Make an HTTP API request to a specified URL and store the response as an output.

This task makes an API call to a specified URL of an HTTP server and stores the response as an output. Kestra offers 600+ plugins. Before using the generic HTTP task, check if a dedicated plugin fits your use case — it's recommended to use plugins first and only fall back to HTTP when needed. By default, the maximum length of the response is limited to 10MB, but it can be increased to at most 2GB by using the options.maxContentLength property. Note that the response is added as an output of the task. If you need to process large API payloads, we recommend using the Download task instead.

Examples

Execute a Kestra flow via an HTTP POST request authenticated with basic auth. To pass a user input to the API call, we use the formData property. When using form data, make sure to set the contentType property to multipart/form-data.

yaml
id: api_call
namespace: company.team

tasks:
  - id: basic_auth_api
    type: io.kestra.plugin.core.http.Request
    uri: http://host.docker.internal:8080/api/v1/executions/dev/inputs_demo
    options:
      basicAuthUser: admin
      basicAuthPassword: admin
    method: POST
    contentType: multipart/form-data
    formData:
      user: John Doe

Execute a Kestra flow via an HTTP request authenticated with a Bearer auth token / JWT token.

yaml
id: jwt_auth_call
namespace: company.team

tasks:
  - id: auth_token_api
    type: io.kestra.plugin.core.http.Request
    uri: https://dummyjson.com/user/me
    method: GET
    headers:
      Authorization: 'Bearer <TOKEN>'

Execute a Kestra flow via an HTTP request authenticated with API key passed in the header.

yaml
id: api_key_auth_call
namespace: company.team

tasks:
  - id: api_key_auth
    type: io.kestra.plugin.core.http.Request
    uri: https://dummyjson.com/user/me
    method: GET

      X-API-KEY: abcde12345

Execute a Kestra flow via an HTTP request authenticated with API key passed in the query parameters.

yaml
id: api_key_auth_call

tasks:
  - id: api_key_in_query_params
    type: io.kestra.plugin.core.http.Request
    uri: "https://dummyjson.com/user/me?api_key={{ secret('API_KEY') }}"
    method: GET

Make an HTTP GET request with a timeout. The timeout property specifies the maximum time allowed for the entire task to run, while the options.connectTimeout, options.readTimeout, options.connectionPoolIdleTimeout, and options.readIdleTimeout properties specify the time allowed for establishing a connection, reading data from the server, keeping an idle connection in the client's connection pool, and keeping a read connection idle before closing it, respectively.

yaml
id: timeout
namespace: company.team

tasks:
  - id: http
    type: io.kestra.plugin.core.http.Request
    uri: https://reqres.in/api/long-request
    timeout: PT10M # no default
    method: GET
    options:
      connectTimeout: PT1M # no default
      readTimeout: PT30S # 10 seconds by default
      connectionPoolIdleTimeout: PT10S # 0 seconds by default
      readIdleTimeout: PT10M # 300 seconds by default

    method: POST
    contentType: application/json
    body: "{{ inputs.payload }}"

Properties

uri *string

The fully-qualified URI that points to the HTTP destination

body string

The full body as a string

contentType string

Default application/json

The request content type

encryptBody booleanstring

Default false

If true, the HTTP response body will be automatically encrypted and decrypted in the outputs, provided that encryption is configured in your Kestra configuration.

If this property is set to true, this task will output the request body using the encryptedBody output property; otherwise, the request body will be stored in the body output property.

}

The HTTP request options

Outputs

body object

The body of the response.

Kestra will by default store the task output using this property. However, if the encryptBody property is set to true, kestra will instead encrypt the output and store it using the encryptedBody output property.

code integer

encryptedBody string

The encrypted body of the response.

If the encryptBody property is set to true, kestra will automatically encrypt the output before storing it, and decrypt it when the output is retrieved in a downstream task.

formData object

The form data to be sent in the request body

When sending a file, you can pass a list of maps (i.e. a list of key-value pairs) with a key 'name' and value of the filename, as well as 'content' key with the file's content as value (e.g. passed from flow inputs or outputs from another task).
