# Rewards Fuel

> Contest and sweepstakes software for newsletters, social growth, and customer engagement. Part of the Rewards Fuel incentive stack: RankFuel → Contests → RFWIN. One subscription covers all three products.

Rewards Fuel is the contest engine layer. Build viral giveaways with 20+ entry methods, embed on any site, automate with Make/Zapier, and pick winners with provably-fair RFWIN draws. Free plan available — no credit card required.

Stack chain: **RankFuel** (who's winning) → **Rewards Fuel** (what they win) → **RFWIN** (who provably gets it).

## Make.com integration

- **Status:** Custom app scaffold — submission started (`integrations/make/`)
- **Requires:** Paid plan + API key (`rf_live_…`) with `read` and `hooks` scopes
- **Docs:** https://rewardsfuel.com/developers/webhooks · https://rewardsfuel.com/developers/api

**MVP modules (6):**
| Module | Type | Purpose |
|--------|------|---------|
| Connection test | Connection | Verify API key |
| Make an API call | Universal | Any REST call |
| Watch new contestant | Instant trigger | `contestant.created` webhook |
| Watch winner picked | Instant trigger | `winner.picked` webhook |
| List contests | Search | `GET /contests` |
| Get contest stats | Action | `GET /contests/:id/stats` |

**Setup pattern:**
1. Create Make scenario with Webhooks → Custom webhook
2. Register webhook URL via `POST /webhooks` with desired events
3. Map `type` and `data` from JSON delivery body
4. On scenario delete: `DELETE /webhooks/:id`

**Polling alternative:** HTTP module with Bearer token → `GET /contests` or `GET /contests/:id/stats` (prefer webhooks for real-time).

## Zapier integration

- **Status:** Not yet scaffolded — mirror Make MVP modules when listed
- **Requires:** Paid plan + API key with `hooks` scope (included on new keys)
- **Notify CTA:** https://rewardsfuel.com/contact?subject=Notify+me+when+Zapier+app+launches&message=Please+notify+me+when+the+Rewards+Fuel+Zapier+app+is+available.

**Planned modules (mirror Make):**
- **Triggers:** New Contestant (`contestant.created`), Winner Picked (`winner.picked`)
- **Searches:** List Contests, Get Contest Stats
- **Auth:** Bearer token with `hooks` scope

**Setup today (before official app):**
- **Polling:** Webhooks by Zapier (GET) or custom Zap with Bearer token → `GET /contests`
- **Real-time:** Zapier Catch Hook URL registered via `POST /webhooks`

## REST API v1

- **Requires:** Paid plan + API key
- **Auth:** `Authorization: Bearer rf_live_…`
- **Default scopes on new keys:** `read,hooks,mcp,wp` — add `write` for mutations
- **Rate limit:** 120 requests/minute per key (`X-RateLimit-Remaining`; `429` + `Retry-After`)
