APIRequestContext

This API is used for the Web API testing. You can use it to trigger API endpoints, configure micro-services, prepare environment or the service to your e2e test.

Each Playwright browser context has associated with it APIRequestContext instance which shares cookie storage with the browser context and can be accessed via browser_context.request or page.request. It is also possible to create a new APIRequestContext instance manually by calling api_request.new_context(**kwargs).

Cookie management

APIRequestContext returned by browser_context.request and page.request shares cookie storage with the corresponding BrowserContext. Each API request will have Cookie header populated with the values from the browser context. If the API response contains Set-Cookie header it will automatically update BrowserContext cookies and requests made from the page will pick them up. This means that if you log in using this API, your e2e test will be logged in and vice versa.

If you want API requests to not interfere with the browser cookies you should create a new APIRequestContext by calling api_request.new_context(**kwargs). Such APIRequestContext object will have its own isolated cookie storage.

JSON objects can be passed directly to the request:

data = {

    "body": "John Doe",
}
api_request_context.fetch("https://example.com/api/createBook", method="post", data=data)

The common way to send file(s) in the body of a request is to encode it as form fields with multipart/form-data encoding. You can achieve that with Playwright API like this:

api_request_context.fetch(
  "https://example.com/api/uploadScrip'",

data = {
    "title": "Book Title",
    "body": "John Doe",
}
api_request_context.post("https://example.com/api/createBook", data=data)

To send form data to the server use form option. Its value will be encoded into the request body with application/x-www-form-urlencoded encoding (see below how to use multipart/form-data form encoding to send files):

formData = {

The common way to send file(s) in the body of a request is to upload them as form fields with multipart/form-data encoding. You can achieve that with Playwright API like this:

api_request_context.post(
  "https://example.com/api/uploadScrip'",
  multipart={
