Hello World CRON function

POST https://localhost:8080/api/v1/new

{
    "name": "example_function",
    "lang": "py",
    "deployment": {
      "type": "cron",
      "schedule": "0 * * * *"
    },
    "content": "print('Hello, World!')"
}

The above post request would return the following:

{
  "status": {
    "value": 201,
    "message": "CREATED"
  },
  "name": "example_function"
}

Hello World URL function

POST https://localhost:8080/api/v1/new

{
    "name": "example_function",
    "lang": "py",
    "deployment": {
      "type": "url"
    },
    "content": "print('Hello, World!')"
}

The above post could return the following:

{
  "status": {
    "value": 201,
    "message": "CREATED"
  },
  "name": "example_function",
  "endpoint": "8ca0fbdc-831e-45a9-a9a9-eab896d67811"
}

Once created, navigating to the url https://localhost:8080/8ca0fbdc-831e-45a9-a9a9-eab896d67811 would result in the following output:

{
  "stdout": "Hello, World!"
}
