Identifiers
Details on how your internal identifiers are ingested and managed by Flex.
When ingesting data, you are responsible for selecting a external identifier (your internal identifier) for the various entities. Typically, this is a guid, but can be any other identifier.
These identifiers are usually referenced as an ext_id in payloads to Flex.
Identifiers must be less than 37 characters, and must be unique for the given entity type.
When ingesting associated data (say a transaction for a customer), the customer ext_id on the transaction entity should match the ext_id value used when the customer was ingested.
Please ensure that you do not use a personal identity number as the external identifier for customers.
⚠️ Please select identifiers carefully. Once ingested, they should be treated as immutable for a given entity.
