Show Survey Results Inside Your FlutterFlow App

SurveyMonkey is one of the most widely used survey platforms, with paid plans offering bulk response exports for Team and Enterprise accounts. Its REST API (base URL `https://api.surveymonkey.com/v3`) lets you retrieve the surveys your team has created, pull individual or bulk responses, and fetch the survey structure so you can decode the opaque ID-based answer format into readable text. For a FlutterFlow app — say, an internal dashboard your team opens daily to track NPS scores or employee feedback — this is exactly the kind of pull-and-display integration that works well with FlutterFlow's API Calls panel and Charts widgets.

The critical detail to understand before building is SurveyMonkey's security model. Its OAuth-2 Bearer token grants account-wide read access to every survey and every response you have ever collected. Placing that token in a FlutterFlow API Call header means it ships inside your compiled iOS or Android app binary, where anyone with the right tools can extract it. The correct pattern is to deploy a Firebase Cloud Function or Supabase Edge Function that holds the token server-side. Your FlutterFlow app calls your own proxy URL, and the proxy attaches the Bearer header before forwarding to SurveyMonkey.

A second tool-specific gotcha: SurveyMonkey responses are ID-keyed. When you pull `GET /surveys/{id}/responses/bulk`, the JSON you get back contains question IDs and answer choice IDs — not the human-readable text of your questions or answer options. To build a meaningful dashboard, you also need to call `GET /surveys/{id}/details` to retrieve the question and choice text, then join the two datasets in your backend before returning labelled results to FlutterFlow. Plan for these two calls (or a backend join step) from the start. Rate limits and bulk export availability vary by plan — check current limits in SurveyMonkey's API documentation.

Integration method

FlutterFlow API Call

FlutterFlow API Calls are configured to point at your own backend proxy (a Firebase Cloud Function or Supabase Edge Function) rather than directly at SurveyMonkey's API. The backend proxy holds the OAuth-2 Bearer token securely and forwards requests to `api.surveymonkey.com/v3`, returning survey lists and response data to the Flutter app. This keeps the account-wide token out of the compiled app binary.

Prerequisites

  • A SurveyMonkey account with at least one published survey (paid plan recommended for bulk response access)
  • A developer app registered at developer.surveymonkey.com with an OAuth-2 access token
  • A Firebase project (for Cloud Functions) or a Supabase project (for Edge Functions) connected to FlutterFlow
  • A FlutterFlow project open in the browser
  • Basic familiarity with FlutterFlow's API Calls panel and widget binding

Step-by-step guide

1

Register a developer app and obtain an OAuth-2 access token

Open developer.surveymonkey.com and sign in with your SurveyMonkey account. Click 'My Apps' in the top navigation, then click 'Add a New App'. Give it a name like 'FlutterFlow Dashboard', set the type to Private (for your own account's data), and agree to the terms. Once created, open the app settings and copy the Client ID and Client Secret — you will need these for the OAuth flow. Because this is a private app reading your own surveys, the simplest way to obtain an initial Bearer token is through SurveyMonkey's OAuth-2 authorization code flow. SurveyMonkey's developer docs provide a step-by-step: you visit the authorization URL in a browser (`https://api.surveymonkey.com/oauth/authorize?...`), grant access, receive a code, then exchange it for an access token via a POST to `https://api.surveymonkey.com/oauth/token`. The resulting `access_token` is what your backend proxy will use. Store the Client ID, Client Secret, and access token (plus the refresh token if issued) in your backend environment — in Firebase Functions Config or as Supabase secrets. Never paste these into FlutterFlow. Note which survey IDs you want to display; you can find a survey ID in the SurveyMonkey URL when viewing a survey in your account (`/survey/XXXXXXXX/`).

Pro tip: SurveyMonkey's private-app flow issues long-lived tokens for your own account, which simplifies initial setup. Check whether a refresh token was issued — if so, implement refresh logic in your backend now before the token expires during production use.

Expected result: You have a working OAuth-2 access token stored securely in your backend environment, and you know the IDs of the surveys you want to display.

