DTC brands run on customer data. An API integration layer makes that data usable instead of siloed.
Shopify, Klaviyo, Gorgias, Loop Returns, PostScript, Attentive — DTC stacks are built from best-in-class tools that don't natively integrate as deeply as the business needs. A custom API integration layer connects them with the logic specific to your brand's operation. Fixed scope, fixed price.
Your DTC brand has a sophisticated tool stack — e-commerce, email/SMS, customer support, returns management — but the data between these tools requires manual export/import or produces incomplete automations with the built-in connections.
DTC brands have the most sophisticated martech stacks of any e-commerce category. The typical growth-stage DTC brand uses 12–18 tools: Shopify for e-commerce, Klaviyo for email, PostScript or Attentive for SMS, Gorgias for customer support, Loop for returns, Rebuy for personalization, Yotpo or Okendo for reviews, Recharge for subscriptions, Triple Whale for analytics, Northbeam for attribution, and Slack for internal operations. Each of these tools does its job well in isolation. The integration points between them are where the gaps live.
The common DTC integration gaps: the customer who initiates a return in Loop doesn't automatically get a retention email from Klaviyo with a discount offer before the return is finalized. The customer who contacts Gorgias support with a product quality complaint doesn't get flagged in Klaviyo for the post-issue recovery sequence. The subscription customer in Recharge who skips three consecutive shipments doesn't trigger the save sequence until someone manually pulls the skip report.
These gaps exist because the native integrations between these tools were built for the most common case, not for the specific customer journey logic your brand has developed. A custom integration layer — an API service that receives events from all of your tools and executes the automation logic specific to your brand — closes the gaps that the native integrations leave open.
A custom API integration layer that connects your DTC tool stack with the automation logic and data flows specific to your brand — eliminating manual work and enabling the customer journeys your built-in integrations can't execute.
Event-driven automation layer
A central webhook-receiving service that collects events from Shopify (orders, cancellations, fulfillments, refunds), Gorgias (tickets, resolutions), Loop (return initiations, approvals, refunds), and Recharge (subscription events). Executes automation logic against these events: Klaviyo segmentation updates, Gorgias tagging, PostScript trigger firing.
Customer lifecycle synchronization
Unified customer lifetime value calculation across Shopify, Recharge, and Loop. CLV and order history pushed to Klaviyo for segmentation. Customer support ticket history flagged in Shopify notes for context at the CS level.
Subscription health automation
Recharge skip and pause events triggering save sequences via Klaviyo and PostScript. Failed payment retry events with staged dunning sequences. Subscription anniversary triggers for loyalty recognition.
Returns flow automation
Loop return initiation triggering a Klaviyo pre-return discount offer for retention. Return approval triggering exchange recommendation based on the returned item and customer history. Return completion updating Klaviyo CLV and segment.
Fulfillment and delivery events
Shipment tracking events from the 3PL (ShipBob, Shipwire, or direct carrier API) triggering Klaviyo and PostScript notification sequences at key delivery milestones. Delivery failure events routing to Gorgias for proactive CS outreach.

Why Fixed-Price Matters Here
DTC brand technology investment is evaluated on the automation revenue and retention impact. Fixed price means the ROI is calculable.

Questions, answered.
The integration layer sits on top of your existing tools — it doesn't replace any of them. Shopify, Klaviyo, Gorgias, and all others continue to work as they currently do. The integration layer adds the automation logic that connects them in ways the native integrations don't.
Rate limit handling is a core concern in the integration layer design. Webhook-triggered operations that need to call external APIs are queued and processed within the rate limits of each connected system, with retry logic for transient failures.
Analytics platform integration — sending events from your DTC tool stack to a data warehouse or analytics platform — is a common extension to the integration layer. All events processed by the integration layer can be forwarded to a Segment-compatible data stream.
Core DTC integration layer (Shopify + Klaviyo + Gorgias + Loop): $22k–$38k. Full stack DTC automation platform: $38k–$65k. Fixed-price.
