Postman

TIP: Postman: The term 'variable' is used for at least three different things in Postman; (1) query or body parameters exposed as {{var}} driveable variables; (2) Environment variables assigned to such a parameter; (3) Flow specific variables.

WISHLIST: Postman: Ability to hide specific variable rows on a Request block. CASE: Exposed variables driven by Environment variables (which VISUALLY appear empty and take the assigned Environment value unless explicitly connected and overridden)

TIP (GOTCHA): Postman (v11.27.4): The value of a {{var}} set to an Environment variable (specifically) under Request settings is exposed as a Port on a Flow Request but does not VISUALLY APPEAR to take the Environment variable value (but in fact does)

ISSUE: Postman (v11.27.4): The (Mac) Desktop version does not always offer the Output block in a Flow patch

TIP: Postman: Loading a new Open API JSON file as Definition will not override most customised query or body parameter settings on an API Request

TIP: Postman: HOWTO Copy an API Request to a decoupled Collection Request and customise its parameters (or expose specific parameters to drive as Ports on Flows)

ISSUE: Postman (v11.27.4): You can access the underlying Request settings of a Request block in a Flow easily using the little angled arrow at the top of the Request block title, but getting back to the client Flow is cumbersome.

ISSUE: Postman (v11.27.4): Sometimes "stalls" with an incomplete flashing view of the loaded API after uploading a new OpenAPI v3.1 JSON definition file. WORKAROUND: Restart Postman

ISSUE: Postman (v11.27.4): An OpenAPI v3.1 JSON definition file upload does not always "catch". WORKAROUND: Toggle to OpenAPI v3.0 mode then back to OpenAPI v3.1

TIP: Postman: To make a query or body parameter appear as a driveable Port on a Flow Request block you have to expose it as a {{var}} variable under the underlying Request settings

Postman and Postman Flows are simply brilliant technology. It has some foibles, some minor bugs, and some of the workflow and UI/UX could be improved, but ultimately, it's just awesome.

This zone collects some useful links about Postman and Postman Flows, and records some tips, some current issues, and some workarounds.
