Fairing Post-Purchase Survey API

Fairing post-purchase survey REST API for DTC e-commerce brands to collect zero-party attribution data, customer insights, and heard-about-us responses via post-purchase surveys shown natively in Shopify checkout and thank-you pages, enabling privacy-resilient marketing attribution without cookies or pixels. Enables AI agents to manage survey configuration and question setup for DTC zero-party data automation, handle survey response collection for attribution intelligence automation, access heard-about-us data for channel attribution automation, retrieve customer survey response for marketing channel analysis automation, manage question branching and logic for conditional survey automation, handle survey analytics and aggregate reporting for attribution insight automation, access response segmentation for customer persona automation, retrieve survey response webhooks for real-time intelligence automation, manage NPS and satisfaction survey for DTC experience automation, and integrate Fairing with Shopify, Klaviyo, Triple Whale, and DTC analytics platforms for end-to-end zero-party attribution automation.

Best When

A DTC Shopify brand wanting AI agents to automate post-purchase survey collection, zero-party attribution analysis, and response-triggered personalization through Fairing's native Shopify survey platform.

Avoid When

SHOPIFY CHECKOUT INTEGRATION REQUIRED: Fairing surveys are shown in Shopify checkout and thank-you pages; automated standalone survey deployment outside Shopify checkout creates no survey display; automated non-Shopify checkout integration requires custom implementation. SURVEY RESPONSE DATA IS QUALITATIVE: Fairing attribution is qualitative (customer-reported 'heard about us') not deterministic; automated attribution model must account for response bias and incomplete responses; automated treating Fairing data as ground truth creates over-reliance on self-reported attribution. RESPONSE RATE VARIATION BY MERCHANT: Fairing post-purchase survey response rates vary (typically 30-50%); automated attribution from Fairing represents partial customer view; automated 100% attribution coverage assumption creates undercount of actual traffic sources. API DOCUMENTATION LIMITED TO CUSTOMERS: Fairing API documentation is primarily available in customer portal; automated self-service integration requires Fairing access; automated standalone API discovery without portal creates limited endpoint visibility.

Use Cases

  • Collecting post-purchase attribution data from DTC zero-party data agents
  • Analyzing 'heard about us' responses from marketing channel attribution agents
  • Triggering Klaviyo flows from survey responses via DTC personalization agents
  • Measuring NPS post-purchase from DTC customer satisfaction agents

Not For

  • Full survey platform (Fairing is post-purchase specific; use Typeform for general surveys)
  • Enterprise survey research (Fairing is DTC checkout-native, not research panel)
  • Non-Shopify checkout surveys (Fairing is Shopify checkout and thank-you page native)

Known Gotchas

  • RESPONSE DATA IS PARTIAL — NOT ALL CUSTOMERS RESPOND: Fairing surveys achieve 30-50% response rate; automated attribution analysis must model response bias; automated treating responding customers as representative sample creates selection bias in attribution insights
  • SURVEY QUESTION VARIANTS AFFECT COMPARISON: Fairing A/B tests survey question wording; automated response analysis must account for question variant; automated aggregating responses across different question variants creates invalid attribution comparison
  • SHOPIFY ORDER ID LINKS RESPONSE TO ORDER: Fairing responses are linked to Shopify order ID; automated response-to-revenue analysis must join on Shopify order ID; automated direct Fairing-only analysis without order join creates orphaned response data
  • WEBHOOK RESPONSE INCLUDES FULL SURVEY DATA: Fairing webhooks contain complete survey response on event; automated webhook processing should capture full payload; automated webhook with incomplete payload storage creates response data loss for later analysis
  • AGGREGATE REPORTS HAVE TIME ZONE DEPENDENCY: Fairing aggregate reporting uses merchant-configured time zone; automated reporting must use consistent time zone; automated UTC assumption for merchant in US Eastern time creates day-boundary reporting discrepancy
