PATCH /accounts/external-ids Bulk writes your system’s external IDs into existing Recotap accounts, matched by domain. Max 100 mappings per request. Designed for the initial ID backfill. Use List Unmapped Accounts first to identify which accounts need IDs, then call this endpoint to write them all in one pass.
Request body Mapping object Response data
Existing externalId values are overwritten without warning. If the same domain appears more than once in the request, the last mapping takes precedence.
