}Update membership products
Requires finance_products:write. Partially updates public catalog fields only. Supplied name/description maps replace all translations for that field. Omitted fields are retained. The first update of a legacy product requires defaultLanguage. Changing the default requires that language in every retained non-empty map.

}Authorizations
Public API access token issued by /public/v1/oauth/token. Example: Authorization: Bearer fspt_.... Each resource request rechecks the token company's current provider access. Disabling access blocks existing tokens with 403 auth.provider_unavailable.
Headers
Required for Public API write requests. Reusing the same key with the same method, path, and body replays the stored successful response; reusing it with a different request returns 409 idempotency.conflict.
