The Persona API accepts requests with attribute keys using camelCase, kebab-case, and snake_case.
All responses use kebab-case for attribute keys by default. However, you can override how attribute keys are formatted by providing an additional Key-Inflection: <inflection> header to the request. The Persona API currently accepts kebab, camel, and snake for inflecting keys. You can also set the default key inflection on the API key itself via the Persona dashboard.
Incoming requests from webhooks are also key inflected according to the default key inflection setting on the Webhook.
