Webhooks Receive real-time HTTP POST notifications when users enter your giveaway, complete tasks, or finish all entries. Available on Enterprise plans. PlanEnterprise Overview SweepWidget provides two ways to receive real-time event data from your giveaways: Server-side webhooks – HTTP POST requests sent from our server to yours. Work on both embedded widgets and hosted landing pages. Best for backend workflows like CRM syncing, email triggers, and database updates. Client-side JavaScript callbacks – Browser events fired on the page where the widget is loaded. Best for frontend actions like firing tracking pixels, showing custom UI, or triggering analytics events. Both systems fire on the same three events and return the same data. You can use one or both depending on your needs. On this page: Setup Events Payload Format Request Headers Signature Verification JavaScript Callbacks Signing Secret Troubleshooting Setup Server-side webhooks Go to Integrations in your dashboard and click the Webhooks card. Enter your endpoint URL (must use HTTPS) and click Save. Copy the Signing Secret to verify webhook signatures on your server. Use the Send Test button to send a test payload and confirm your endpoint is receiving requests. Note: Webhooks are configured at the account level. Once set up, they fire for all giveaways on your account. JavaScript callbacks No dashboard configuration needed. Add an event listener to the page where your SweepWidget is embedded. See the JavaScript Callbacks section below for code examples. Events All three events fire automatically. There is no per-event toggle. Both webhooks and JS callbacks fire on the same events. Event Fires when entry_submitted A user submits the initial entry form (email, name, etc.) task_completed A user completes a bonus entry task (follow, visit, share, etc.) all_entries_completed A user has completed every available task in the giveaway Payload Format Both webhooks and JS callbacks return the same data for each even
