KingSumo platform help — the cheap, one-time (lifetime-deal) viral giveaway tool for growing an email list, from the AppSumo team, as both a hosted app and a separate KingSumo Giveaways for WordPress plugin: unlimited giveaways, viral bonus entries (refer-a-friend, social shares/follows, YouTube/podcast subscribe), Smart Auto-Emails, and list capture. Use when a KingSumo giveaway attracts fake or freebie-seeker entries you can't verify, syncing contestants into Mailchimp/ConvertKit/Kit/Klaviyo/SendFox or Zapier, the Zapier integration only offers triggers (New Contestant, New Giveaway) and no actions, contestants see a kingsumo.com URL with no custom domain, choosing Free vs the paid one-time plan, or looking for the fully-featured API but finding no public docs. Do NOT use for picking a giveaway tool across platforms or newsletter list-growth strategy (use /sales-audience-growth), or list deliverability after a giveaway (use /sales-deliverability).

What are you trying to do?
A) Pick a plan — Free (unlimited giveaways + bonus entries) vs the paid one-time/lifetime plan (custom branding, Meta Pixel, conversion tracking, custom rules, extra entry fields, advanced integrations)
B) Set up a viral giveaway and choose bonus-entry actions (refer-a-friend, social shares/follows, YouTube/podcast subscribe, phone)
C) Sync contestants to an ESP/CRM — SendFox, Mailchimp, ConvertKit/Kit, Klaviyo, or via Zapier
D) Wire an automation with the Zapier triggers (New Contestant / New Giveaway) or "Webhooks by Zapier"
E) Use the API to pull contestant/lead data (heads-up: no public docs)
Hosted app or WordPress plugin? They're two different products with different setup and integration paths — confirm which one the user is on before answering.
What's your ESP? Drives whether a native integration (SendFox/Mailchimp/Kit/Klaviyo) is enough or you need Zapier/API glue — and whether you're forced onto the paid plan to unlock advanced integrations.
Skip-ahead rule: if the user's prompt already contains enough context, skip to Step 2.

If the question is KingSumo-specific, continue to Step 3.
Step 3 — KingSumo platform reference
Read references/platform-guide.md for the full reference — the hosted-app vs WordPress-plugin split, plan gating (what the paid one-time plan unlocks), bonus-entry mechanics and the unverifiable-share limitation, ESP/Zapier integration surface, the (undocumented) API, and comparisons with RafflePress / Gleam / SweepWidget / ShortStack / UpViral.
Read references/kingsumo-api-reference.md for the automation surface — the Zapier triggers (New Contestant, New Giveaway) with no actions, the "Webhooks by Zapier" fan-out, native ESP integrations, and what's known (and not documented) about the API.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation:
Confirm which product they're on first. Hosted KingSumo (kingsumo.com) and KingSumo Giveaways for WordPress (a self-hosted plugin, wordpress.kingsumo.com) are separate products with different setup, integration, and Zapier paths. Don't give hosted-app steps to a plugin user or vice versa.
The Zapier integration is trigger-only. KingSumo exposes two triggers — New Contestant (requires selecting a giveaway) and New Giveaway — and no actions. You can push contestants out to any tool; you can't have Zapier create or modify anything in KingSumo. Route webhooks through "Webhooks by Zapier."
Present the API honestly: it exists but has no public docs. Reviewers and the marketing site reference a "fully-featured API" (OAuth-based) on the paid plan, but there is no published endpoint documentation. Don't invent endpoints. For a documented, supported path recommend the native ESP integration or the Zapier New Contestant trigger, and tell the user to contact KingSumo support for API specifics.
Warn that bonus-entry shares can't be verified. KingSumo (like most giveaway tools) can't confirm a contestant actually posted a share — clicking the button awards the entry. Expect gamed entries; validate winners before awarding a prize and don't treat share counts as real reach.
Flag the no-custom-domain limitation. Hosted giveaways live on a kingsumo.com URL — there's no CNAME/custom domain. If the user wants their own domain, tell them to embed the giveaway on their own site instead of linking the hosted page.
Present all pricing as best-effort and point to the live pricing page. It's a one-time/lifetime-deal tool (often sold via AppSumo), and the Free-vs-paid split and price have shifted — confirm at kingsumo.com/pricing before quoting. Advanced integrations, custom branding, Meta Pixel, and conversion tracking are the paid-plan unlocks.
Expect low-quality subscribers and plan for hygiene. Giveaways pull freebie-seekers; a spike of disposable/one-off addresses can hurt deliverability. Recommend double opt-in, list cleaning (/sales-clean-email), and a welcome sequence — route deliverability questions to /sales-deliverability.
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research (2026-07) — review these, especially items about plan-gated features and integrations that may shift. Confirm pricing at kingsumo.com/pricing.
Two separate products. Hosted KingSumo vs KingSumo Giveaways for WordPress — different setup and integration surfaces. Identify which before answering.
Zapier is trigger-only. Triggers: New Contestant (giveaway required), New Giveaway. No actions — you can't write into KingSumo from Zapier.
API has no public documentation. A "fully-featured API" is advertised (OAuth, paid plan) but endpoints aren't published. Prefer native ESP sync or the Zapier trigger; contact support for API specifics. Don't fabricate endpoints.
Shares are unverifiable. Clicking a share button awards the bonus entry whether or not anything was posted. Validate winners; treat viral reach as unproven.
No custom domain / CNAME. Hosted giveaways show a kingsumo.com URL. Embed on your own site if branding/domain matters.
Advanced integrations are paid-plan-gated. Free typically includes SendFox + Zapier; Mailchimp/ConvertKit/Kit/Klaviyo + API access sit on the paid plan (best-effort — verify).
No giveaway templates + fewer entry methods than rivals. Reviewers note more setup work and a smaller viral-entry set than Gleam/SweepWidget/ShortStack.
Giveaway lists skew low-quality. Freebie-seekers and disposable emails inflate signups; clean and double-opt-in before mailing.

