Is it necessary to include "mkto71_" before every field name? Is there any situation where the "71" should be a different number?

UPDATED - Editing reply because I found a copy/paste mistake in the table and removed it. Data was valid, but a line was missing.

Hi @Alex,​

​

It does look like that's the case, but I'd be very careful with trying to make it a pattern like just adding mkto71 to the API names. The API names do need to be exactly correct in order for them to match up to the original Marketo fields.

Follow the directions in the doc Adding Marketo Fields to Salesforce Enterprise/Unlimited Edition and a video tutorial on how to do it can be found here: Salesforce Connector Setup

When setting the field-level security, the tutorial says to check the box for "read-only" for all profiles but System Administrator. Should my "Marketo Sync" profile also have the read-only box unchecked, so it can write to the lead score field?

If you're using a custom profile, uncheck it for that custom profile. If you're using the Admin profile, you'll want to uncheck it for that profile. Basically, whichever one is responsible for the sync must have write access to the field.

Here's the specifics from the doc Adding Marketo Fields to Salesforce Enterprise/Unlimited Edition

Step 8:

Specify the access settings and click Next:

• Set all profiles to Visible and "Read-Only".
• Uncheck "Read Only" for the profile of your sync user.
• Often customers have a user with the profile of a System Administrator as the sync user. If that's the case with you, then uncheck “Read Only” for the System Administrator profile as shown in the picture below.
• If you have created a custom profile for the sync user, then uncheck "Read-Only" for that custom profile

I followed the video's instructions for setting up the new "Lead Score" field. At the point when it talked about mapping, I noticed there were two "Lead Score fields (one from the MLM package, other from the one I just added) and two "Lead Score" from the contact (again..one installed from MLM and the other from me). Is there a way that I can differentiate between the two? Can I edit the field name to give a visual queue that won't affect anything?

Hi @JB Kuppe​

The most important part is the API names used for these fields you're creating. If you want to alter the friendly name for the old fields that were created by the MLM package, you certainly can.

Does that answer what you were asking about?

Mike

It does, thanks. But I would only be able to alter the fields I'm entering as the MLM package fields are unable to be changed.

As long as you're altering the friendly name/label and not the API names, it should still be ok

Is there any way to sync custom Marketo fields into Salesforce if they were created after the initial sync? I haven't been able to find anything.

Yes, you create the fields in SFDC and then you create a ticket with Support to have them manually map the custom fields together for you. 

**VERY IMPORTANT: whenever you do this, you need to block field updates from SFDC sync in the admin section in field management. 

Why?  Since SFDC is always considered the source of truth, and the new SFDC fields contains all NULL values, it will start Nulling out your Marketo data.  To prevent this from happening, you need to upload all the field data to SFDC first, and then you can re-enable the SFDC sync. 

So steps below

1.  Block Salesforce sync from MArketo fields

2.  Create ticket asking Tech support to map fields

3.  Uplaod data into SFDC fields from MArketo

4.  Re-enable Salesforce sync

Goodluck!
