Shiprocket FASTRR – Custom Success Page Redirect Not Working

Technical Q&A

Topic summary

Custom redirect after Shiprocket FASTRR (headless checkout) success is failing. Goal: send customers to /pages/order-success once the FASTRR success page loads.

Setup: an external JS file (order-success-redirect.js) is included via theme.liquid to run the redirect.

Observed behavior: the script does not execute, no console logs appear, no redirect occurs, while FASTRR’s success overlay renders normally.

Suspected cause: environment restrictions such as CSP (Content Security Policy limiting script execution) or the checkout running within an iframe (which can isolate page scripts and block redirects).

Request: a reliable way to trigger a redirect after the FASTRR success page loads, given these constraints.

Status: no solution or workaround provided; the issue remains open.

Notes: FASTRR is Shiprocket’s headless checkout; CSP and iframes can prevent external scripts from interacting with embedded checkout pages. No images or attachments are central.

Hi,
I’m using Shiprocket FASTRR (Headless Checkout) and trying to redirect customers to my custom page:

/pages/order-success

I added a redirect script inside an external JS file (order-success-redirect.js) and loaded it in theme.liquid, but:

  • The script does not run

  • No console logs

  • No redirect happens

  • The success overlay shows normally

It seems Shopify or FASTRR may be blocking the script (CSP or iframe).
Does anyone know how to trigger a redirect after the FASTRR success page loads?

Any help would be appreciated!
