Conducttr allows you to send Notes to Capsule with the Capsule Note content.
For this to work, you'll first need to give your Character a Capsule account.
Add Capsule Account
Your API token in Capsule can be found in My Preferences > API Authentication Tokens.
Please read this Capsule page for more information https://capsulecrm.com/support/integrating-with-other-applications/#locating-your-capsule-api-key
Once the account is setup, you can post Notes in the way you'd post any other content. Look for Capsule Note in the content drop-down.
