Harvest

Prefer guided AI setup?

Instead of following these steps manually, you can use the AI Credential Assistant — describe what you want to connect and the AI will walk you through the setup step by step, tailored to your account.

Overview​

Connect your Harvest account to Nirvai to automate time tracking, project management, and invoicing workflows.

Supported Authentication Methods​

  • Personal Access Token (Bearer)

Prerequisites​

  • A Harvest account
  • Access to Developer settings

Setup Instructions​

Personal Access Token Authentication​

  1. Log into your Harvest account
  2. Go to Developers in your account settings
  3. Navigate to Personal Access Tokens
  4. Click Create New Personal Access Token
  5. Give your token a name (e.g., "Nirvai Integration")
  6. Copy the generated token immediately (it won't be shown again)
  7. In Nirvai, paste the token in the "Bearer Token" field

Important Notes​

  • Personal Access Tokens provide full access to your Harvest account
  • Tokens are shown only once upon creation - save them securely
  • You can revoke tokens at any time from the Developer settings
  • OAuth2 is also available for more advanced integrations

Troubleshooting​

Common Issues​

  • Token not working: Ensure you copied the full token without truncation
  • Access denied: Verify the token hasn't been revoked
  • Expired token: Personal Access Tokens don't expire, but can be manually revoked
