API Calls - LambdaTest

Using Claude Code, Cursor, or another coding agent? Paste this into your prompt to run cross-browser and real-device tests, debug sessions, and wire up CI on the TestMu AI cloud:

Read https://www.testmuai.com/support/docs/SKILL.md to set up TestMu AI (formerly LambdaTest) cloud testing.

Objectives can have the agent make an API call directly, not just observe the requests a page makes. This is useful for seeding data before a flow, hitting a backend to set up state, or checking a service, then asserting on or reusing the response.

Making a call

Phrase an explicit HTTP request and name its response with “save the response as …”:

Call POST https://api.example.com/orders with body {"item": "sku_42", "qty": 1}, save the response as order
Hit GET https://api.example.com/orders/123, save the response as fetched
Call DELETE https://api.example.com/orders/123

A pasted curl works too and is kept exactly as written: method, headers, body, and auth:

curl -X POST https://api.example.com/login -H 'Content-Type: application/json' -d '{"u":"a","p":"b"}', save the response as login

Using the response

Once you’ve saved a response under a name, reference it elsewhere in the objective:

Reference	Resolves to
`{{order.status}}`	the HTTP status code (e.g. `201`)
`{{order.response_body}}`	the whole response body
`{{order.response_body.<field>}}`	a field from the JSON response body

Assert on it, or feed it into later actions. API calls and browser actions mix freely in one objective:

Call POST https://api.example.com/login with body {"u": "{{user}}", "p": "{{password}}"}, save the response as login,
assert {{login.status}} is 200,
then open https://app.example.com and verify the dashboard loads

Call POST https://api.example.com/orders with body {"item": "sku_42", "qty": 1}, save the response as order,
assert {{order.status}} is 201,
then open https://app.example.com/orders and verify an order for "sku_42" is visible

Tokens and secrets

Put any API token or credential in a variable marked secret: true (see Variables and Context) so it is masked in logs and never stored in plain text:

curl -X DELETE https://api.example.com/records/42 -H "Authorization: Bearer {{api_token}}"

Make a call vs. observe page traffic

These are two different things:

Make a call (this page): you tell the agent to send a request: seed a record, call a backend, set up state.
Network assertions: observe the requests the page itself makes during a UI flow (status codes, bodies, timing).

They compose: seed state with a direct call, drive the UI, then assert on the page’s own network traffic.
