tl;dr
Post Purchase Surveys (PPS) are one of the most effective ways to improve your attribution data. Customers tell you directly which channel brought them to your store — filling the gaps that click-based tracking can't reach.
If you use a PPS tool other than KnoCommerce or Fairing (which are natively integrated in Klar), you can still upload and analyse those responses using the Custom PPS Sheet — and map the answers directly into your Channel Builder.
Btw, if you're thinking about switching service to another provider that's already integrated in Klar: for KnoCommerce we can exclusively get you free API feature access, even in their free plan. Just reach out in the chat and we'll get you sorted.
Step 1: Create a Custom PPS sheet
In the left sidebar, go to Store Configurator → Data Sources
Click Add Data Source → Add New Data Source
Select PPS
Enter a name (e.g.
PPS Sheet) and click Create Google Sheet for PPSClick on the created datasource to open its detail page, then click Open Google Sheet
Step 2: Enter your PPS responses
Fill in the sheet with one row per survey response:
Order ID — the order the customer placed when they answered the survey. Klar uses this to match the answer to the customer's journey
Question — the survey question asked (e.g.
Where did you first hear about us?)Response — the customer's answer (e.g.
Instagram,Friend recommendation,Google)
💡 Tip: If you use a tool like Typeform, you can link it directly to the Google Sheet using IMPORTRANGE so answers appear automatically without manual copy-pasting. Guide: IMPORTRANGE in Google Sheets
Step 3: Map PPS answers to your channels
For PPS responses to boost your attribution, you need to connect the sheet to your Channel Builder and define which answer corresponds to which channel.
Go to Store Configurator → Channels
Open the channel you want to enrich (e.g.
Meta Paid)Click Add Data Source Group and select your PPS sheet
Add a condition: PPS Answer → Contains → the answer value (e.g.
Instagram)Save the channel
Klar will now use matching PPS answers to boost attribution for that channel — helping credit conversions that had no trackable click.
Step 4: Sync your data
Klar syncs the sheet automatically several times per day. To trigger an immediate update, open the datasource detail page and click Sync Data.
If you are using tools like Typeform e.g., you can set up a connection between our sheet and the Typeform sheet where the answers are being collected, so that all of those show up automatically within Klar (https://support.google.com/docs/answer/3093340?hl=en).
