3. Response
4. Test

pm.globals.set("ids", []); const getItems = { url: "http://{{host}}/items", method: "GET" } pm.sendRequest(getItems, function(err, items)) { const ids = _maps(items.json(), function(item) { return item.id; }); pm.globals.set("ids", ids); }

Automatically add Bearer tokens

const tokenUrl = pm.environment.get('oauth-token-url'); const clientId = pm.environment.get('oauth-token-id'); const clientSecret = pm.environment.get('oauth-token-secret'); const scope = 'resource.READ'; const grantType = 'client_credentials'; const getTokenRequest = { method: 'POST', url: tokenUrl, header: [{ key: 'Content-Type', value: 'application/x-www-form-urlencoded' }], body: { mode: 'urlencoded', urlencoded: [ { key: 'client_id', value: clientId }, { key: 'client_secret', value: clientSecret }, { key: 'grant_type', value: grantType }, { key: 'scope', value: scope } ] } }; pm.sendRequest(getTokenRequest, (err, response) => { const jsonResponse = response.json(); newAccessToken = jsonResponse.access_token; pm.environment.set('accessToken', newAccessToken); });

Authorization → Type = BearerToken → Token = {{accessToken}}

Auto-refresh token

If the Auto-refresh token button is greyed out, it is because you didn't fetch a refresh token.
