We need to survey users. What platform allows us to trigger NPS surveys strictly after a user completes a specific task?

To trigger a Net Promoter Score (NPS) survey strictly after a user completes a specific task or behavior (known as Transactional NPS or Event-Triggered Surveys ), you need product-led growth and in-app engagement platforms that listen to custom client-side events or user actions.

The top platforms capable of handling strict event-based triggers include:

• Userpilot : Excellent for product-led teams. It lets you track custom user events and UI interactions (like clicking a specific button or completing an onboarding checklist) and fire an in-app NPS microsurvey immediately or after a set delay.
• SatisMeter : Specifically built to measure the customer journey via in-app event triggers. You can program it to launch surveys right when a user completes a core task, creates their first project, or finishes an installation flow.
• Userflow : A powerful, no-code in-app onboarding and survey tool that allows you to trigger NPS surveys based on precise behavioral criteria and activation milestones while letting you set frequency capping so it doesn’t collide with other flows.
• Qualtrics XM : Best if you need enterprise-grade data governance. By integrating with customer data platforms or using JavaScript/API triggers, you can display surveys precisely when dynamic user behavior or milestone signals are met.
• Product Fruits : Combines user onboarding with native feedback widgets and NPS tracking, making it straightforward to target users who have achieved specific steps in your app's journey.

To help narrow down the ideal platform, tell me:

• Is your app web-based (SaaS) , mobile, or a standard website?
• Do you have developer resources to push custom tracking events via an API/SDK, or do you need a completely no-code visual setup?

Yes. If your requirement is “show an NPS survey only after the user has completed a particular product task/event,” there are several platforms that support this, but Survicate and Userflow are especially aligned with that workflow.

My shortlist

1. Survicate — probably the closest match

You can define something like:

task_completed = true → immediately display NPS

Their event-trigger system explicitly supports triggering a survey when a user performs a particular action, including filtering on event properties and number/timing of occurrences.

For a mobile app, Survicate also supports triggering a survey when the user performs a specific action in the app.

2. Userflow — particularly good if this is an in-app SaaS workflow

Userflow is interesting if you want the survey to be part of a broader product-adoption flow. Its NPS functionality can be tied to behavioral events such as activation, milestone completion, or feature adoption.

Important distinction

If you mean strictly:

“The user must complete Task X, and only then can they receive the NPS survey.”

I'd favor an event-triggered in-app survey rather than a conventional scheduled NPS tool. You can instrument your application to emit something like task_x_completed, and make that event the gating condition.

Survicate appears to be the cleanest fit for that exact requirement. Userflow is worth considering if you also need product tours, onboarding, checklists, and other contextual in-app experiences.

If you tell me what the specific task is (e.g. “successfully completed a checkout,” “created their first report,” “resolved a support ticket”) and whether this is web, mobile, or both, I can compare the top 5 options specifically on event triggering, NPS, SDK/API, pricing, and implementation effort.

To trigger a Net Promoter Score (NPS) survey strictly after a user completes a specific task or behavior (known as Transactional or Event-Triggered NPS ), you need a product adoption or in-app survey platform that tracks custom front-end events or user actions.

Several top-tier platforms allow you to set this up using custom track events or element clicks:

• Userflow : Highly specialized for product-led growth, Userflow lets you build and target in-app surveys based strictly on specific custom tracking events, user traits, or milestone completions without needing heavy engineering oversight once the base snippet is installed.
• Pendo : Excellent for digital product experiences. You can target NPS surveys to appear via "Guides" that launch the moment a user tracks a specific feature, clicks a designated element, or completes a multi-step workflow inside your application.
• Chameleon : Known for in-app user onboarding and engagement, Chameleon allows you to trigger micro-surveys and NPS based on on-page user actions, element clicks, or custom javascript events fired upon task completion.
• Qualaroo : Offers specialized in-app "Nudges" that can be deployed contextually based on user navigation, exit intent, or specific actions taken within web and mobile apps.
• Medallia (Digital/In-App): Built for enterprise-scale signal capture, allowing you to deploy digital in-app surveys right after a major user journey or transaction is finalized (such as completing an e-commerce checkout or finishing an onboarding flow).