Examples
Example 1: Auto-syncing contestants into a CRM via Zapier
User says: "I want every new KingSumo contestant to land in HubSpot automatically. Can Zapier do that both ways?"
Skill does: Explains KingSumo's Zapier app is trigger-only — use the New Contestant trigger (select the giveaway) → HubSpot "Create/Update Contact" action. Notes there are no KingSumo actions, so Zapier can't write back into KingSumo, and that native ESP integrations (SendFox/Mailchimp/Kit/Klaviyo) may be simpler if HubSpot isn't required. Warns that giveaway entries skew low-quality, so recommends tagging them and running double opt-in before nurturing.
Result: User builds a New Contestant → HubSpot Zap, tags the source, and adds a verification step.
Example 2: Looking for the API
User says: "Where are the KingSumo API docs? I want to pull my contestant list programmatically."
Skill does: States plainly that KingSumo advertises a "fully-featured API" (OAuth, on the paid plan) but publishes no endpoint documentation, so it won't invent endpoints. Recommends the supported paths — a native ESP integration or the Zapier New Contestant trigger (optionally "Webhooks by Zapier" to POST to your own endpoint) — and to contact KingSumo support for API keys/specs. Notes competitors with documented APIs (SweepWidget, ShortStack, UpViral) if a real API is a hard requirement.
Result: User wires the Zapier trigger now and files a support request for API access.
Example 3: Fake / gamed entries before drawing a winner
User says: "My giveaway has a ton of entries but the referral shares look fake. How do I trust the winner draw?"
Skill does: Explains KingSumo can't verify that a share was actually posted — clicking the share button awards the bonus entry — so referral/share counts are unreliable. Recommends validating the shortlisted winners manually, using double opt-in to filter disposable addresses, and cleaning the list (/sales-clean-email) before mailing. Points to /sales-deliverability for protecting sender reputation after the influx.
Result: User validates finalists, prunes disposable emails, and draws a verified winner.
Troubleshooting
Zapier won't let me create or update anything in KingSumo
Symptom: You can trigger from KingSumo but can't find a KingSumo action in Zapier
Cause: KingSumo's Zapier app exposes only triggers (New Contestant, New Giveaway) — there are no actions
Solution: Use KingSumo as the trigger and put the write step on the other app (ESP/CRM/Sheets). To send data to a custom endpoint, add a "Webhooks by Zapier" POST action. There is no supported way to write back into KingSumo via Zapier.
API calls fail / I can't find the API documentation
Symptom: You want to hit the KingSumo API but there are no public docs or endpoint references
Cause: KingSumo markets a "fully-featured API" (OAuth, paid plan) but does not publish endpoint documentation
Solution: Don't guess endpoints. Use a native ESP integration or the Zapier New Contestant trigger for a supported data path, and contact KingSumo support for API keys and specifications. If a documented API is mandatory, evaluate SweepWidget/ShortStack/UpViral instead (route via /sales-audience-growth).
Contestants see a kingsumo.com link instead of my domain
Symptom: The hosted giveaway URL is on kingsumo.com and you want it on your own domain
Cause: Hosted KingSumo has no custom domain / CNAME support
Solution: Embed the giveaway on a page of your own site (the embed keeps your domain in the address bar) rather than sharing the hosted kingsumo.com page. Custom branding (logo/colors) is a paid-plan feature; a fully custom domain is not offered — consider a WordPress-plugin or self-hosted alternative if the domain is a hard requirement.
