With Workflows we could sync Deals fields to Contacts fields if it a Dropdown Field.
We couldn’t sync single-line text fields from Deals fields to Contacts fields.
We also couldn’t sync either of them (single-line text or dropdowns) from Contacts fields to Deals fields until we created external webhooks that were triggered by a field.
@EdgarCerecerez - Were you able to find a solution via Workflows to sync the fields in both Directions. We had to write webhooks to complete this process and I would rather do everything via Workflows.
