Changes to Marketo Salesforce Sync - Overview

Included in this article


Due to changes to the SFDC integration architecture, action is required soon to continue syncing a small number of fields to your Salesforce instance.

Unlike the hundreds of fields that sync between your Marketo and Salesforce instance every day, these fields are set up by deploying a separate “package” on Now, we can directly sync these fields just like the others.

Most customers are only using a couple of these fields in their Salesforce instance – Lead Score and Acquisition Program. However, if your SFDC users rely on any of the 16 fields affected, you’ll need to make some quick modifications to the integration setup.

What’s Happening?

  • Marketo's MLM AppExchange package is being retired. The core Marketo > SFDC sync functionality will remain unchanged.

  • The MLM package itself doesn’t do much, but was responsible for taking 16 fields from Marketo and creating 32 corresponding SFDC fields to sync data into (16 on the Lead object, 16 on the Contact object).

  • The configuration update will shut off the sync of data to the MLM package and these fields, so the data in those fields in SFDC will become stale and won’t update.

  • You can keep syncing the same data to SFDC but it requires creating new custom fields.

  • Once the fields are created, a drip process will be initiated to backfill existing data from Marketo into the new fields in SFDC.

  • The MLM package will be officially deprecated as of January 31st, 2017. The data will stop syncing to the fields created by the MLM package after this date.
