WhatsApp Official templates: variables, buttons, and OTP codes.

Variables

Named templates ({{nama}}, {{orderid}}) are filled with an object; numbered templates ({{1}}, {{2}}) with an array, in order.

{
  "channel": "whatsapp_official",
  "to": "6281234567890",
  "type": "template",
  "template": {
    "name": "konfirmasi_pesanan",
    "language": "id",
    "variables": { "nama": "Rina", "orderid": "INV-2207" },
    "button_url": "INV-2207"
  }
}

• header_variables: text header variables.
• media_url: https link for an image, video, or document header.
• button_url: suffix of a dynamic website button link.
• coupon_code: code for the copy coupon button, at most 15 characters.
• language can be left empty when the template exists in only one language.

OTP codes

OTP codes are generated and checked by your system (login, sign-up, checkout). Klik Flow only sends them through an approved Authentication template.

curl -X POST "https://klikflow.id/api/v2/messages" \
  -H "Authorization: Bearer KUNCI_API" \
  -H "Idempotency-Key: 0b8d6c1e-2f4a-4e7b-9c3d-5a6b7c8d9e0f" \
  -H "Content-Type: application/json" \
  -d '{"channel":"whatsapp_official","to":"6281234567890","type":"otp","otp":{"template":"kode_login","code":"482913"}}'

• Codes of 1–15 letters, digits, or - characters.
• The code fills the message text and the Copy code button at the same time.
• Klik Flow does not store the code; in the Inbox and logs it is shown hidden.
• Use a new Idempotency-Key for every new code, so an old code is not sent again.

Template names

Lowercase letters, digits, and underscores, at most 512 characters. Spaces and - in the template builder automatically become _.
