Why Isn't My Marketo Custom Field Available as a Sync Key?
Question
Why can't I select a Marketo custom object field as the sync key for my Marketo sync?
Environment
Activations destination: Marketo
Answer
You can't select a Marketo custom object field as a sync key unless it's configured to prevent duplicate records. To make the field available:
In Adobe, mark the field as a Dedupe Field. For instructions, see the Adobe Adobe Add Marketo Custom Object Fields documentation.
In Fivetran, refresh the available sync keys:
i. Go to the relevant Activation sync page.
ii. In the top right, select the more options menu, then click Edit.
iii. In the Select a Sync Key section, click Refresh Fields.
iv. In the Choose a field in... drop-down menu, select the custom object field.
For more information on Fivetran's supported sync key field types, see the Marketo destination documentation.
