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 browserContext.request or page.request. It is also possible to create a new APIRequestContext instance manually by calling apiRequest.newContext([options]).

Cookie management

APIRequestContext returned by browserContext.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 apiRequest.newContext([options]). Such APIRequestContext object will have its own isolated cookie storage.

apiRequestContext.delete(url[, options])​

Added in: v1.16
  • url <string> Target URL.#
  • options? <Object>
    • data? <string|Buffer|Serializable> Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string and content-type header will be set to application/json if not explicitly set. Otherwise the content-type header will be set to application/octet-stream if not explicitly set. Added in: v1.17#
    • failOnStatusCode? <boolean> Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status codes.#
    • form? <Object<string, string|number|boolean>> Provides an object that will be serialized as html form using application/x-www-form-urlencoded encoding and sent as this request body. If this parameter is specified content-type header will be set to application/x-www-form-urlencoded unless explicitly provided. Added in: v1.17#

apiRequestContext.dispose()​

Added in: v1.16

All responses returned by apiRequestContext.get(url[, options]) and similar methods are stored in the memory, so that you can later call apiResponse.body(). This method discards all stored responses, and makes apiResponse.body() throw "Response disposed" error.

apiRequestContext.fetch(urlOrRequest[, options])​

Added in: v1.16
  • urlOrRequest <string|Request> Target URL or Request to get all parameters from.#
  • options? <Object>
    • data? <string|Buffer|Serializable> Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string and content-type header will be set to application/json if not explicitly set. Otherwise the content-type header will be set to application/octet-stream if not explicitly set.#
    • failOnStatusCode? <boolean> Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status codes.#
    • form? <Object<string, string|number|boolean>> Provides an object that will be serialized as html form using application/x-www-form-urlencoded encoding and sent as this request body.

    • params? <Object<string, string|number|boolean>> Query parameters to be sent with the URL.#
    • timeout? <number> Request timeout in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout.#
  • returns: <Promise<APIResponse>>#

Sends HTTP(S) request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

JSON objects can be passed directly to the request:

await request.fetch('https://example.com/api/createBook', {
  method: 'post',
  data: {
    title: 'Book Title',
    author: 'John Doe',
  }
});

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:

// Open file as a stream and pass it to the request:
const stream = fs.createReadStream('team.csv');
await request.fetch('https://example.com/api/uploadTeamList', {
  method: 'post',
  multipart: {
    fileField: stream
  }
});

// Or you can pass the file content directly as an object:
await request.fetch('https://example.com/api/uploadScript', {
  method: 'post',
  multipart: {
    fileField: {
      name: 'f.js',
      mimeType: 'text/javascript',
      buffer: Buffer.from('console.log(2022);')
    }
  }
});

await request.post('https://example.com/api/createBook', {
  data: {
    title: 'Book Title',
    author: 'John Doe',
  }
});

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):

await request.post('https://example.com/api/findBook', {

const stream = fs.createReadStream('team.csv');
await request.post('https://example.com/api/uploadTeamList', {
  multipart: {