2

Deploy a backend proxy that holds the token and exposes survey endpoints

Your backend proxy is the security layer between FlutterFlow and SurveyMonkey. Deploy a Firebase Cloud Function (or Supabase Edge Function if you prefer Supabase). The function should expose at least two endpoints that FlutterFlow will call: one to return the list of surveys (`GET /surveys`), and one to return decoded survey results for a given survey ID (which internally calls both `GET /surveys/{id}/responses/bulk` and `GET /surveys/{id}/details`, joins them, and returns labelled data). For the Firebase Cloud Function approach: in the Firebase console, navigate to Functions → Get Started and create a Node.js function. Add the `node-fetch` or `axios` package to your functions/package.json, then write two HTTP-triggered functions. The first fetches your survey list and returns it to FlutterFlow. The second takes a survey ID as a query parameter, fetches both the bulk responses and the survey details in parallel, performs the ID-to-label join (match each answer's `choice_id` to the corresponding `choice` in the details questions array), and returns the combined data. Deploy with `firebase deploy --only functions`. The join step is crucial and easy to underestimate. SurveyMonkey responses contain fields like `{ "question_id": "123", "answers": [{ "choice_id": "456" }] }`. The survey details contain `{ "id": "123", "headings": [{ "heading": "How satisfied are you?" }], "answers": { "choices": [{ "id": "456", "text": "Very satisfied" }] } }`. Your backend must build a lookup map from IDs to text before returning clean data to FlutterFlow. Once the join is done server-side, FlutterFlow just binds clean label/value pairs to its widgets.

11 res.set('Access-Control-Allow-Origin', '*');
12 const r = await fetch(`${SM_BASE}/surveys?per_page=50`, { headers });
13 const data = await r.json();

15});

25 fetch(`${SM_BASE}/surveys/${surveyId}/responses/bulk?per_page=100`, { headers })
26 ]);
27
28 const details = await detailsRes.json();
29 const responses = await responsesRes.json();
30
31 // Build ID -> label maps from survey details
32 const questionMap = {};
33 const choiceMap = {};
34 (details.pages || []).forEach(page => {
35 (page.questions || []).forEach(q => {
36 questionMap[q.id] = q.headings?.[0]?.heading || q.id;
37 (q.answers?.choices || []).forEach(c => {
38 choiceMap[c.id] = c.text;
39 });
40 });
41 });
42
43 // Map responses to labelled data
44 const labelled = (responses.data || []).map(resp => ({
45 id: resp.id,
46 date_modified: resp.date_modified,
47 answers: resp.pages?.flatMap(p => p.questions?.map(q => ({
48 question: questionMap[q.id] || q.id,
49 answer: q.answers?.map(a => choiceMap[a.choice_id] || a.text || a.choice_id).join(', ')
50 })) || []) || []
51 }));
52
53 res.json({ survey_title: details.title, results: labelled });
54});
55

Pro tip: If bulk responses return 403, your SurveyMonkey plan may not support bulk export. Swap to `GET /surveys/{id}/responses` (paginated per-response endpoint) and loop — just mind the rate limits documented in SurveyMonkey's API docs.

Expected result: Two Firebase Cloud Function URLs are deployed and return JSON when tested in a browser: one listing your surveys, one returning labelled results for a given survey ID.

3

Create a FlutterFlow API Call group pointing at your proxy

In your FlutterFlow project, click 'API Calls' in the left navigation bar. Click '+ Add' and choose 'Create API Group'. Name it 'SurveyMonkey' and set the base URL to the root domain of your Firebase Cloud Functions deployment (e.g., `https://us-central1-your-project.cloudfunctions.net`). You do not need to add any Authorization header here — your Cloud Function handles authentication internally. Click 'Save' to create the group. Now add the first API Call within the group. Click '+ Add API Call', name it 'Get Surveys', set the method to GET, and set the endpoint to `/getSurveys` (or whatever path your function uses). Switch to the 'Response & Test' tab, click 'Test', and you should see the survey list JSON. Click 'Generate JSON Paths' so FlutterFlow maps out all the fields automatically — you will see paths like `$.id`, `$.title`, `$.question_count` appear in the JSON Paths list. These are what you will bind to your widgets. Add a second API Call named 'Get Survey Results'. Set the method to GET and the endpoint to `/getSurveyResults`. Switch to the 'Variables' tab and add a variable named `survey_id`. In the endpoint field, add `?id={{survey_id}}` so the survey ID is passed as a query parameter. Head to 'Response & Test', enter a real survey ID in the variable field, click 'Test', and verify you get labelled results back. Generate JSON paths — you should see paths for `$.survey_title`, `$.results[0].id`, `$.results[0].answers[0].question`, `$.results[0].answers[0].answer`.

typescript
1// API Call config reference (for the Get Survey Results call)
2{
3 "method": "GET",
4 "endpoint": "/getSurveyResults?id={{survey_id}}",
5 "headers": {},
6 "variables": [
7 { "name": "survey_id", "type": "String" }
8 ],
9 "sample_json_paths": [
10 "$.survey_title",
11 "$.results[0].id",
12 "$.results[0].date_modified",
13 "$.results[0].answers[0].question",
14 "$.results[0].answers[0].answer"
15 ]
16}
17

Pro tip: Leave the API Call group base URL without a trailing slash, and start each endpoint path with a leading slash. FlutterFlow concatenates them directly — mismatched slashes cause 404s that look confusing.

