What Is the Crowdfunding & Fundraising Platform Backend Template?

Back4app is a backend-as-a-service (BaaS) for fast product delivery. The Crowdfunding & Fundraising Platform Backend Template is a pre-built schema for users, campaigns, and donations. Connect your preferred frontend (React, Flutter, Next.js, and more) and ship faster.

Overview

A crowdfunding product needs secure management of campaigns, transparent donation processing, and collaboration features.

This template defines User, Campaign, and Donation with secure sharing features and access controls, enabling teams to implement collaboration quickly.

Core Crowdfunding Platform Features

Every technology card in this hub uses the same crowdfunding backend schema with User, Campaign, and Donation.

User management

User class stores username, email, password, and roles.

Campaign management

Campaign class links owner, title, description, and funding goal.

Donation processing

Donation class tracks contributions to campaigns.

Why Build Your Crowdfunding & Fundraising Platform Backend with Back4app?

Back4app provides the necessary primitives for campaign and donation management so your team can focus on engagement and transparency instead of infrastructure.

  • •Campaign and donation management: Campaign class with owner, title, and funding goal, and Donation class to manage contributions.
  • •Secure sharing and visibility features: Manage access to campaigns with permissions, and allow users to donate easily.
  • •Realtime + API flexibility: Use Live Queries for donation updates while keeping REST and GraphQL available for every client.

Build and iterate on crowdfunding features quickly with one backend contract across all platforms.

Core Benefits

Build with AI Agent

Use the Back4app AI Agent to generate a real crowdfunding app from this template, including frontend, backend, auth, and campaign management and donation flows.

Back4app AI Agent
Ready to build
Create a crowdfunding platform app backend on Back4app with this exact schema and behavior.

Schema:
1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system).
2. Campaign: owner (Pointer to User, required), title (String, required), description (String, required), fundingGoal (Number, required); objectId, createdAt, updatedAt (system).
3. Donation: campaignId (Pointer to Campaign, required), amount (Number, required), donor (Pointer to User, required); objectId, createdAt, updatedAt (system).

Security:
- Only the user can update/delete their profile. Only the owner can create/delete their campaigns. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List users, create campaigns, process donations, and manage access.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for user profiles, campaigns, and donations.
