How to Use Postproxy

Create a Postproxy Account: Visit postproxy.dev and create an account to get started. No platform-specific setup is required initially.

Generate API Key: Once your account is created, generate an API key that will be used to authenticate your requests to the Postproxy API.

Link Social Media Accounts: Connect the social media accounts (Twitter, LinkedIn, Facebook, Instagram, YouTube, Threads, TikTok) that you want to publish to through Postproxy.

Integrate the API: Choose your integration method: REST API, n8n community node, or MCP server for AI agents. For basic REST API usage, use the endpoint https://api.postproxy.dev/api/posts

Make Your First Post: Send a POST request to the API with your content. Include your API key in the Authorization header and specify the content and target platforms in the request body. Example: curl -X POST 'https://api.postproxy.dev/api/posts' -H 'Authorization: Bearer YOUR_API_KEY' -H 'Content-Type: application/json' -d '{"post": {"body": "Hello World!"}, "profiles": ["facebook", "instagram"], "media": ["https://example.com/image.jpg"]}'
