SFDC Syncing Issues

  • March 2, 2026

I have a client that is letting me know that the sync between Marketo engage and SFDC reports some errors leaving the leads with empty fields on SFDC, so she's unable to assign them to the sales team. What I don’t understand is how is it possible the leads get synced in SFDC when those fields are marked as mandatory to fill on the forms on LPs in Marketo. Anyone experienced any similar discrepancy in this process?

    ​@MartaOr1, In addition to checking write access (which is important), there are a few common reasons this can happen, even when the fields are mandatory on Marketo forms:

    1. If the person is created via List import, API, Salesforce sync (created in SFDC first), or another integration, the Marketo form validation never runs. “Required” only applies to that specific form submission, not to the database globally.
    2. Also, as mentioned earlier, if the Marketo sync user doesn’t have edit access to the field(s) in question/field visibility, Marketo can create a lead in Salesforce, but fail to populate specific fields.
    3. It could also be a case where fields populated with valid values through form fillout are overwritten by a flow in a Smart Campaign. Worth checking the Data Value Change history on a sample record.

    I hope this is helpful. Pls let us know how your troubleshooting goes and/or if you have any more questions.

    Does Marketo have write access to those fields in SFDC?

    How can I see it?

    Hi ​@MartaOr1 - You can see if the field is sync’ed to SFDC in the field manager in Marketo admin section.  If you see it there then to confirm write access in SFDC you would need to look at the permission set of the Marketo integration user in SFDC.  I’d reach out to your SFDC admin on that if you don’t have direct access.
