment. If a person feels tired and cannot perform his physical activities during the day, he should buy sleeping pills for a short time as per the prescription of his doctor or physician. Consult your doctor, get a proper check-up, explain all the problems including your sleep schedule. The doctor may also ask your family members about your problems. Zopiclone 10mg dose for adults can reduce these symptoms of this disorder. https://www.pharmahealthonline.com/sleeping-aid/why-insomnia-is-the-51st-shade-of-grey/ https://www.pharmahealthonline.com/shop/sleeping-aid/zopiclone-10-mg/ See More
