Workflows: Dynamically provide custom email template

Hi there! I want to build a workflow where I digest a few events and then send out an email with a list of those. I use Brevo (Sendinblue) to send these emails. I would like to either create the email templates 1. using Brevo (https://developers.brevo.com/docs/send-a-transactional-email#creating-your-api-request-using-brevo-api-clients) 2. or generate them by myself by feeding react-email/vue-email (which renders to html) with the events data and then send this email. Is there currently a way of doing this?

TLDR: Is there a way to execute an integration (sending an email) and customizing the parameters of this API call?

Hey @Fabian B. To customize the parameters of an API call when executing an integration such as sending an email with Novu, you can use the overrides field in your trigger call. This allows you to specify the integrationIdentifier to select the email provider, such as Brevo (Sendinblue), and pass custom parameters like templateId and personalization if you're using a specific template from your email provider. For example, using a MailerSend template with Novu would look like this:

import { Novu } from '@novu/node';
const novu = new Novu('<NOVU_API_KEY>');

await novu.trigger("workflowIdentifier", {
  to: "subscriberId",
  payload: {},
  overrides: {
    email: {
      customData: {
        // mailersend template templateId
        templateId: 'mailersend-template-id',
        // mailersend template variables
        personalization: [{
          email: '[email protected]',
          data: {
            items: {
              price: '',
              product: '',
              quantity: '',
            },
            order: {
              date: '',
              order_number: '',
              billing_address: '',
              customer_message: '',
            },
            store: {
              name: '',
            },
            invoice: {
              total: '',
              subtotal: '',
              pay_method: '',
            },
            customer: {
              name: '',
              email: '',
              phone: '',
            },
          },
        }],
      },
    }
  },
  // actorId is subscriberId of actor
  actor: "actorId",
  tenant: "tenantIdentifier"
});

import { Novu } from '@novu/node';
const novu = new Novu('<NOVU_API_KEY>');

await novu.trigger("workflowIdentifier", {
  to: "subscriberId",
  payload: {},
  overrides: {
    email: {
      customData: {
        // mailersend template templateId
        templateId: 'mailersend-template-id',
        // mailersend template variables
        personalization: [{
          email: '[email protected]',
          data: {
            items: {
              price: '',
              product: '',
              quantity: '',
            },
            order: {
              date: '',
              order_number: '',
              billing_address: '',
              customer_message: '',
            },
            store: {
              name: '',
            },
            invoice: {
              total: '',
              subtotal: '',
              pay_method: '',
            },
            customer: {
              name: '',
              email: '',
              phone: '',
            },
          },
        }],
      },
    }
  },
  // actorId is subscriberId of actor
  actor: "actorId",
  tenant: "tenantIdentifier"
});

Thanks @Emil for the quick response! I will check if that will work 🙂

empe•10mo ago

Hey @Fabian B.! Did you manage to get your desired outcome?

Fabian B.OP•10mo ago

Thanks for getting back @Emil, unfortunately, I weren't able to get it to run. It still sends the html generated by Novu to Brevo. It does not use the template, even though I set it in the overrides request body. Besides that, I do not see it working with Digests nevertheless, because when you think of it, you're overriding a single event with the customData. In my case, Brevo should recieve an array of all data and loop through this array to generate the template. But imagine you have 10 events before the digest runs and sends the email, every event override would erase the event data before. So at the end, you would still only have one array element. Since I cannot add the step.events array to the customData override.

Fabian B.OP•10mo ago

This is the API request format Brevo expects. This works fine when sending directly to Brevo. For this to work, I would have to replace the "jobs" array in the screenshot with the step.events array from novu at the moment where the digest is running, not at the moment I send out the event.

@Fabian B., you just advanced to level 2!

Fabian B.OP•10mo ago

Just discovered that there is the "Email Webhook" integration, which I can use to send the event data to my API. I have to test it a bit but seems that solves my issue. Since I can then just call the brevo api myself

empe•10mo ago

@Fabian B. Once you done testing it, could you please share the results and your insights?

Fabian B.OP•10mo ago

Sure! So I have setuped a simple workflow like this. In the Webhook Settings, I pointed the URL to my server. Novu then sends me a webhook request when it would normally send out an email. The payload of this HTTP request contains the step.events array, which I can then use to send out the actual email with Brevo. This solution now works fine on my side, and I can still benefit from everything novu has to offer, especially the digest engine.

That's lovely! Where do you think we could add this to in our documentation? cc: @Pawan Jain
