Frequently asked questions
What is Server-Side GTM?+
Instead of running Google Tag Manager in the user's browser, the server-side approach runs your tagging logic on a server you control. The browser talks to your server, and your server talks to GA4, Meta, TikTok, etc. This bypasses adblockers, extends cookie lifetime, and lets you transform events before they reach vendors.
How is otut.io different from running sGTM on GCP/AWS?+
We handle the entire pipeline — provisioning, monitoring, scaling, edge caching, and the analytics dashboard. You bring a GTM container config and we give you a subdomain + container + dashboard in 10 minutes. No DevOps required.
What does the Power Loader do?+
It's a 4KB anti-adblock loader script. It checks whether GTM is reachable, and if not (because the user has an adblocker), it loads a fallback script that sends first-party requests to your own subdomain. Combined with sGTM hosting on that subdomain, you bypass 95%+ of adblockers.
Do you support Meta CAPI?+
Yes — built-in. We generate Meta's `fbq('init')` and `fbq('track', 'PageView')` payloads on the server with hashed PII, then POST to your Conversions API endpoint. Score and dedup window are configurable per container.
What payment methods do you accept?+
bKash only at the moment (manual reconciliation — we send instructions, you send us the trx ID, we verify and activate). Card / Stripe is on the roadmap.
Can I cancel anytime?+
Yes. Cancel from your dashboard and your subscription won't renew. You keep access until the end of the period. We also offer a 14-day money-back guarantee on first purchase.
