externalAccountId property

String? externalAccountId
getter/setter pair

An optional, immutable identifier that Google uses to refer to this account when communicating with the provider.

This should be the unique account ID within the provider's system (for example, your shop ID in Shopify). If you have multiple accounts with the same provider - for instance, different accounts for various regions — the external_account_id differentiates between them, ensuring accurate linking and integration between Google and the provider. The external account ID must be specified for the campaigns management service type. The external account ID must not be specified for the account aggregation service type. The external account ID is optional / may be specified for all other service types.

Immutable.