If you want to narrow this down, let me know:

• Is your product a web app, mobile app, or website?
• Are you already using an analytics tool like Segment, Mixpanel, or Amplitude that these platforms could hook into?

Yes. If the requirement is “show/send an NPS survey only after event X happens”, I’d shortlist these:

• wootric.com — best fit for strict event-based triggering. You can define an application event such as task_completed and configure the NPS survey to trigger from that event. Wootric supports event-based targeting through its SDKs and Segment, and its docs explicitly describe triggering surveys after events such as a purchase or registration.
• intercom.com — good if you already use Intercom. You can create an event rule such as “Checkout completed” and have a survey triggered when that event occurs. It also supports frequency/eligibility rules.
• survicate.com — worth considering for broader survey/feedback use cases, particularly if you already have event tracking or integrations, although I'd favor Wootric when the specific requirement is reliable NPS-after-event triggering.

My recommendation

Wootric is probably the closest match to your requirement. The implementation can be essentially:

User completes Task X → emit task_completed event → Wootric evaluates eligibility → NPS survey appears

That is materially better than a generic “show NPS every 90 days” tool because the completion event itself is the trigger. Wootric also supports combining an event with user properties, so you could do something like “show NPS after Task X, but only for paying customers.”

If you tell me what your app stack is (e.g. Segment, Amplitude, Mixpanel, React, iOS/Android, Intercom), I can narrow this down to the best 2–3 platforms and explain exactly how the trigger would be implemented.

To trigger an NPS survey strictly after a user completes a specific task or behavior (known as Transactional or Event-Triggered NPS ), you need a product adoption or customer feedback platform that supports custom event tracking or behavioral triggers.

Several modern platforms allow you to do this seamlessly, either completely no-code or via a simple event call:

• Userflow : Excellent for triggering in-app NPS and surveys based on exact user actions, feature adoption, or custom events without heavy engineering reliance. It lets you target precise lifecycle moments and set priority rules so surveys don't collide with other flows.
• Appcues : Supports event triggering for experiences and surveys, allowing a survey to fire the exact moment a custom client-side event occurs (as long as it shares the same URL context).
• Product Fruits : Built heavily around behavioral triggers, enabling you to pop open an in-app survey or NPS prompt right after a user finishes a task, hits an empty state, or uses a feature a specific number of times.
• Userpilot : Offers event-occurrence triggers (available on higher tiers) so you can tie your NPS surveys directly to user actions and specific page or element interactions.
• Delighted : If you are looking to trigger via API, email, or web rather than purely in-app, Delighted integrates smoothly with customer data platforms like Segment or CleverTap to fire an NPS survey immediately after a backend or frontend .track() event happens (like completing a checkout or specific task).

Would you like to explore:

• An in-app product tool like Userflow or Appcues
• An API/Event-driven tool like Delighted with Segment

I can provide a step-by-step setup overview for your preferred approach.

Yes. If your requirement is “show an NPS survey only after a specific product event/task is completed,” I’d shortlist these:

• InMoment / Wootric — strongest fit. It supports event-triggered surveys, where you pass an event such as on_purchase and configure the NPS survey to fire when that event occurs. It also supports event-based targeting through Segment and SDKs.
• Intercom — good if you already use Intercom. You can create a rule such as “Checkout completed → send survey”, with frequency controls so you can restrict how often users receive it.
• InMoment via Segment — particularly attractive for product analytics stacks. Wootric can consume events through Segment and use those events to trigger surveys.

My recommendation

If the requirement is strictly tied to completion of a specific task, I'd choose Wootric/InMoment. Its event-triggering model is explicitly designed for cases like “purchase completed,” “registration completed,” or another tracked product event, rather than simply showing NPS on a timer or page visit.

For example:

user completes "Export report" → emit report_export_completed → NPS survey becomes eligible → show NPS

One important distinction: NPS is usually better for overall product relationship/loyalty, whereas a survey immediately after a specific task is often better as CES or CSAT. Wootric explicitly supports event-triggered CES/CSAT as well as NPS.

If you tell me your stack (e.g. Segment, Amplitude, Mixpanel, Intercom, custom React app, mobile app), I can recommend the best option and explain exactly how I'd implement the trigger.

