One of my clients does not want the external_id exposed outside Braze and their ecosystem. This value should be exposed in SDK to identify and send events.
Are there any solutions any of you have implemented?
I'm not sure what the client's specific goals are, but perhaps using the SDK Authentication feature(s) will alleviate any concerns they have around security related to external IDs: https://www.braze.com/docs/developer_guide/platform_wide/sdk_authentication/
