description	ShortStack (shortstack.com) platform help — campaign platform for contests, giveaways, sweepstakes, quizzes, refer-a-friend, instant-win, and hashtag/comment-to-enter promotions, with lead capture, automatic winner selection, and analytics. Developer surface: an Entries API (`entries.shortstack.com`, `Authorization: Token token=`, per_page ≤5000, `{data:[...]}` response) and real-time signed webhooks (`X-Ss-Signature` HMAC of body + secret) on each new entry, plus a Webhooks management API, native Mailchimp/HubSpot/Salesforce, and Zapier. Free-forever plan + paid tiers. Use when reading entries/leads via the API, verifying or wiring the signed webhook, syncing entrants to an ESP/CRM or Zapier, picking a campaign type, handling giveaway fraud, or exporting leads. Do NOT use for giveaway/audience-growth strategy across tools (use /sales-audience-growth), generic iPaaS wiring (use /sales-integration), or email deliverability (use /sales-deliverability).

ShortStack Platform Help

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated platform knowledge.

1. What are you trying to do?

   • A) Read entries/leads via the Entries API (paging, newest-first)
   • B) Receive entries in real time via the signed webhook (and verify X-Ss-Signature)
   • C) Sync entrants to an ESP/CRM (Mailchimp/HubSpot/Salesforce) or Zapier
   • D) Pick + set up a campaign type — contest, sweepstakes, quiz, refer-a-friend, instant-win, hashtag/comment-to-enter
   • E) Handle giveaway fraud / fake entries, or pick a winner fairly
   • F) Decide Free vs a paid tier, or export leads

2. API or no-code? Code integration → Entries API + signed webhooks. No endpoint → native ESP/CRM connectors or Zapier.

Skip-ahead rule: if the user's prompt already provides enough context, skip to Step 2.

Step 2 — Route or answer directly

If the question is about...	Route to...
Giveaway / audience-growth strategy across tools (which tool, viral mechanics)	/sales-audience-growth {question}
Connecting ShortStack to a CRM/ESP generically (iPaaS)	/sales-integration {question}
Email sequences for the list you collect	/sales-email-marketing {question}
Deliverability of giveaway/notification emails	/sales-deliverability {question}

When routing, give the exact command, e.g. "This is a strategy question — run: /sales-audience-growth maximize entries on a refer-a-friend contest".

Step 3 — ShortStack platform reference

Read references/platform-guide.md for the full reference — the campaign-type + module map (what's API vs webhook vs UI-only), the entry/lead data model, plan tiers, and quick-start recipes (pull entries via the API; verify the signed webhook; sync to an ESP).

Read references/shortstack-api-reference.md for the integration surface — the Entries API (base https://entries.shortstack.com/entries, Authorization: Token token= header, per_page ≤5000, sort/direction, {data:[...]} response) and the signed webhook (X-Ss-Signature = HMAC of request body + your secret key) that fires on each new entry, plus the Webhooks management API + sandbox.

Answer using only the relevant section. Don't dump the full reference.

Step 4 — Actionable guidance

Focus on the user's specific situation:

• Read entries with the token header. GET https://entries.shortstack.com/entries with Authorization: Token token=YOUR_API_KEY; page newest-first with sort=received&direction=descending&per_page=… (max 5000). Response is { "data": [ … ] }.
• Verify the webhook signature. ShortStack signs each webhook with X-Ss-Signature = HMAC(request body + secret). Recompute and constant-time compare before trusting the payload — this is a real signed webhook, so use it (don't skip verification). Still dedupe on the entry id.
• Prefer a native ESP/CRM connector when you can. Mailchimp/HubSpot/Salesforce sync directly; use Zapier or the webhook only when you need custom routing.
• Pick the campaign type to the goal. Contests/sweepstakes for reach, quizzes for segmentation, refer-a-friend for virality, instant-win for engagement, hashtag/comment-to-enter for social. Winner selection is automatic.
• Plan for fraud. Viral contests attract fake/disposable entries and multi-entry abuse — validate emails before counting/rewarding and review entries before drawing a winner.
• Mind the plan. Free-forever plan exists; advanced features, entry volume, and white-labeling scale with paid tiers (best-effort — verify current pricing). ShortStack also serves big brands/agencies, so tiers run up to enterprise.

