HubSpot's built in blog migration tools don't currently support migrating author bios or profile images so I built this tool just for this purpose. This tool assumes the authors have already been migrated into HubSpot and it only syncs the bio and avatar. Feel free to adjust as needed for your purposes.
Run npm install to install the 2 dependencies. Then, create a .env file by cloning the example file and updating the HUBSPOT_TOKEN with your access token and adding the your WordPress URL to the WORDPRESS_URL. Finally, create an application password inside WordPress via an admin account and add those credentials to the .env file as well.
Now, you should be able to run the script via npm run start and it will sync the data, woot!
