Add your API key
Bear this in mind: Your API key is tied to your account. If you’re in a workspace, each person needs to generate their own API key in order to post to Affinity under their account. Here’s how to set it up:- Sign into Affinity at https://www.affinity.co/
-
Click
Settingsin the left navigation, then clickManage Appsunder Developer Tools -
Click the
+ New Appbutton
-
Enter a name for your app (e.g. “Granola”) and optionally add a description, then click
Add App
- An API Key Created modal will appear — copy the key immediately, as you won’t be able to see it again
-
Head to
Settingsin Granola (click your avatar in the bottom left corner of Granola), thenIntegrationsand paste your Affinity API key in the box provided. It will save automatically.
- You’ll now see Affinity appear as a sharing option in a Granola note.
Troubleshooting
-
If you can’t get the integration to connect:
- Check that you’re using the same email address to log in to Granola and Affinity
- Check that you’re using a unique API key, not one generated by another user
- If your Affinity integration was previously connected and has stopped working:
- Error: “Something didn’t work. Check your key or try again.”
