Before Creating a Schema
Connect to Your Airtable Account
Note: Once a Schema is created and connected to a base, you cannot change which base is being used for that particular Schema. You will need to create a new Schema to connect to a different base.
Schema Source Types
There are three ways to set up a Schema for your Airtable base - API, Script, or Block
API
With this option, all the setup is done in the On2Air dashboard without having to add anything to your Airtable base. The API Source option uses the Airtable API to connect with your base and generate a Schema. The limitation with this option is you cannot view how relationships are connected.
Benefits
Can view every base, table, view, or field change, such as a name change, a field type change, or any deleted items
See a before and after of every change
Create multiple snapshots of your schema for backups
Share a public version of your schema
Create a print layout of your schema
Can use on Free, Plus, or Pro Airtable accounts
No setup required inside Airtable
All setup is done in On2Air: Schemas dashboard
Limitations
Limited ability to view all changes due to restrictions in the Airtable API
You can view Relationship fields in the Schema, but cannot view how Relationships are connected
Script
The Script Source option uses a generated script code from On2Air to paste into the Airtable Scripting App. It’s simple to create and add the code into your base (no coding experience required!)
Benefits
View and highlight all Relationship connections
Can view every base, table, view, or field change, such as a name change, a field type change, or any deleted items
See a before and after of every change
Create multiple snapshots of your schema for backups
Share a public version of your schema

Can use on Free, Plus, or Pro Airtable accounts (Free and Plus until March 2021)
