Marketo API - How to create custom fields?

[ernie]

Hello marketo community! 

Using the interface, one can create new custom fields. More specifically via --> Admin --> Lead Management --> Create new custom field -> and filling out the required information on the pop-up and hitting save.

Now, let's say that you have a list of 40 custom fields that you need to create, and that you have to do this every once in a while. 

How can one automate this process via the Marketo API? Is it even possible to create custom fields via the API? 

I checked the docs and could only find information on how to update a custom field (https://developers.marketo.com/blog/create-a-custom-field-in-marketo-and-update-this-field-via-api/). 

But I cannot find any info in the docs, or in the Marketo community on how to create custom fields via the API.

Any help would be much appreciated!

Best, Ernie

Hello @ernie ,

I do not see that as an option here:  https://developers.marketo.com/rest-api/endpoint-reference/endpoint-index/

It looks like you can for custom objects but not the standard objects.

End point:   /rest/v1/customobjects/schema/{apiName}/addField.json

Hi @Oz_Platero 

Thanks for your comment! 

I double checked the endpont-index, and there is no reference to creating custom lead fields via the API.

So it seems like it's not currently possible. 

Have a good one!
