Lemonsqueezy Payments

Hi All,

Lemonsqueezy is a merchant of record (MoR) like paddle.com, which are alternative payment processors to Stripe/PayPal that handle all the tax collection and remittances. It basically acts like a reseller of your software so you can just get payouts and not have to worry about sales tax. I decided to give it a go for my SaaS since I want to sell worldwide.

Note that this code is not production ready.

My anvil-squared dependency has some functions that’ll generate checkouts and create customer portal links:

github.com

yahiakala/anvil-squared/blob/master/server_code/lemons.py

"""Interacting with LemonSqueezy API."""
import anvil.server
import anvil.http
import anvil.secrets
import json
import hmac
import hashlib

url = "https://api.lemonsqueezy.com/v1/checkouts"


def create_checkout(api_key=None, variants=[], store_id=None,
                    selected_variant=None, user_email=None, test_mode=True,
                    redirect_url=None):
    """Create a custom checkout URL."""
    if not api_key:
        api_key = anvil.secrets.get_secret('lemon_api_key')
    if not variants:
        variants = ['261989', '262003', '262005']
    if not store_id:

My boilerplate app has endpoints that correspond to Lemonsqueezy webhooks to catch when a SaaS subscription has been updated:

github.com

"""Interacting with LemonSqueezy API."""
import anvil.server
import anvil.http
import anvil.secrets
import anvil.users
import json
import hmac
import hashlib
from anvil.tables import app_tables

from anvil_squared.helpers import print_timestamp

prod_url = 'app.chatbeaver.ca'


if prod_url in anvil.server.get_app_origin():
    product_id = ''
    lemon_signing = 'LEMON_SIGNING'
    lemon_api = 'LEMON_API'
else:
