GET /v1/projects/{id}/platforms/whatsapp-business/signup-config Returns what the browser needs to open Meta’s Embedded Signup popup: the Facebook Login for Business configuration id, the Graph version to run against, and the scopes it will request. Answered in-process rather than forwarded, so the first step of onboarding survives an outage of the private service. Pass configId to FB.login as config_id with response_type: 'code' and override_default_response_type: true. Do NOT add a featureType — omitting it is what keeps the phone-number screen in the flow, and only_waba_sharing produces an account with no number that cannot be provisioned. Requires the platforms:read permission bound to the project resource in the path.
