Request Fields

Send the request as application/json.

Field	Type	Required	Validation
trId	string	Yes	1–36 characters; letters, digits, and hyphens only.
ktp	string	Yes	Raw Base64-encoded JPEG, JPG, or PNG image; decoded size at most 4 MB.

Code
{
  "trId": "ktp-ocr-001",
  "ktp": "/9j/4AAQSkZJRgABAQAAAQABAAD..."
}

Send the Base64 value without a data:image/...;base64, prefix. KTP OCR API v2 validates the Base64 data, decoded file size, and detected image type. It does not apply a documented pixel-dimension requirement.

Additional detection, blur, orientation, and NIK checks may run when enabled for your integration.
