Sender of the Certified Email. It must be a valid email and must have been previously validated in the user control panel.

JSON array with the recipients of the certified email. You can add variables if you want to personalize the Subject and Message per recipient. For example:

                  [
                    {
                        "Nombre": "Pedro Aicart",
                         "Email": "pedro@dominio.com"
                     },
                     {
                         "Nombre": "Ana Aguado",
                         "Email": "ana@empresa.com"
                     }
                  ]

ADVANCED: If you want to protect the notification with OTP, ID document, Certificate, etc.. you must add the following options as variables to each recipient:
PROTECCIONACCESO: It can be:
EMAIL: The system will ask the recipient for the email to which the notification was sent (low protection)
DNI: The recipient will be asked for their ID document to access the notification (You must include the recipient's ID document in the ValorBloqueo variable) (medium protection)
OTP: for protection via OTP, you must indicate the recipient's mobile number in ValorBloqueo (high protection)
CERTIFICADO: The system will ask the recipient to access with their digital certificate or electronic ID document. You must include the recipient's ID document in the ValorBloqueo variable (very high protection)
VALORBLOQUEO: In this variable you must include the blocking value corresponding to the ProteccionAccceso variable.
For example:

                  [
                    {
                        "Nombre": "Pedro Aicart",
                        "Email": "pedro@dominio.com",
                        "ProteccionAcceso": "OTP"
                        "ValorBloqueo": "34601234567"
                     },
                     {
                         "Nombre": "Ana Aguado",
                         "Email": "ana@empresa.com"
                         "ProteccionAcceso": "DNI"
                         "ValorBloqueo": "00000000T"
                     }
                  ]

The subject of the certified email / of the notification

Message that will be sent to the recipient(s)

Date on which the sending is scheduled; the message will be sent on that date. Default "", which means send immediately. Format Year-Month-day hour:minute. The time reference is CET/CEST (Spain time zone).

Parameter used to request explicit acceptance or rejection by the recipient prior to viewing the notification. Options 'SI' or 'NO' (NO by default)

(Mandatory if Acceptance is enabled) It is the time during which the recipient will be able to accept or reject the notification. After this time, if it has not been accepted or rejected, it will expire. Value from 1 to 30 days

JSON array with the attachments if you want to include them in the message. For example :

                  [
                    {
                        "Nombre": "documento.pdf",
                         "Contenido": "JVBERi0xLjcNJeLjz9MNCjg0IDAgb2JqDTw....",
                         "Certificar": "1"
                     },
                     {
                         "Nombre": "otrodocumento.docx",
                         "Contenido": "IyBleHBvcnRlZCBmcm9tIGJhY2ts.....",
                         "Certificar": "1"
                     }
                  ]

Parameter used as a reference for the user. If you choose to receive the report at a URL, you will receive this parameter in the result of the sending.

Type of response to return as the result of the call.
ANT - (Deprecated). Kept for backward compatibility with previous versions
JSON - The response will be returned in JSON
XML - The response will be returned in XML
TXT - The response will be returned in Text format

Sender of the Certified Email. It must be an address validated in your panel, or any mailbox of a corporate domain you have fully validated (for example, if you validated yourdomain.com you can use legal@yourdomain.com, case-2024-0091@yourdomain.com, etc. without validating them one by one).

Name the recipient sees as sender in their inbox (up to 80 characters). In SOBRE mode it also appears in the notice subject.

JSON array with the recipients (up to 1000). Each one gets their own certified email. Only Email is required. Any other field you add (Expediente, Importe, Variable_1...) is a variable you can use in Asunto and Mensaje as {{Field}} (also $$Field$$, ##Field##, [[Field]] or <c>Field</c>).

ACCESS PROTECTION (ProteccionAcceso and ValorBloqueo). Without ProteccionAcceso, anyone who has the email can open the notification. With it, the recipient has to identify themselves before seeing the message and the documents, and every attempt, right or wrong, is recorded in the certificate:

ProteccionAcceso	What the recipient has to do	ValorBloqueo
EMAIL	Type the email address where they received the notification (basic protection).	Not needed.
DNI	Type their national ID (DNI or NIE).	The recipient's DNI or NIE.
OTP	Type a PIN we send by SMS to their mobile at that moment.	The mobile, in international format without '+' (34600000001). If omitted, Telefono is used.
CERTIFICADO	Log in with their digital certificate or electronic ID card, which must belong to the given DNI or NIF (highest protection).	The DNI or NIF of the certificate holder.
PASSWD	Type a password (at most 5 failed attempts every half hour).	The password, 6 to 30 characters without spaces, if you choose it: you can give it to the recipient yourself or ask us to send it (PasswdAcceso). AUTO or no ValorBloqueo: the system generates it, and then PasswdAcceso is required, because only we know it.

