Explanation

Querying relationship metadata Entity relationships can be queried using the RelationshipDefinitions entity set. You can use a query like the following to get the SchemaName property for every relationship. GET [Organization URI]/api/data/v9.0/RelationshipDefinitions?$select=SchemaName The properties available when querying this entity set are limited to those in the RelationshipMetadataBase EntityType. Note: You can retrieve relationship metadata in the context of a given entity much in the same way that you can query attributes. The ManyToManyRelationships, ManyToOneRelationships, and OneToManyRelationships collection-valued navigation properties can be queried just like the Attributes collection-valued navigation property. However, entity relationships can also be queried using the RelationshipDefinitions entity set. https://docs.microsoft.com/en-us/power-apps/developer/data-platform/webapi/query-metadata- https://docs.microsoft.com/en-us/power-apps/developer/data- platform/webapi/reference/relationshipmetadatabase?view=dataverse-latest
