REST API reference for developers

Introduction

The Nexus API allows you to programmatically access and manage your workspace data. Build custom integrations, automate workflows, and connect Nexus with your existing tools using our RESTful API.

Authentication

All API requests require authentication using a Bearer token. You can generate an API token from your workspace settings under Settings > Integrations > API Tokens.

Include the token in the Authorization header of every request:

Authorization: Bearer your-api-token-here

Quick Example

Here's a quick example of fetching your projects using curl:

# List all projects in your workspace

curl -X GET https://nexus.app/api/projects \

-H "Authorization: Bearer your-api-token" \

-H "Content-Type: application/json"

Example response:

{

"data": [

{

"id": "proj_abc123",

"name": "Product Launch",

"status": "active",

"created_at": "2026-02-01T12:00:00Z"

}

"total": 1,

"page": 1

}
