Account lookup by external ID

You can load an Account with identifiers your business systems already use, so integrations do not need to store or sync internal UUIDs.

• Register namespace and value pairs in externalIds when you create or update the Account profile, so the same identifiers work on every lookup.
• Fetch Account details by passing ext:{namespace}:{identifier} where you would otherwise use the internal Account ID, instead of resolving the UUID first.
• CRM, billing, and provisioning tools can keep their own merchant or location codes while still calling Authvia APIs reliably.
