Since yesterday I've been trying to pass parameters through the SendInBlue API but it just doesn't work. I've tried everything. I've seen many code examples, but unfortunately it doesn't work.

I even used as an example the code in C# that they put on their website and it still doesn't work.

Follow my code:

using System.Diagnostics;
using System.Net.Http.Headers;
using Newtonsoft.Json.Linq;
using sib_api_v3_sdk.Api;
using sib_api_v3_sdk.Client;
using sib_api_v3_sdk.Model;
using Task = System.Threading.Tasks.Task;

namespace cjuridico.Domain.Models.Email;

public static class CadastroEmail
{
    public static async Task EnviarEmail(string destinatario, string mensagem)
    {
        Configuration.Default.AddApiKey("api-key", "<omitted>");
        var apiInstance = new TransactionalEmailsApi();
            string SenderName = "John Doe";
            string SenderEmail = "example@example.com";
            SendSmtpEmailSender Email = new SendSmtpEmailSender(SenderName, SenderEmail);
            string ToEmail = "mataveli91@gmail.com";
            string ToName = "Guilherme Vianna";
            SendSmtpEmailTo smtpEmailTo = new SendSmtpEmailTo(ToEmail, ToName);
            List<SendSmtpEmailTo> To = new List<SendSmtpEmailTo>();
            To.Add(smtpEmailTo);
            string BccName = "Janice Doe";
            string BccEmail = "example2@example2.com";
            SendSmtpEmailBcc BccData = new SendSmtpEmailBcc(BccEmail, BccName);
            List<SendSmtpEmailBcc> Bcc = new List<SendSmtpEmailBcc>();
            Bcc.Add(BccData);
            string CcName = "John Doe";
            string CcEmail = "example3@example2.com";
            SendSmtpEmailCc CcData = new SendSmtpEmailCc(CcEmail, CcName);
            List<SendSmtpEmailCc> Cc = new List<SendSmtpEmailCc>();
            Cc.Add(CcData);
            string HtmlContent = "<html><body><h1>This is my first transactional email {{params.parameter}}</h1></body></html>";
            string TextContent = null;
            string Subject = "My {{params.subject}}";
            string ReplyToName = "John Doe";
            string ReplyToEmail = "replyto@domain.com";
            SendSmtpEmailReplyTo ReplyTo = new SendSmtpEmailReplyTo(ReplyToEmail, ReplyToName);
            string AttachmentUrl = null;
            string stringInBase64 = "aGVsbG8gdGhpcyBpcyB0ZXN0";
            byte[] Content = System.Convert.FromBase64String(stringInBase64);
            string AttachmentName = "test.txt";
            SendSmtpEmailAttachment AttachmentContent = new SendSmtpEmailAttachment(AttachmentUrl, Content, AttachmentName);
            List<SendSmtpEmailAttachment> Attachment = new List<SendSmtpEmailAttachment>();
            Attachment.Add(AttachmentContent);
            JObject Headers = new JObject();
            Headers.Add("Some-Custom-Name", "unique-id-1234");

            Params.Add("SENHA", "Guilherme");
            List<string> Tags = new List<string>();
            Tags.Add("mytag");
            SendSmtpEmailTo1 smtpEmailTo1 = new SendSmtpEmailTo1(ToEmail, ToName);
            List<SendSmtpEmailTo1> To1 = new List<SendSmtpEmailTo1>();
            To1.Add(smtpEmailTo1);
            Dictionary<string, object> _parmas = new Dictionary<string, object>();
            _parmas.Add("params", Params);
            SendSmtpEmailReplyTo1 ReplyTo1 = new SendSmtpEmailReplyTo1(ReplyToEmail, ReplyToName);
            SendSmtpEmailMessageVersions messageVersion = new SendSmtpEmailMessageVersions(To1, _parmas, Bcc, Cc, ReplyTo1, Subject);

                Debug.WriteLine(e.Message);
                Console.WriteLine(e.Message);
                Console.ReadLine();
            }
        }
    }

I recently encountered the same problem while working with my PHP code. Initially, I assumed it was due to a mistake in my code. However, I later discovered that the issue was with my template. Specifically, if you have defined {{ first_name }} in your template, simply replace it with {{ params.first_name }} and your email will begin to display the value of the parameters that were sent through the API call.

  • Thank you. For some reason their documentation is not well organised and I missed that part. – VPetrovic Jul 28 '23 at 19:55

I encountered similar problem. I dont know why but when I set parameters for example as {{user.name}} {{user.email}} etc it wouldn't work.

Solution to that was setting parameters in template as {{params.user.name}}, {{params.user.email}} etc

and then pass into SendSmtpEmail instance(_params) as anonymus object

dynamic transactionalParams = new
{
    params = new
    {
        user = new
            {
                name = "JohnDoe",
                email= "test@test.com"
            }
    }
};

then when I sent email with specified template with that parameters it worked just fine
