The Update Record REST API updates the specified root record and its child records. Send the ID of the record in the request URL. Send the summary of the changes in the body of the request.
After the change, if the record is in a pending state, use the Promote API to promote the changes. For example, if the update triggered a review workflow, the record is in a pending state until the review is complete.
The API uses the POST method.
For root records, you can choose to use the simplified PUT version, where the body of the request contains the changed field, not a change summary. To update root records and related child or grandchild records, use the POST version. You also have the option to use the PUT version with the PKEY or the specify the rowidObject of the child record.
