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().
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(). Such APIRequestContext
object will have its own isolated cookie storage.

Methods deleteAdded in: v1.16 apiRequestContext.delete
Sends HTTP(S) DELETE 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.
Usage
api_request_context.delete(url)
api_request_context.delete(url, **kwargs)
Arguments
Target URL.
data
str | bytes | Dict (optional) Added in: v1.17#
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.
fail_on_status_code
bool (optional)#
Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status codes.
form
Dict[str, str | float | bool] (optional) Added in: v1.17#
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.
headers
Dict[str, str] (optional)#
Allows to set HTTP headers. These headers will apply to the fetched request as well as any redirects initiated by it.
ignore_https_errors
bool (optional)#
Whether to ignore HTTPS errors when sending network requests. Defaults to false
.
max_redirects
int (optional) Added in: v1.26#

. Pass 0
to not follow redirects.
max_retries
int (optional) Added in: v1.46#
Maximum number of times network errors should be retried. Currently only ECONNRESET
error is retried. Does not retry based on HTTP response codes. An error will be thrown if the limit is exceeded. Defaults to 0
- no retries.
multipart
Dict[str, str | float | bool | [ReadStream] | Dict] (optional) Added in: v1.17#
Provides an object that will be serialized as html form using multipart/form-data
encoding and sent as this request body. If this parameter is specified content-type

Arguments
reason
str (optional) Added in: v1.45#
