Hi Guys,
We have a list of client data (list with their lead.id) and want to update a custom field of these clients. I learned that we cannot import a file with just lead.id to update the data fields.
However, we can create an API call to update the existing record with lead.id. can some please share a sample API call for this?
Thanks!

Hello,
I think you should use the endpoint /rest/v1/leads.json and build the body of the message to update the fields you want. In this link there is an example:
https://developers.marketo.com/rest-api/lead-database/leads/
It is important to correctly define the action ("createOrUpdate", "createOnly" or "updateOnly). In this case I'd recommend you to use the "updateOnly", otherwise marketo will create a new lead if it doesn't find the lead you want to update. Also choose "id" as your "lookupField" so it will query the lead with same lead id.
When I first used this API I was working with a instance that had many partitions and I wasn't being able to find the right lead to update. If this is your case use the "partitionName" attribute to choose the right partition your leads are in.
