Sendgrid-nodejs: Dynamic Template Data is not showing!

Created on 14 Aug 2018 · 15Comments · Source: sendgrid/sendgrid-nodejs

template html code:
<div style="text-align: center;"><span style="font-size:28px;"><strong><p>Code: {{voucherCode}}</p></strong></span></div>

Nodejs Code:

    sgMail.setApiKey(process.env.SENDGRID_API_KEY);
    //sgMail.setSubstitutionWrappers('{{', '}}'); // Configure the substitution tag wrappers globally
    const msg = {
        to: '[email protected]',
        from: '[email protected]',
        templateId: 'd-787c96877a394be5b95c91750622fed1',
        dynamicTemplateData : {
            voucherCode: "Some One"
        },
    };
    sgMail.send(msg)

When I received the email, the voucherCode is empty!

It looks like the dynamic_template_data _must_ be inside a personalizations array in order for it to work.

This works for me:

from: '[email protected]',
subject: 'Thanks for your recent review',
templateId: 'template_id',
personalizations: [
            {
              to: {
                name: 'Some One',
                email: '[email protected]'
              },
              dynamic_template_data: {
                review: {
                  url: 'https://www.google.com'
                }
              }
            }
          ]

I'm having the same issues. I've spent already like 4 hours. What's going on?
I'm seeing some issues with other languages too

@kayson123 I did a last change and it was updating to the last release https://github.com/sendgrid/sendgrid-nodejs/issues/703#issuecomment-411058053

Now is working for me. Try doing that.

juliankmazo on 15 Aug 2018

Hello @kayson123,

Have you upgraded the SDK to v6.3.1?

Also, you may try {{ voucherCode }} vs {{voucherCode}}.

Thanks!

With Best Regards,

Elmer

Above poster is correct. There is a bug either in the library code or typescript definitions.

export interface PersonalizationData {
  to: EmailData | EmailData[],
  cc?: EmailData | EmailData[],
  bcc?: EmailData | EmailData[],
  subject?: string;
  headers?: { [key: string]: string };
  substitutions?: { [key: string]: string };
  dynamicTemplateData?: { [key: string]: string; };
  customArgs?: { [key: string]: string };
  sendAt?: number;
}

This would suggest that you can pass dynamicTemplateData as a value in PersonalizationData, but it has to actually be snake case, dynamic_template_data.

Hi @raine,

I believe this PR addresses that issue. I hope that helps!

With a fresh install of sendgrid 6.4.0, this issue is still present. The dynamic template data, is only working if passed with dynamic_template_data, but types suggests dynamicTempalteData.

I'm facing the same issue. Are the typescript definitions for the library incorrect? Can someone please respond.

I spent 2 hours trying to debug this issue only to realize that the issue occurs on a BCC'ed email.

Is there any workaround to this issue? I'm facing the same problem.

CShigaki on 11 Feb 2020

@CShigaki Could you provide sample code and template that's not working? And what library version are you using?

childish-sambino on 11 Feb 2020

@childish-sambino I'm actually using a PHP library and the problem only occurs as @coolnalu said. When setting a BCC through the sendgrid interface (https://app.sendgrid.com/) instead of setting it with code, the email sent to the BCC does not receive (or apply, I don't know yet) the dynamic template data. I have no idea why this happens but I solved it by setting the BCC via code.

CShigaki on 12 Feb 2020

Yup, I'm seeing the same issue. The To and Bcc get the email, but the dynamic template is not populated in the Bcc when using the global Bcc account setting. Unfortunately, that's not something that we can resolve in this helper lib so best to create a support ticket to request that this bug be fixed in the backend.

The solution that worked for me is placing the dynamic_template_data inside the personalization object in the exact way seen below:

    "personalizations": [
        {
              "dynamic_template_data": {
            "fullname": "full Name",
            "useremail": ":[email protected]",
            "userphone": "56456",
            "usermsg": "tex fdsfgasdf t"
    },
            "to": [
                {
                    "email": "[email protected]"
                }
            ],
            "cc": [
                {
                    "email": "[email protected]"
                }
            ]
        }
]
