Anthropic has disabled 3rd party authentication for their OAuth. In order to continue supporting Anthropic based models in OpenWork, we now default to manual API key entry for Anthropic. That means you create the key in Anthropic first, then paste it into OpenWork.

​
Before you start

  • You need an Anthropic account at platform.claude.com.
  • Your Claude subscription and your Anthropic API billing are not always the same thing, so make sure API access is enabled on your Anthropic account.
  • Treat the key like a password. Anthropic will only show the full value when you create it.
If this key should be shared across a team, add Anthropic once in OpenWork Cloud LLM Providers and import it from Settings -> Cloud instead of pasting it into each workspace separately.

​
Create the key in Anthropic

  1. Sign in at platform.claude.com.
  2. Open the API Keys page.

  1. Click Create Key.
  2. Give the key a recognizable name like OpenWork.

  1. Copy the new key right away. It should look like sk-ant-....

​
Add the key to OpenWork

  1. Open Settings in OpenWork.
  2. Go to Connect Provider and choose Anthropic.
  3. Paste the API key into the manual key field.
  4. Save the provider, then choose an Anthropic model in chat.

Common issues

  • If the key is rejected, make sure you copied the full value without extra spaces.
  • If you cannot see API Keys, check that your Anthropic account has API access and billing set up.
  • If you lose the key, create a new one in Anthropic and update OpenWork with the new value.
The same general process applies to most providers that use manual API keys: create the key in the provider’s developer console, copy it once, and paste it into OpenWork.
