Delete Records Using sObject Rows by External ID

For security reasons, some Top Level Domains (TLD) can conflict with certain file format extensions. Adjust your implementation to work around such cases.

For example, using an email address, such as example@email.inc, as the External ID returns a “404 not found” error.

There are several workarounds to handle conflicting TLDs.

• Use a different External ID field.
• Create a new External ID field that is the same as the email field and replace the "." with an "_" to handle this case.
• Run a query for emails ending in ".inc" to retrieve the record ID and use that for the upsert request.
• Use SOAP API instead of REST API for upsert requests.
• Accept the email as a query parameter instead of a path parameter by creating a custom Apex REST API. Use Apex to perform the upsert request.
