Section titled “Request Bodyrequired”Email address to verify

The browser’s anonymous PostHog distinct_id. The emailed verification link usually opens in a different browser context, so completion uses this to merge the original context’s analytics identity into the new user.
Meta click ID.
Google Ads web-to-app click ID.
Google Ads click ID.
First-touch referrer host captured on landing (e.g. “google.com”).
Google Ads app-to-web click ID.

Error response. error.type is the machine-readable code — branch on it, never on error.message or the HTTP status. error.message is display-grade prose safe to render to a user; when a failure has no specific copy it falls back to a generic sentence, so it never carries a machine code. Unrecognised failures collapse to the generic unprocessable_entity code, so treat type as an open enum: match the codes you handle and fall through to a default branch for the rest.
