Waymark / Routes / developer.salesforce.com Use the Salesforce sObject Tree API to insert a parent record and multiple child records in one request

Verified steps Construct a POST request to /services/data/vXX.0/composite/tree/<SObjectType> with a records array Each record in the array may contain a child records block using the relationship name to nest children Assign a referenceId string to every record so the response maps successes and errors back to your payload Submit the request; on success the response contains the new IDs keyed by referenceId On partial failure the entire transaction is rolled back; inspect the hasErrors flag and the results array to identify which referenceId failed Stay within the documented limit of records per call when nesting parent and child objects Known gotchas The entire tree insert is all-or-nothing; a single validation failure rolls back every record in the payload, unlike a standard batch upsert You cannot mix different top-level sObject types in a single tree call; all root records must be the same type Deeply nested trees (grandchildren) are supported but each level must use the correct child relationship name, not the object API name
