We integrate with a number of 3rd party systems – using libraries such as cURL (via Guzzle) to access Klaviyo, Discord, and the United States Golf Association;  Incoming webhooks (e.g. from Discord and Typeform); and other integrations such as Postmark for transactional mails, MyWorks for QuickBooks, Skyverge for address validation, ShipStation for shipping, and Metorik for WooCommerce reporting. Addtionally, this is one of the areas Convesio is different from other hosts… we specialize in the “snowflake” configurations. If you have something that is out of the box that is needed, we can usually make accommodations for it. Many other hosts are a flat out no! Just let us know what you need and we can investigate making it happen.
