Campaign APIs

Overview

The Witness Chain Campaign APIs provide developers with powerful tools for requesting tasks and observations in the real world. They work in conjunction with the InfinityWatch app, which acts as a portal to the physical world. These APIs enable developers and organizations to crowdsource authentic, geoverified photographs by launching campaigns on the InfinityWatch app and rewarding participants through a gamified system.

Key Features

Location Verification

• Create geofenced campaigns that only accept tasks and observations from specific geographic areas

• Capture observations via a trusted camera integrated into the InfinityWatch app

• Define custom radius boundaries for photo submissions

• Ensure observations are captured at the claimed location and time through built-in verification utilizing Witness Chain's PoL (Proof of Location) network

Reward System (COMING SOON)

• Implement campaign points for successful photo submissions

• Set custom campaign points per task

• Define campaign-wide campaign point pool

• Track and manage fuel consumption for user activities

Campaign Management

• Create individual, group, or task-based campaigns

• Set campaign duration with start and end dates

• Control submission limits

• Add rich media content (banners and posters) to campaigns

• Tag and categorize campaigns for better organization

Use Cases

Campaigns enable your code to actuate and observe the physical world. This has applications for all use cases that need on-the-ground operations.

1. Verifiable News

   1. Request observations - verified photos - at local news hotspots

   2. Discover new local events

   3. Gather and summarize the latest intelligence on events happening near you

2. Real community engagement and incentivization

   1. Request communities to attest their physical attributes

   2. Prevent farmers and Sybil attacks

   3. Ensure fair incentive distribution with custom policies

3. Infrastructure expansion and monitoring

   1. Incentivize new infrastructure deployment

   2. Track deployment progress

   3. Monitor maintenance needs

   4. Document facility conditions

4. Marketing campaigns

   1. Collect authentic user-generated content

   2. Verify in-store promotions

   3. Document brand activations

5. Community Engagement

   • Organize local clean-up documentation

   • Create neighborhood improvement initiatives

   • Run citizen journalism projects

Getting Started

To begin using the Campaign APIs:

1. Please fill out this form for early developer access to the API and the app

2. Complete the authentication flow using pre-login and login endpoints

3. Create a campaign with specific geographic boundaries

4. Set reward parameters to incentivize participation

5. Monitor and collect verified photo submissions

Implementation Flow

1. Authentication

   • Secure your API access through two-step authentication

   • Maintain session tokens for continuous operation

2. Campaign Creation

   • Define campaign parameters

   • Set geographic boundaries

   • Configure reward structure

3. Photo Collection

   • Receive location-verified submissions

   • Track campaign progress

4. Campaign Management (COMING SOON)

   • Reward campaign points

   • Monitor submission rates

   • Adjust campaign parameters as needed

   • Access submission data and analytics

Best Practices

1. Geographic Targeting

   • Set appropriate radius boundaries based on campaign needs

   • Consider population density when defining target areas

   • Use recommended coordinate precision for accurate location verification

2. Reward Structure

   • Balance campaign point amounts with the campaign budget

   • Consider task complexity when setting campaign points

   • Implement fair fuel consumption rates

3. Campaign Duration

   • Set realistic timeframes for photo collection

   • Consider seasonal factors affecting outdoor photography

   • Plan for peak participation periods

4. User Experience

   • Provide clear campaign descriptions

   • Use high-quality campaign banners and posters

   • Set achievable submission targets

Technical Considerations

• All API endpoints require authentication

• Implement proper error handling for geographic verification

• Cache authentication tokens appropriately

• Monitor campaign points pool consumption

• Handle timezone differences in campaign scheduling

The Campaign APIs provide a robust foundation for building location-aware photo collection systems while maintaining data integrity through verification mechanisms. Whether you're building a community engagement platform or a marketing campaign tool, these APIs offer the flexibility and features needed for successful implementation.
