This appears to be related to a managed package from roundCause Giving: roundcorner.screenstepslive.com/s/roundCause_Documentation/m/8404/c/52649.Based on the error message, it appears to be related to a Contact update, not to an "Add to Campaign" event.

You can however use the regular "Get Activities" API and pass in a List ID. Just create a Smart Campaign in each Partition that adds all Person records in that Partition to a designated Static List.

Sanford's approach uses the primaryAttributeValue, assuming the Email lives inside the Program and assuming there are no periods in the Program or Email name. You can also consider this approach: https://nation.marketo.com/thread/50537-api-questions-engagement-programs-activity

Unfortunately there is nothing that can be done about that limitation: the 10Mb limit is hard. If you are going the custom route, maybe upload files > 10Mb to a public S3 bucket (or other file hosting service) and save the URL in a Marketo Program Token or "My Token" on a Marketing Activities Folder...

The maximum file size for file uploads via the REST API is 10 Mb. So unfortunately you will have to upload those files manually via the UI. Files up to 10 Mb should upload with no issue.

Chris Wilcox Yes, it is disappointing that this feature doesn't work in Sales Insight. I do believe it's also possible to create a JavaScript button on the Lightning List view, but honestly I don't have that working myself yet. After I left Marketo I have been working on a customizable solution for ...

Not true. You can still send individual emails. However, in Classic you could send up to 200 emails at a time from the List view: that doesn't work with Sales Insight on Lightning. See the list of limitations on the bottom of this page: https://docs.marketo.com/display/public/DOCS/Salesforce+Lightni...

The fastest solution is to recreated it with a different API name, but same Display Name. However, it is supposed to be permanently deleted, so - if you have a bit more time - I would open a support ticket so one of the support engineers can investigate.

If you just want to see which records were added to the List in a particular time frame, you can create a Smart List with the "Was Added to List" filter and specify a time frame. If you want to see the dates when records were added to the list, you'll need to extract the activities via the REST API ...

Hard to answer that without seeing the setup. I would open a support ticket.