If a protection is missing its ValorBloqueo, or it is not valid, the request returns -3 and nothing is sent: an email never goes out without the protection you asked for. Passwords are never returned in the response nor stored in readable form.
For example:

                  [
                    {
                        "Nombre": "Pedro Aicart",
                        "Email": "pedro@domain.com",
                        "Expediente": "2024-0091"
                     },
                     {
                         "Nombre": "Ana Aguado",
                         "Email": "ana@company.com",
                         "Telefono": "34600000002",
                         "ProteccionAcceso": "PASSWD",
                         "ValorBloqueo": "AUTO"
                     },
                     {
                         "Nombre": "Luis Gil",
                         "Email": "luis@company.com",
                         "ProteccionAcceso": "DNI",
                         "ValorBloqueo": "00000000T"
                     }
                  ]

Subject of the notification (up to 150 characters). Supports variables. In DIRECTO mode it is the subject of the email the recipient gets; in SOBRE mode it is shown inside the notice.

Text or HTML of the message (required unless you use Plantilla). Supports variables and the <nocertificar>...</nocertificar> tags (the text between them reaches the recipient but is left out of the certificate).
In DIRECTO mode it is the email body as is: it can be a full HTML with your design. Use {{tablaadjuntos}} to say where the attachment list goes; without it, the list is added at the end. A discreet line with the Secure Verification Code of the certified communication is added at the bottom of the email.

Id of an email template from your panel (the one returned by GetPlantillasEMAIL in the Transactional Email API), instead of Mensaje. Its {{Field}} variables are filled with each recipient's fields and its images are served from our server. As with Mensaje, put {{tablaadjuntos}} in the template to place the attachment list; without it, the list is added at the end.

Scheduled send time. Default: send now. Format Year-Month-Day Hour:Minute, Spanish time (CET/CEST), up to 5 years ahead. With password protection, the password is sent when the email goes out (if you cancel or reschedule the email, the password follows it).

JSON array with the documents: PDF (recommended), images and Microsoft or Open Office documents, in Base64. There is no limit on the number of files: the limit is the size, 20 MB in total per message. Up to 5 MB are included in the 9 credits of the send; each additional MB costs 3 credits. They are always delivered as a list with a download button, never as email attachments. For example:

                  [
                    {
                        "Nombre": "communication.pdf",
                         "Contenido": "JVBERi0xLjcNJeLjz9MNCjg0IDAgb2JqDTw....",
                         "Certificar": 1
                     },
                     {
                         "Nombre": "binding_offer.pdf",
                         "Contenido": "IyBleHBvcnRlZCBmcm9tIGJhY2ts.....",
                         "Certificar": 0
                     }
                  ]

How the recipient sees the notification.
SOBRE (default) - They receive the certified notice with the View message button; opening the content is recorded as a read (the strongest proof of access).
DIRECTO - They receive your HTML (Mensaje or Plantilla) straight in the inbox, with the attachment list. Delivery, opens, clicks and downloads are still certified.

Whether the recipient can reply to the email.
SI (default) - Every reply is recorded as an event (status 14), its attachments are kept in custody (3 credits for each MB of attachments, on arrival) and it is forwarded to REMITENTE or to ReplyTo. On top of the forward we tell you it is the reply to your certified email and, with CadenaRespuestas=SI, that you can answer it as a new certified email. The certification of the reply is included when you answer it or when you request it with CertificarEstadoEMAILCERTIFICADO.
NO - The reply is recorded as an event, but it is not forwarded to you and its attachments are not kept (nothing is charged). The recipient gets an automatic answer (the one in AutoRespuesta or, if you do not set it, a text saying the address does not accept replies). The notice does not invite them to reply.
In both cases, automatic replies from the recipient's mailbox (out of office, ticket system acknowledgements...) are recorded as an interaction (they prove the email is in their mailbox), without being forwarded or charged.

