Postman Export

Rext HTTP can export your requests as Postman Collections v2.1, automatically translating @capture, @assert, @pre, and @group to their native Postman equivalents.

How to Export

From the Editor

1. Open a .rext file
2. Place your cursor on a request
3. Ctrl+Shift+P → “Rext: Export Request”
4. Select ”📦 Postman Collection”

From the Sidebar

• Full file — Right-click a file → 📦 Export to Postman
• Collection — Click the 📦 button on the collection header, or right-click → Export to Postman
• Group — Click the 📦 button on the group header, or right-click → Export to Postman

From the Results Panel

1. Execute a request
2. In the results panel, click Export ▾
3. Select 📦 Postman Collection

Export Entire Workspace

Ctrl+Shift+P → “Rext: Export All to Postman Collection” — exports all .rext files in the workspace as a single collection.

Directive Translation

@capture → Test Scripts

@capture env.token = body.access_token
@capture global.apiKey = body.key
@capture collection.refreshToken = body.refresh_token

Becomes:

pm.environment.set("token", pm.response.json().access_token);
pm.globals.set("apiKey", pm.response.json().key);
pm.collectionVariables.set("refreshToken", pm.response.json().refresh_token);

@assert → pm.test()

@assert status == 200
@assert body.email exists
@assert body.items isArray
@assert body.name contains "John"

Becomes:

pm.test("status == 200", function () {
    pm.response.to.have.status(200);
});
pm.test("body.email exists", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.email).to.exist;
});

@group → Folders

@group Auth/Login

Creates nested folders Auth > Login in the Postman collection.

@pre → Pre-request Scripts

@pre abc123

Translates to a pm.sendRequest() in the Pre-request Script that executes the referenced request with its URL, method, headers, and body.

External Pre-requests

When exporting a request with @pre and the pre-request is not included in the export:

1. Rext searches for the pre-request across the workspace
2. Shows a dialog asking:
   • “Yes, include” — Adds the pre-request as an additional item in the Postman collection
   • “No, just pm.sendRequest()” — Keeps only the inline script

Tip

If you include the pre-request as a separate item, you can run the full collection in Postman’s Collection Runner and requests will execute in the correct order.

Output Format

The exported file is a standard Postman Collection v2.1 JSON:

{
  "info": {
    "name": "My Collection",
    "schema": "https://schema.getpostman.com/json/collection/v2.1.0/collection.json"
  },
  "item": [...]
}

You can import it directly into Postman with File → Import.
