Wrapper script for stripe-cli trigger function, opens sender and receiver in split-pane screen sessions.

stripe_test_webhook.sh

#!/bin/bash

# Launches two stripe-cli docker containers, each in its own 'screen' session,
# to test stripe webhook events against a local http server.
#
#   * Launches one container for the listener/forwarder.
#   * Launches one container to trigger the test webhook event.
#
# NOTE: The stripe-cli 'trigger' function will create a lot of data in your
# stripe account's test environment. The only way to remove that data is manual one-by-one
# or by using the 'delete all data' function in your stripe dashboard's test mode.
#
# To start, first get your stripe-api-key into the env var STRIPE_API_KEY. 
#   . file-with-api-key-assignment
#
# Then make sure the variable assignments below suit your setup.
#
# Then run this script.
#   ./<this-script> [local-endpoint-host-with-path] [additional docker options ...]
#
# NOTE: The local-endpoint-host is from the POV of the stripe-cli function running within
# a docker container.
#
# Kill with:
#   exit
#   C-a
#   tab
#   C-c
#   exit
#
# Example:
#    ./this_script.sh stack_app/stripe/webhook --network stack_default

# REQUIRED: Change the name of the api-key env var to suit your setup.
#            or
#           Set this default env var in your app.

# REQUIRED: Change this url to point to your endpoint

# OPTIONAL: If your endpoint is reachable via attachable docker network,
#           set this accordingly. Otherwise comment-out this line.
