Need clarity for an integration: Shopify store + Shipstream + Klaviyo - SMS question

Hi @fidelityservices!

Just jumping in to provide a little more information that you might find helpful. @SeanMcC is totally right, if you activate SMS in your Klaviyo account and then design and send SMS campaigns or flows from there, the SMS messages will indeed be sent from Klaviyo. 

However, if you were using one of the platforms in your old stack to send SMS, you may find it helpful to read through our Help Center article, Migrating from another SMS provider to Klaviyo.

As far as your second point, the difficulty of a custom integration can vary greatly depending on how your business is oriented, and what your development capabilities are. I know that your previous platform, Shipstation, has a supported integration that is detailed in this Help Center article. I’m not aware of any supported integration with Shipbridge, so this will have to be a fully custom integration, which will likely be more involved and may need support from a developer. 

Here are some docs from our Developer Portal to help you get started:

• Custom event tracking with JavaScript
• Integrate an ecommerce platform without a pre-built Klaviyo integration

Also, you’re always welcome to reach out to one of our official Klaviyo Partners for development help.

Thanks for using the Community!