Only with PermitirRespuesta=SI: whether you can answer the recipient's replies as certified emails.
SI (default) - The forward of each reply comes with a reply address of the service. If you answer that email (from REMITENTE or ReplyTo), your answer goes out as a new certified email to the recipient, with the same delivery mode and protection, linked to the previous one: its certificate states which email it answers, and the certificate of the previous email automatically includes the recipient's reply. It is charged as a certified email (only for what you send). To prevent spoofing, answers are only accepted from servers authorised by your domain's SPF; if you have no balance or something fails, we let you know by email and nothing is sent. At most 20 certified answers per conversation and day.
NO - The forward comes with the recipient's address as reply address: if you answer, you write to them directly, without certification.

Domain the certified email is sent from and replies come back to: certificaciones.mensatek.com (default) or buronotificado.com. Reseller accounts send from buronotificado.com.
Your own domain (for example, yourdomain.com): if you have it in the Premium transactional email service, the certified email can be sent from it. The recipients' replies must still reach us so that we record them, keep them in custody and forward them to you, so they come back to a subdomain of yours that points to our servers (for example, notificaciones.yourdomain.com). That is the reply address of the email, on the same domain so that spam filters see it as consistent. We set it up with you when the service is activated: we give you the DNS records to add. If the domain is not Premium, or is not ready yet, the request returns -3 and nothing is sent.
Upper or lower case, either way.

Only with PermitirRespuesta=SI: mailbox replies are forwarded to instead of REMITENTE. It must be validated in your account (or belong to your validated corporate domain).

Only with PermitirRespuesta=NO: automatic answer sent to whoever replies to the notification (once a day per notification, and never to another automatic email such as an out-of-office notice). Fields:
Tipo - HTML or TEXTO.
Asunto - Optional; by default, Re: and the subject of the reply.
Contenido - Text or HTML of the answer (required, up to 20000 characters).
For example: {"Tipo":"HTML","Asunto":"This address does not accept replies","Contenido":"<p>For any query write to support@yourdomain.com</p>"}

To have us send the password to the recipients with ProteccionAcceso=PASSWD, through a channel other than the certified email. It is required if any password is generated by the system (ValorBloqueo AUTO or empty). If you choose all the passwords and do not include PasswdAcceso, we send nothing: you give them to the recipients yourself.
With PasswdAcceso we send it to all the recipients protected with PASSWD. Each one needs the data of at least one of the channels: Telefono (sms, whatsapp, rcs and voz) or EmailPasswd (email). If a recipient lacks the data of a channel, the next one is used; if they have none, the request returns -3 and nothing is sent.
Fields:
Canales - Required. ORDERED list of channels, up to 5 and each type only once: if the first one does not get through, the next one is tried.
sms: Remitente (default: PasswdAcceso.Remitente or your account's) and Mensaje.
whatsapp: IdTelefono and IdPlantilla (an approved template; the password fills its CODE variable).
rcs: IdAgente and IdPlantilla (the template must include the (CODE) variable).
voz: Remitente (one of your active voice numbers), Mensaje and Lenguaje; the password is spelled out.
email: Dominio (your own validated domain, optional), Remitente, Asunto, MensajeEmail or IdPlantilla. Sent to EmailPasswd.
Mensaje - Text for the channels without their own. Write {{PASSWD}} where the password must go. Default (Spanish): Le hemos enviado un email certificado protegido con la contraseña {{PASSWD}}, utilícela para acceder a los documentos protegidos.
Remitente - Sender of the sms channel when the channel does not bring its own.
Longitud - Length of the passwords generated by the system, 6 to 20 (default 8). They use letters and digits, without look-alike characters (O and 0, l and 1).
The password is sent when the email goes out: if scheduled, at the scheduled time; if you cancel it, it is not sent. It is charged according to the channel it goes through.

Asks the recipient to accept or reject the notification before seeing it. SI or NO (default NO). SOBRE mode only.

With Aceptacion=SI: days (1 to 30) the recipient has to accept or reject; afterwards it expires.

Your own reference (up to 60 characters). It is returned in the reports.

Optional, not needed. Real-time reports reach the script you configure in your panel (API configuration).
