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

-
Head to

- You’ll now see Affinity appear as a sharing option in a Granola note.
Share notes to Affinity
Once connected, you can share any note to Affinity by clicking the Affinity option in the top right of the note. Granola will suggest matching People and Company records based on the email addresses of meeting attendees from your calendar event. You can review the suggestions, remove any you don’t want, or search for additional records before saving.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.”
