Is a custom field API Name editable?

[Anonymous]

We are integrating a custom field with our company product dashboard, and pushing information from the dashboard to the Marketo field. I labeled the API Name "Current_product_name" and our team has now let me know that the script is being pushed to "Current_Product_Name". This is kind of a two part question - 1. Does the capitalization matter, and if so, 2. Is there a way to edit this?

I've tried to create another field with the capitalized API Name, but Marketo will not allow me to do so because it says that the API Name is already taken. Would love to get some assistance here!

Hi Michael,

Field API name is not case sensitive, so it would work in your script.

If your field only lives in Marketo then NO you can not edit field API name.

If your field was created in SF then you can directly do it from there and Marketo will push the updates in the instance.

Thanks

API names are strictly case sensitive in Marketo.

What about characters? Can the API name contain an underscore?

Example --> Custom field = mm_country

When Marketo auto fills in the field during the custom field creation, the underscore is removed --> mmcountry

Hello

When creating utm:
UTM-SOURCE
UTM-MEDIUM
UTM-TERM
UTM-CONTENT
UTM-CAMPAIGN

I have to fill in the type / Api name fields.

I don't have that information.

Could you help me ?

Thank you

API names are not editable.  If you cannot use an alternative name, then support will need to remove this for you so you can create a new field.
