Field compatibility

Understanding why certain fields are not compatible and cannot be synced

Why fields must be compatible

When syncing, you must map "compatible fields" so that Whalesync can translate data between your apps. In this translation, Whalesync handles much of the heavy lifting (like converting HTML to Markdown), but ultimately the data in these fields needs to work with each other.

Understanding reference fields

One of the more advanced field types to map are "relation fields" (aka "reference fields", "linked records", or "foreign keys"). These are fields that have a relation to another table.

Relation fields must be mapped to other relation fields in order to sync.

How to find fields that are compatible with reference fields

• If you're unsure how to create relation fields in your apps, check our docs on relation fields.
• In general, look for the squiggly arrow icon indicating a relation field (see screenshot above).
