Influencer Portal Backend

Influencer Portal App Backend Template
Manage Influencer Outreach and Performance Data

Q: What is an Influencer Portal backend?

An Influencer Portal backend is a BaaS schema and API for influencer management: influencers, contracts, posts, and performance data.

Q: What does the Influencer Portal template include?

It includes Influencer (name, email, social profiles), Contract (influencer, brand, status), Post (influencer, content, performance), and Performance (post, metrics), ER diagram, API playground, and an AI Agent prompt.

Q: Why use Back4app for an influencer management app?

Back4app provides managed database, auth, real-time queries, and flexible schema so you can ship influencer engagement, contract flows, and performance tracking without running your own backend.

Q: How do I run queries for influencers and contracts with Flutter?

Use the Influencer and Contract classes to query and display profiles and agreements, leveraging the Back4app SDK.

Q: How do I create a contract with Next.js server actions?

Use a server action to create a Parse Object for Contract with influencer pointers and status. Optionally validate in Cloud Code.

Q: Can React Native cache influencers and posts offline?

Yes. Enable Local Datastore and pin Influencer and Post results so users can browse saved profiles and content without connectivity.

Q: How do I prevent duplicate contracts?

In Cloud Code beforeSave for Contract, query existing contracts and reject if a duplicate exists.

Q: What is the best way to show influencer profiles and posts on Android?

Query Influencer and Post classes to display profiles and content, using the Back4app SDK for data management.

Q: How does the performance tracking flow work end-to-end?

Influencers can track performance metrics for each post, and the system updates in real-time using Live Queries for instant notifications.

Influencer profiles and contracts

Influencer class stores name, email, social profiles, and contracts.

Contract creation and management

Contract class links influencer, brand, and status.

Post creation and performance

Post class stores influencer, content, and performance metrics.

Performance tracking

Performance class tracks post metrics and engagement.

Why Build Your Influencer Portal Backend with Back4app?

Build with AI Agent

Use the Back4app AI Agent to generate a real Influencer Portal app from this template, including frontend, backend, auth, and influencer, contract, post, and performance flows.

Back4app AI Agent

Ready to build

Create an influencer management app backend on Back4app with this exact schema and behavior.

Schema:
1. Influencer (use Back4app built-in): name, email, social profiles; objectId, createdAt, updatedAt (system).
2. Contract: influencer (Pointer to Influencer, required), brand (String, required), status (String: pending, active, completed, required); objectId, createdAt, updatedAt (system).
3. Post: influencer (Pointer to Influencer, required), content (String, required), performance (Pointer to Performance); objectId, createdAt, updatedAt (system).
4. Performance: post (Pointer to Post, required), metrics (Object, required); objectId, createdAt, updatedAt (system).

Security:
- Only the influencer can update/delete their profile. Only the author can create/delete their posts and performance data. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List influencers, create contracts, post content, track performance, and manage agreements.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for influencer profiles, contracts, posts, and performance tracking.
