----
-title: "Custom Subpath"
-description: "Serve Formbricks from a custom URL prefix when you cannot expose it on the root domain."
-icon: "link"
----
-
-<Note>
-  Custom subpath deployments are currently under internal review. If you need early access, please reach out via
-  [GitHub Discussions](https://github.com/formbricks/formbricks/discussions).
-</Note>
-
-### When to use a custom subpath
-
-Use a custom subpath (also called a Next.js base path) when your reverse proxy reserves the root domain for another
-service, but you still want Formbricks to live under the same hostname—for example `https://example.com/feedback`.
-Support for a build-time `BASE_PATH` variable is available in the Formbricks web app so that all internal routes,
-assets, and sign-in redirects honor the prefix.
-
-### Requirements and limitations
-
-- `BASE_PATH` must be present during `pnpm build`; changing it afterward requires a rebuild.
-- Official Formbricks Docker images do **not** accept this flag for technical reasons, so you must build your own image.
-- All public URLs (`WEBAPP_URL`, `NEXTAUTH_URL`, webhook targets, OAuth callbacks, etc.) need the same prefix.
-- Your proxy must rewrite `/custom-path/*` to the Formbricks container while keeping the prefix visible to clients.
-
-### Configure environment variables
-
-Add the following variables to the environment you use for builds (local, CI, or Docker build args):
-
-```bash
-BASE_PATH="/custom-path"
-WEBAPP_URL="https://yourdomain.com/custom-path"
-NEXTAUTH_URL="https://yourdomain.com/custom-path/api/auth"
-```
-
-If you use email links, webhooks, or third-party OAuth providers, ensure every URL you register includes the prefix.
-
-### Build a Docker image with a custom subpath
-
-<Steps>
-  <Step title="Clone Formbricks and prepare secrets">
-    Make sure you have the repository checked out and create temporary files (or use <code>--secret</code>) for the
-    required build-time secrets such as <code>DATABASE_URL</code>, <code>ENCRYPTION_KEY</code>, <code>REDIS_URL</code>,
-    and optional telemetry tokens.
-  </Step>
-  <Step title="Pass BASE_PATH as a build argument">
-    Use the Formbricks web Dockerfile and supply the custom subpath via <code>--build-arg</code>. Example:
-
-```bash
-docker build \
-  --progress=plain \
-  --no-cache \
-  --build-arg BASE_PATH=/custom-path \
-  --secret id=database_url,src=<(printf "postgresql://user:password@localhost:5432/formbricks?schema=public") \
-  --secret id=encryption_key,src=<(printf "your-32-character-encryption-key-here") \
-  --secret id=redis_url,src=<(printf "redis://localhost:6379") \
-  --secret id=sentry_auth_token,src=<(printf "") \
-  -f apps/web/Dockerfile \
-  -t formbricks-web \
-  .
-```
-
-    During the build logs you should see <code>BASE PATH /custom-path</code>, confirming that Next.js picked up the
-    prefix.
-  </Step>
-  <Step title="Run the container behind your proxy">
-    Start the resulting image with the same runtime environment variables you normally use (database credentials,
-    mailing provider, etc.). Point your reverse proxy so that <code>/custom-path</code> requests forward to
-    <code>http://formbricks-web:3000/custom-path</code> without stripping the prefix.
-  </Step>
-</Steps>
-
-### Verify the deployment
-
-1. Open `https://yourdomain.com/custom-path` and complete the onboarding flow.
-2. Create a survey and preview it—embedded scripts now load assets relative to the subpath.
-3. Sign out and confirm the login page still includes `/custom-path`.
-
-### Troubleshooting checklist
-
-- Confirm your build pipeline actually passes `BASE_PATH` (and, if needed, `WEBAPP_URL`/`NEXTAUTH_URL`) into the build
-  stage—check CI logs for the `BASE PATH /your-prefix` line and make sure custom Dockerfiles or wrappers forward
-  `--build-arg BASE_PATH=...` correctly.
-- If you cannot log in, double-check that `NEXTAUTH_URL` includes the prefix and uses the full route to the API as stated above. NextAuth rejects callbacks that do not
-  match exactly.
-- Re-run the Docker build when changing `BASE_PATH`; simply editing the container environment is not sufficient.
-- Inspect your proxy configuration to ensure it does not rewrite paths internally (e.g., `strip_prefix` needs to stay
-  disabled).
-- When in doubt, rebuild locally with `--progress=plain` and verify that the `BASE PATH` line reflects your prefix.

 1. To prefill survey questions, add query parameters to the survey URL using the format `questionId=answer`. 
-2. For choice-based questions, you can use either **option IDs** (recommended) or **option labels** (backward compatible).
-3. The answer must match the question's expected type to pass [validation](/xm-and-surveys/surveys/link-surveys/data-prefilling#validation).
-4. The answer needs to be [URL encoded](https://www.urlencoder.org/) (if it contains spaces or special characters)
-
-### Option IDs vs Option Labels
-
-- **Option IDs (Recommended):** Use the unique ID of each option. These don't change with translations and are more reliable. Example: `?country=choice-us`
-- **Option Labels (Backward Compatible):** Use the exact text of the option. Example: `?country=United%20States`
-
-If you provide a value that matches an option ID, it will be used. Otherwise, the system will try to match it as an option label.

 ## Validation
@@ -154,17 +130,10 @@ The URL validation works as follows:
 - For Rating or NPS questions, the response is parsed as a number and verified if it's accepted by the schema.
 - For CTA type questions, the valid values are "clicked" (main CTA) and "dismissed" (skip CTA).
 - For Consent type questions, the valid values are "accepted" (consent given) and "dismissed" (consent not given).
-- For Picture Selection, Multi-select, and Ranking questions, the response can be comma-separated option IDs or labels.
-- For choice-based questions (Single-select, Multi-select, Ranking, Picture Selection), the system will first try to match as an option ID, then fallback to matching as an option label.
+- For Picture Selection type questions, the response is parsed as an array of numbers and verified if it's accepted by the schema.
 - All other question types are strings.
 
 <Note>
   If an answer is invalid, the prefilling will be ignored and the question is
   presented as if not prefilled.

-## Finding Option IDs
-
-Option IDs are unique identifiers for each choice option in your survey. You can find them in the **Advanced Settings** at the bottom of each question card in the Survey Editor. For choice-based questions (Single-select, Multi-select, Ranking, Picture Selection), the option ID is displayed next to each option.
-
-You can update option IDs to any string you like **before you publish a survey.** After you publish a survey, you cannot change the IDs anymore.
