How to change rest api name

[Anonymous]

Though I changed the custom variable name - it seems the rest API still uses the name prior to the change. How to change the rest api name.

Hey David,
Amy things rely on API names and changes to these names can make your Marketo instance unstable.

For this reason, it is not possible to change API names of fields.

Instead, we suggest to create a new field with teh correct API name.

Best,
Will

Fine; however, then we would need to be able to delete fields e.g. like these that are now useless.

What to do then?

Thanks ~
