Debugging surveys

PostHog Surveys is a no-code in-app form builder. A customer creates a survey in the PostHog UI; it must then be evaluated and rendered by whichever SDK their app runs. Most "survey not showing" tickets are eligibility problems, not rendering bugs — the SDK correctly decided the user is not eligible, and the job is to find which gate failed and why.

Access requirements

Use PostHog MCP tools or the survey API to inspect survey configuration and responses. A checkout of the PostHog repository is not required for these diagnostic steps.

Cross-SDK feature parity (check this FIRST)

A large class of tickets is "customer expects a feature their platform doesn't support." Confirm the survey's lib / the customer's platform before anything else, then consult this table. Verified against the SDK source — re-verify if it's been months, the gaps get filled over time.