Expected result: Both API Calls test successfully in FlutterFlow's Response & Test tab, returning real SurveyMonkey data with JSON paths auto-generated.

4

Build a survey list screen and bind the Get Surveys call

On your home or dashboard screen in FlutterFlow, add a ListView widget. Open the widget's data source by clicking on the ListView, then in the right panel choose 'Backend Query' → 'API Call' → select your 'SurveyMonkey' group → 'Get Surveys'. FlutterFlow will fetch the response and let you bind individual fields from the JSON paths you generated. Inside the ListView, add a Card or Container with a Text widget for the survey title, a Text widget for the question count, and an IconButton or gesture to navigate to the results screen. For the title Text, set its value to the API response path `$.title` (from the list item). For the question count, use `$.question_count`. You can also add a small Chip or Badge widget bound to a status field if your response includes one. To navigate to the results screen when a card is tapped, use the Action Flow Editor: select the Card → click the lightning bolt Actions panel → '+ Add Action' → 'Navigate' → select your results page → pass the survey ID (`$.id` from the current list item) as a page parameter. That page parameter will become the `survey_id` variable fed into your second API Call.

Pro tip: If the ListView shows 'No data found' during a web Test Mode run despite the API Call testing successfully, try switching to 'Run Mode' or testing on a real device. API Calls in FlutterFlow can occasionally fail silently in web preview due to CORS restrictions — your Cloud Function's `Access-Control-Allow-Origin: *` header should resolve this, but double-check it is present in the function response headers.

Expected result: The survey list screen shows real surveys pulled from your SurveyMonkey account, with tappable cards that pass the survey ID to the next screen.

5

Build a results screen with Charts and bind the Get Survey Results call

Create a new screen in FlutterFlow for displaying a single survey's results. Add a page parameter called `surveyId` (String type) — this is the ID passed from the list screen when a user taps a survey card. On this screen, add a Text widget at the top bound to `$.survey_title` from the Get Survey Results API call. Below it, add a ListView for the answers list. Configure the ListView's backend query the same way: API Call → SurveyMonkey → Get Survey Results, and for the `survey_id` variable, select 'Page Parameter → surveyId'. Inside the ListView item, add two Text widgets: one bound to `$.results[0].answers[0].question` (the question label) and one to `$.results[0].answers[0].answer` (the answer text). FlutterFlow's item builder will automatically iterate over the `results` array, so each card represents one respondent's answers. For a richer view, add a FlutterFlow Chart widget (Bar or Pie). To power it, you may want to add a second backend query or use a Custom Function to aggregate the answers array into value/label pairs for the chart. This is an optional enhancement — even a simple ListView of labelled answers is already far more useful than raw ID-keyed JSON. Remember: if your SurveyMonkey plan does not support bulk export, you will receive a 403 from the bulk endpoint. In that case, update your Cloud Function to use the paginated single-response endpoint instead and loop to collect all responses before joining.

Expected result: The results screen shows the survey title and a scrollable list of question-and-answer pairs in human-readable text, fetched live from SurveyMonkey via your backend proxy.

Common use cases

NPS dashboard for a SaaS product team

A product team runs monthly NPS surveys via SurveyMonkey. Their FlutterFlow internal app pulls the latest responses, decodes the 0–10 rating answers, and displays a gauge chart for the current NPS score alongside a scrollable list of verbatim comments. No more exporting CSVs — the dashboard refreshes on demand.

FlutterFlow Prompt

Build a dashboard screen that shows the current NPS score as a gauge widget and a ListView of the last 50 survey comments, fetched from our SurveyMonkey account via a backend API.

Employee feedback viewer for an HR app

An HR manager uses a FlutterFlow app to review anonymous engagement survey results. The app fetches the survey details to get question labels, pulls bulk responses, and renders answer distributions as bar charts — all without the HR manager needing to log into SurveyMonkey directly.

FlutterFlow Prompt

Create a screen that lists our engagement surveys, then shows a bar chart of answer distributions for each question when a survey is tapped.

Customer research tracker for a marketing team

A marketing team distributes customer research surveys and wants a mobile-accessible results view. Their FlutterFlow app shows completion rates per survey in a summary card list and lets them drill into individual question breakdowns on a detail screen.

FlutterFlow Prompt

Show a list of our active SurveyMonkey surveys with completion counts. When I tap one, show each question and the percentage breakdown of each answer option.

Troubleshooting

API Call returns 401 Unauthorized or `Error: invalid_token`

Cause: The OAuth-2 Bearer token in your backend proxy has expired or was not correctly set in the Cloud Function environment config.

