Each pair of Data Link Table and Connection will have a separate Data Link Table Instance.

You can find all the Data Link Table Instances on the Instances page.
If you click on a given Data Link Instance, you can see and modify the list of Data Links in that instance.

Whenever you create a link from one record to another, it is recorded in a corresponding Data Link Table Instance.

Data Links

A Data Link is a record within a Data Link Table Instance that has:

externalRecordId – id of a record on the external app's side.
appRecordId – id of a record on your app's side.
direction – one of:
- export – link from your app to an external app.
- import – link from external app to your app.

Creating Data Link

A Data Link is created with the following data:

dataLinkTableInstanceId – id of Data Link Table Instance associated with the record
externalRecordId
appRecordId
direction – export, import, or both.

If direction both is selected then both export and import links will be created.

Only one link with the same externalRecordId, appRecordId, and direction can exist within a single Data Link Table Instance. If another one is created, it will overwrite the previously existing one.

Finding Data Link

When finding a data link with a Flow Node or a Formula, you need to provide:

dataLinkTableInstanceId
direction
recordId

Find External Record Id and Find App Record Id formulas provide direction automatically.