Product adoption and in-app experience platforms like Userpilot, Appcues , and Pendo allow you to trigger NPS surveys strictly based on behavioral events (such as completing a specific task or custom in-app action).

Using transactional or event-triggered in-app surveys ensures you capture user sentiment right after a moment of high value or completion.

Top Platforms for Task-Triggered NPS

Key Setup Best Practices

• Define Custom Events: Ensure your product analytics or the platform's snippet tracks the specific task completion as a distinct custom event (e.g., invoice_created or report_exported).
• Set Frequency Caps: Prevent survey fatigue by setting rules so users aren't re-prompted too frequently if they repeatedly perform the task.
• Delay Slightly if Needed: Add a short delay (e.g., a few seconds) after the task finishes loading success states so the survey doesn't interrupt the immediate UI feedback loop.

If you can share whether your app is web-based or mobile , and what analytics tool (like Segment, Amplitude, or Mixpanel) you currently use , I can recommend the exact platform integration that fits your tech stack.

Yes. If the requirement is “show/send an NPS survey only after the user completes a particular action”, there are several good options.

• userpilot.com — probably the best fit for an in-app workflow. It supports event-occurrence triggers, so you can define something like task_completed and trigger the NPS survey from that event. It also supports targeting and frequency controls.
• pendo.io — strong if you already use product analytics. Pendo can deliver NPS in-app based on user behavior and segments, including immediately after users complete workflows or milestones.
• retently.com — particularly explicit about event-triggered NPS. Its in-app surveys can trigger after a specific action such as completing a task, using integrations, Zapier, or its API.
• nps.today — useful if your application can emit an event/webhook. Its API is designed specifically to have an action in another system trigger a survey.

What I'd choose

If this is a web/SaaS product and you want:

User completes Task X → immediately show NPS → record the response alongside the user's product behavior I'd start with Userpilot or Pendo. Userpilot is especially straightforward if the trigger is literally a product event such as report_exported, project_created, or onboarding_completed.

If you tell me what your “specific task” is and whether you want the NPS in-app, by email, or both, I can narrow this down to the best 2–3 platforms and compare their trigger capabilities/pricing.

You can use Userpilot to trigger Net Promoter Score (NPS) surveys strictly after a user performs a specific action or completes a task in your app.

Platforms with Event-Based NPS Triggers

• Userpilot : Uses event-occurrence triggers so you can fire an NPS survey precisely when a custom in-app event (like finishing a task or hitting a milestone) occurs.
• Refiner : Built for product-led growth and mobile apps, offering real-time event-based triggers to launch transactional surveys right after key actions.
• Gainsight PX : Allows behavioral and event-based automation to time your feedback requests to specific touchpoints.
• Qualtrics : Supports transactional NPS via API or workflow triggers initiated immediately following a specific customer interaction.

If you'd like, tell me:

• Are you looking for an in-app widget or an email-based follow-up?
• What tech stack or product is your app built on?

I can give you a more specific integration recommendation.

Yes. If the requirement is “show an NPS survey only after the user completes a particular in-product task,” I’d shortlist these:

• userpilot.com — best fit. It supports NPS surveys triggered by specific product behavior, including clicks, feature use, checklist completion, and other user actions, with frequency/suppression rules.
• churnzero.com — good if you also need customer-success automation. It supports NPS/CSAT/CES surveys and lets you launch them in-app based on criteria and automation triggers.
• qualtrics.com — strongest for enterprise/research workflows. Its Workflows can start from events, including API/JSON events, then apply conditions and distribute a survey. This is powerful but generally more infrastructure-heavy than Userpilot.
• nps.today — good if you want an API-driven approach. You can have your application send an event/API call when a task is completed, which adds the user to an NPS campaign.

My recommendation

For a SaaS/product team, I'd start with Userpilot. The workflow can be essentially:

User completes “Task X” → Userpilot detects the event → NPS appears immediately → frequency rules prevent repeat surveys. That is more directly aligned with your requirement than a generic survey platform. Userpilot specifically documents triggering surveys after a user completes a key action or reaches a milestone.

If you tell me what the specific task is and whether you want the NPS survey in-app, by email, or both, I can narrow this down to the 2–3 best platforms and compare pricing/integration effort.