Solution: Re-check that you stored the token using `firebase functions:config:set surveymonkey.token=...` and redeployed. If the token has expired, repeat the OAuth authorization flow to obtain a fresh access token, update the config, and redeploy. Implement refresh-token rotation in your Cloud Function if SurveyMonkey issued a refresh token alongside the access token.

Results screen shows opaque IDs like `{ question: '123456789', answer: '987654321' }` instead of readable text

Cause: The survey details join step is missing or the ID→label mapping logic in the backend proxy is not running correctly.

Solution: Log the raw output of both `GET /surveys/{id}/details` and `GET /surveys/{id}/responses/bulk` in your Cloud Function to confirm the data shapes. Verify that your `questionMap` and `choiceMap` are being built before the response join loop, and that the question and choice IDs you are looking up match exactly (they should be strings, not numbers). Redeploy the function after fixing.

403 Forbidden when fetching `GET /surveys/{id}/responses/bulk`

Cause: Your SurveyMonkey plan does not include bulk response export, which is restricted to Team and Enterprise plans.

Solution: Switch your Cloud Function to use the paginated endpoint `GET /surveys/{id}/responses?per_page=100` and loop through pages using the `next` link from the response metadata until all responses are collected. Be mindful of rate limits — check current limits in SurveyMonkey's API documentation for your plan tier.

FlutterFlow ListView shows 'No data' even though the API Call Test tab returns data

Cause: A CORS error is blocking the request from FlutterFlow's web Test Mode preview. The browser enforces CORS on web builds, whereas native iOS/Android builds are not affected.

Solution: Confirm that your Cloud Function includes `res.set('Access-Control-Allow-Origin', '*')` before any `res.json()` call, and also handle OPTIONS preflight requests (add a check for `req.method === 'OPTIONS'` that returns 204). After redeploying the function, reload FlutterFlow. For definitive testing, use a real device or FlutterFlow's Local Run instead of web Test Mode.

Best practices

  • Never place the SurveyMonkey OAuth Bearer token in a FlutterFlow API Call header — it grants account-wide read access and ships in your compiled app binary if placed there.
  • Implement refresh-token rotation in your backend proxy from day one if SurveyMonkey issues a refresh token; tokens expire and silent failures in production are hard to debug.
  • Always fetch survey details alongside responses to map IDs to human-readable labels — displaying raw IDs makes the integration appear broken and frustrates users.
  • Use FlutterFlow's 'Variables' tab to pass dynamic survey IDs rather than hardcoding them in endpoints — this makes the same API Call work for every survey in your list.
  • Add loading state indicators (CircularProgressIndicator) on your survey list and results screens — SurveyMonkey responses can be slow for large datasets.
  • Handle the 403 bulk-export response gracefully in your backend and fall back to the paginated per-response endpoint automatically, so your app works on any SurveyMonkey plan.
  • Test your FlutterFlow bindings on a real device or via Local Run rather than web Test Mode — web preview has CORS restrictions that can mask valid API responses.

Alternatives

Frequently asked questions

Can FlutterFlow call the SurveyMonkey API directly without a backend proxy?

Technically yes — you could add the Bearer token as a header in a FlutterFlow API Call. But you should not. The token grants account-wide read access to all your surveys and responses, and placing it in a FlutterFlow API Call means it ships inside the compiled iOS/Android app binary where it can be extracted. Always route through a backend proxy.

Why does my results screen show question and answer IDs instead of text?

SurveyMonkey's responses API returns IDs, not text. You need to make a second call to `GET /surveys/{id}/details` to get the question headings and answer choice text, then join the two datasets by matching IDs. The best place to do this join is in your backend proxy before returning data to FlutterFlow.

Does SurveyMonkey's API work in FlutterFlow's web Test Mode?

Yes, because you are calling your own backend proxy (not SurveyMonkey directly), and your proxy adds the CORS header `Access-Control-Allow-Origin: *`. If you do see CORS errors in web Test Mode, check that your Cloud Function sets this header on all responses, including error responses, and handles OPTIONS preflight requests.

What SurveyMonkey plan do I need for this integration?

Any paid SurveyMonkey plan gives you API access. However, the bulk response export endpoint (`GET /surveys/{id}/responses/bulk`) is restricted to Team and Enterprise plans. On lower tiers you can still pull responses using the paginated single-response endpoint — your backend proxy can handle this automatically by falling back when a 403 is received.

Can I let app users submit survey responses through FlutterFlow?

The SurveyMonkey API does not support submitting responses programmatically via the REST API — responses must be submitted through SurveyMonkey's own web form. If you need users to complete surveys in-app, consider embedding the survey's public URL in a WebView widget instead of using the API.
