To add Upwork tracking integration, click +Add Integration and select Upwork as the provider.

Next, authorize via Upwork by clicking the Connect Upwork button.

After successful authorization, a dropdown list of accounts will appear in the Account field.

To make the integration work for Cloud clients, we use our own app and our Client ID (similar to an API key).

For self-hosted clients, you need to first generate your own API key by following the instructions.

Then, you can also contact ITFin support for help.
