Mapping (1:N Relationships). How to create mapping

Posted on by pentadrian

I'm trying to edit the field mappings in a 1:N relationship. Essentially the relationship is created through an API request for a lookup field and has a single field mapped. What I'm trying to do is query the list of mapped fields and then update that with other fields if needed.

I looked at the AutoMapEntity Action and know how to edit field mappings in a relationship through the UI, but stuck doing it programmatically. Any help would be appreciated!

RE: Mapping (1:N Relationships). How to create mapping

Thank you for the link. I had already explored that and found that the mappings are in entity maps and attribute_maps but the relationship mappings are quite a mess there, with no easy way of querying the metadata short of writing multiple connected queries.

There seems to be the api endpoint for creating a new 1:N relationship (CreateOneToManyRelationship) but that has only a single LookupMetadata field
