### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/cloudflare-workers/cli-reference/invoke) # Cloudflare Workers - Invoke Invokes a deployed function. It allows you to send an event to a deployed function, which can be useful for testing. Cloudflare Workers only support `GET` requests for now. The optional `headers` field allows you to specify headers that will be sent to your Worker along with your request. ```bash serverless invoke --function functionName ``` In the following example, you could run: ```bash serverless invoke --function helloWorld ``` ```yml # serverless.yml ... functions: helloWorld: # What the script will be called on Cloudflare (this property value must match the function name one line above) name: helloWorld # The name of the script on your machine, omitting the .js file extension script: helloWorld events: - http: url: example.com/hello/user # Defines the method used by serverless when the `invoke` command is used. Cloudflare Workers only support GET requests for now method: GET headers: greeting: hi ``` ## Options - `--function` or `-f` The name of the function in your service that you want to invoke. Required. - `--data` or `-d` String data to be passed as an event to your function. By default data is read from standard input. - `--path` or `-p` The path to a json file with input data to be passed to the invoked function. This path is relative to the root directory of the service. ## Provided lifecycle events - `invoke:invoke` ## Examples ### Cloudflare Workers ```bash serverless invoke --function functionName ``` This example will invoke your deployed function on the configured Cloudflare Workers API URL endpoint. This will output the result of the request in your terminal. #### Function invocation with data ```bash serverless invoke --function functionName ```
