Use Sym's HTTP SDK integration to insert side effects throughout your Flows.

Overview

By making arbitrary HTTP requests from your Handlers, you can query internal data stores, trigger side effects in third-party APIs, and more.

🚧

This is an advanced Integration

It's easy to shoot yourself in the foot! With great power comes great responsibility.

Example implementations

Delegating routing to an external service

from sym.sdk.annotations import reducer
from sym.sdk.integrations.dangerous import http

@reducer
def get_approvers(evt):
    body = {"target": evt.target}
    resp = http.get("https://gatekeeper.healthy-health.co", body)
    return slack.group(resp["emails"])

Fetching external state

from sym.sdk.annotations import reducer
from sym.sdk.integrations.dangerous import http

@reducer
def get_approvers(evt):
    email = evt.user.email
    resp = http.get(f"https://people.healthy-health.co?email={email}")
    if resp["is_manager"]:
      # Self-approval:
      return slack.user(evt.user)

Triggering a side-effect

from sym.sdk.annotations import hook
from sym.sdk.integrations.dangerous import http

@hook
def on_request(evt):
    body = {"user": evt.user.email, "message": "requested access"}
    http.post(f"https://audit.healthy-health.co", body)
