Need to integrate two services(e-shop cms with erp). When the order created in shop, it should appear in erp, and erp changes should be visible in cms.
How do I control deliever of webhook? Tech support said, that they send webhook once, no que, or another attempt to send. Maybe instead of listening for webhook, I should get updates by API, and synchronize somehow in my app?

Should I write my webapp to glue, or better use framework?