If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.

Gotchas

Best-effort from research (2026-06) — the help center is Cloudflare-protected, so some API/pricing specifics are from indexed sources; verify in-account.

1. Entries API auth is a token header. Authorization: Token token=YOUR_API_KEY (note the token= prefix) — not a bare bearer; a wrong format 401s.
2. per_page max is 5000 (default 100). For large accounts, page with sort=received&direction=descending and confirm the cursor/offset for beyond 5000 in the live docs.
3. The webhook IS signed — verify it. X-Ss-Signature is an HMAC of the body + your secret. Unlike many giveaway tools (no HMAC), you can and should verify authenticity; failing to is the main security gap.
4. Campaigns are UI-built. The API reads entries and manages webhooks; you don't create campaigns via API. Build them in the app.
5. Help center is bot-protected. Exact endpoint catalog + entry/webhook payload schema need confirming in-account (Cloudflare blocks automated fetches).
6. Contests attract fraud. Disposable emails, same-person multi-entry — validate before counting and review before awarding.
7. Tiers scale to enterprise. A free plan exists, but advanced/volume/white-label features are paid; ShortStack's bigger customers are enterprise/agencies, so confirm what your tier includes.

Examples

Example 1: Pull new entries into my system via the API (developer/automation)

User says: "How do I fetch the latest entries from my ShortStack campaign programmatically?" Skill does: Shows GET https://entries.shortstack.com/entries with the Authorization: Token token=YOUR_API_KEY header, using sort=received&direction=descending&per_page=50 to get newest-first (max 5000), and parsing the { "data": [ … ] } response. Notes the API reads entries (campaigns are UI-built) and recommends the signed webhook for real-time instead of polling. Result: A working, paged pull of the campaign's entries.

Example 2: Verify the entry webhook so I can trust it

User says: "ShortStack is POSTing entries to my endpoint — how do I make sure they're really from ShortStack?" Skill does: Explains the X-Ss-Signature header is an HMAC of the request body + your secret key; the handler should recompute the HMAC over the raw body and constant-time compare to the header, rejecting on mismatch. Adds dedupe on the entry id (retries) and treating the endpoint as secret. Notes Zapier as a no-code alternative if they don't want to host an endpoint. Result: Authenticated, tamper-evident webhook intake.

Example 3: Which campaign type — and how do entries flow to my ESP?

User says: "I want a refer-a-friend giveaway that adds entrants to Mailchimp. What do I pick?" Skill does: Recommends the refer-a-friend campaign type for virality and the native Mailchimp connection (direct) so entrants sync automatically — or Zapier/the webhook for custom routing. Flags double-opt-in + fraud filtering before nurture, automatic winner selection at the end, and routes deeper viral-mechanics strategy: "run: /sales-audience-growth maximize referrals on a giveaway." Result: The right campaign type wired to the user's ESP.

Troubleshooting

My Entries API calls return 401

Symptom: Requests to entries.shortstack.com/entries are rejected as unauthorized. Cause: The auth header is malformed — ShortStack expects Authorization: Token token=YOUR_API_KEY (the literal Token token= prefix), not Bearer ... or a bare key. Solution: Send exactly Authorization: Token token=YOUR_API_KEY (key from account settings), over HTTPS, to https://entries.shortstack.com/entries. Test with curl -i -H "Authorization: Token token=$API_KEY" "https://entries.shortstack.com/entries?per_page=25".

My webhook signature check keeps failing

Symptom: The HMAC you compute doesn't match X-Ss-Signature. Cause: Signing over a re-serialized/parsed body instead of the raw bytes, a wrong secret, or the wrong HMAC encoding. Solution: Compute the HMAC over the raw request body (before any JSON parsing) using your shared secret key, match the encoding ShortStack uses, and constant-time compare to X-Ss-Signature. Capture a live delivery to confirm the exact scheme (the help center is bot-protected). Once verified, dedupe on the entry id.

My contest is full of fake entries

Symptom: A spike of disposable-email or duplicate entries. Cause: Viral contests attract fraud — disposable emails, multi-entry, bots. Solution: Validate/verify emails before counting, watch for same-person multi-entry, add friction (double opt-in), and review entries before the automatic winner draw. For list quality/deliverability afterward, use /sales-deliverability.
