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.

serverless invoke --function functionName

In the following example, you could run:

serverless invoke --function helloWorld
# serverless.yml
    # 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
      - http:
          # Defines the method used by serverless when the `invoke` command is used. Cloudflare Workers only support GET requests for now
          method: GET
            greeting: hi
