Getting API Credentials

1. Create an Upwork App:

   • Go to Upwork Developers
   • Create a new app to get your API Key and Secret
   • Request API access if you haven't already

2. OAuth 2.0 Flow:

   • Use the API Key and Secret to initiate OAuth 2.0 flow
   • Get the Access Token after user authorization
   • Store the Access Token securely

Environment Variables

No environment variables are required! OAuth tokens are automatically fetched from AWS Secrets Manager.

AWS Secrets Manager Setup

The server expects OAuth tokens to be stored in AWS Secrets Manager:

1. Secret Names:

   • upwork-oauth-tokens - Freelancer account tokens
   • upwork-oauth-tokens-agency - Agency account tokens (optional)

2. Secret Format:

   {
     "access_token": "...",
     "refresh_token": "...",
     "expires_in": 86400,
     "token_type": "Bearer",
     "obtained_at": "2024-..."
   }

3. AWS Region: us-east-1

4. External Token Management: Token refresh is handled by your external Lambda function
