## TL;DR

It never changes for this user. Later profile edits arrive as user.updated, so refresh on that event instead of caching this one forever. - Return 200 only after your row exists.

## Steps

1. Take the Clerk id from `evt.data.id`. Store it as your external user key. It never changes for this user.
2. Find the primary email: read `evt.data.primary_email_address_id`, then pick the entry in `evt.data.email_addresses` whose `id` matches it. Do NOT assume `email_addresses[0]` is primary. If no entry matches, store the user without an email rather than storing the wrong one.
3. Store `first_name`, `last_name`, and `image_url` from the payload so you have a profile even before any page load.
4. Copy `public_metadata` into your record if you gate features on it. Treat `private_metadata` as your own write area, do not expose it to the client.
5. Return 200.

2. - Upsert, never insert blind. Retried deliveries and replays will send this event twice.
- The payload is a snapshot at creation time. Later profile edits arrive as `user.updated`, so refresh on that event instead of caching this one forever.
- Return 200 only after your row exists. A 5xx tells Clerk to retry, which is safe only if step 1 is an upsert.

## When to use

You are seeing this: Fires once per user, when the user object is first created in Clerk. Use this skill when you run into "Clerk event: user.created, create the local record and never guess the primary email".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
