activationMethod: "LINK" to activate via a hosted-page link instead of OTP. The end-user receives an email link and completes activation by consenting on the hosted page, after which the link is single-use. On success the merchant moves to PENDING_ACTIVATION. For LINK the response returns activationMethod and linkExpiresAt (72-hour TTL) instead of the OTP-specific fields; supportContactEmail and showPartnerLogo configure the activation email and apply to both OTP and LINK. Re-initiating with LINK supersedes any previous link.activationStatus value differs by channel: OTP reports MerchantActivationStatus (NOT_ACTIVATED / PENDING_ACTIVATION / ACTIVATED / LOCKED / EXPIRED / NO_NEED_ACTIVATION), while LINK reports LinkActivationStatus (PENDING_ACTIVATION / ACTIVATED / EXPIRED / NO_NEED_ACTIVATION / INVALIDATED).
