To customize the verification email when using HTTP courier with Mailtrap.io APIs, you need to configure the HTTP courier and provide a custom Jsonnet template for the request body. Here's how you can do it: 1. First, ensure you have configured the HTTP courier with Mailtrap.io URL and API key as you mentioned. 2. To customize the email content and structure, you need to provide a Jsonnet template for the request body. This template will define how the email data is formatted when sent to Mailtrap.io's API. 3. Here's an example of how you can configure the HTTP courier with a custom body template:

yaml courier:   delivery_strategy: http   http:     request_config:       url: <https://api.mailtrap.io/api/send>       method: POST       body: <base64://ZnVuY3Rpb24oY3R4KSB7CiAgcmVjaXBpZW50OiBjdHgucmVjaXBpZW50LAogIHN1YmplY3Q6IGN0eC50ZW1wbGF0ZV9kYXRhLnN1YmplY3QsCiAgdGV4dDogY3R4LnRlbXBsYXRlX2RhdGEuYm9keSwKICBodG1sOiBjdHgudGVtcGxhdGVfZGF0YS5ib2R5Cn0>=       headers:         Content-Type: application/json         Api-Token: your_mailtrap_api_token

The

body

field contains a base64-encoded Jsonnet template. When decoded, it looks like this:

jsonnet function(ctx) {   recipient: ctx.recipient,   subject: ctx.template_data.subject,   text: ctx.template_data.body,   html: ctx.template_data.body }

This template creates a JSON object that Mailtrap.io's API expects. You can customize this template to match the exact structure required by Mailtrap.io's API. 4. To apply this configuration, you need to update your Ory Identities configuration. You can do this using the Ory CLI or the Ory Console as described in the [Send emails using an HTTP server](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp#send-emails-using-an-http-server) documentation. Remember that the exact structure of the JSON payload might vary depending on Mailtrap.io's API requirements. You may need to adjust the Jsonnet template accordingly. Also, note that you can't use URLs to load templates in Ory Network. You must use base64-encoded templates as shown in the example above. [Custom email templates](https://www.ory.sh/docs/kratos/emails-sms/custom-email-templates#using-custom-message-templates) documentation provides more information on how to customize the content of the verification email itself.

@chilly-king-10285 My email service provider accepts the email request in this format:

{
  "from": {
    "email": "<mailto:no-reply@warrantify.me|no-reply@warrantify.me>",
    "name": "<http://Warrantify.me|Warrantify.me>"
  },
  "to": [
    {
      "email": "<Email Recipient Goes Here>"
    }
  ],
  "subject": "Email Subject Goes Here",
  "html": "<Email Body Goes Here>"
}

Please generate appropriate jsonnet format to be used it with courier as http

To generate the appropriate Jsonnet format for your email service provider's request structure, you can use the following template:

jsonnet function(ctx) {   from: {     email: "<mailto:no-reply@warrantify.me|no-reply@warrantify.me>",     name: "<http://Warrantify.me|Warrantify.me>"   },   to: [     {       email: ctx.recipient     }   ],   subject: ctx.template_data.subject,   html: ctx.template_data.body }

This Jsonnet template will generate the JSON structure that your email service provider expects. To use this with the HTTP courier in Ory Kratos, you need to encode it in base64 and include it in your configuration. Here's how you can set it up: 1. Encode the Jsonnet template to base64:

echo 'function(ctx) {   from: {     email: "<mailto:no-reply@warrantify.me|no-reply@warrantify.me>",     name: "<http://Warrantify.me|Warrantify.me>"   },   to: [     {       email: ctx.recipient     }   ],   subject: ctx.template_data.subject,   html: ctx.template_data.body }' | base64

2. Use the resulting base64 string in your Ory Kratos configuration:

yaml courier:   delivery_strategy: http   http:     request_config:       url: <https://your-email-service-provider-api-url>       method: POST       body: <base64://ZnVuY3Rpb24oY3R4KSB7CiAgZnJvbTogewogICAgZW1haWw6ICJuby1yZXBseUB3YXJyYW50aWZ5Lm1lIiwKICAgIG5hbWU6ICJXYXJyYW50aWZ5Lm1lIgogIH0sCiAgdG86IFsKICAgIHsKICAgICAgZW1haWw6IGN0eC5yZWNpcGllbnQKICAgIH0KICBdLAogIHN1YmplY3Q6IGN0eC50ZW1wbGF0ZV9kYXRhLnN1YmplY3QsCiAgaHRtbDogY3R4LnRlbXBsYXRlX2RhdGEuYm9keQp9>       headers:         Content-Type: application/json         # Add any other required headers for your email service provider

Make sure to replace

<https://your-email-service-provider-api-url>

with the actual URL of your email service provider's API. To apply this configuration, you need to update your Ory Identities configuration using either the Ory CLI or the Ory Console, as described in the [Send emails using an HTTP server](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp#send-emails-using-an-http-server) documentation. Remember that you may need to adjust the Jsonnet template if your email service provider requires additional fields or has different field names. The provided template matches the structure you specified in your question. [Custom email templates](https://www.ory.sh/docs/kratos/emails-sms/custom-email-templates#using-custom-message-templates) documentation provides more information on how to customize the content of the emails themselves, which will be used to populate the

subject

and

body

fields in this template.

I apologize for the confusion in my previous response. The error you're encountering suggests that the

body

field doesn't exist in the

ctx.template_data

object. Let's modify the Jsonnet template to use the correct fields available in the context. Here's an updated version that should work:

jsonnet
function(ctx) {
  from: {
    email: "<mailto:no-reply@warrantify.me|no-reply@warrantify.me>",
    name: "<http://Warrantify.me|Warrantify.me>"
  },
  to: [
    {
      email: ctx.recipient
    }
  ],
  subject: if "subject" in ctx.template_data then ctx.template_data.subject else "",
  html: if "body" in ctx.template_data then ctx.template_data.body.html else ""
}

This template includes some error checking to prevent the "field does not exist" error. Here's what changed: 1. We're now checking if the

subject

field exists in

ctx.template_data

before trying to access it. 2. For the HTML content, we're checking if

body

exists in

ctx.template_data

, and then accessing the

html

property within it. To use this updated template: 1. Encode it to base64:

echo 'function(ctx) {
  from: {
    email: "<mailto:no-reply@warrantify.me|no-reply@warrantify.me>",
    name: "<http://Warrantify.me|Warrantify.me>"
  },
  to: [
    {
      email: ctx.recipient
    }
  ],
  subject: if "subject" in ctx.template_data then ctx.template_data.subject else "",
  html: if "body" in ctx.template_data then ctx.template_data.body.html else ""
}' | base64

2. Use the resulting base64 string in your Ory Kratos configuration:

yaml
courier:
  delivery_strategy: http
  http:
    request_config:
      url: <https://your-email-service-provider-api-url>
      method: POST
      body: <base64://ZnVuY3Rpb24oY3R4KSB7CiAgZnJvbTogewogICAgZW1haWw6ICJuby1yZXBseUB3YXJyYW50aWZ5Lm1lIiwKICAgIG5hbWU6ICJXYXJyYW50aWZ5Lm1lIgogIH0sCiAgdG86IFsKICAgIHsKICAgICAgZW1haWw6IGN0eC5yZWNpcGllbnQKICAgIH0KICBdLAogIHN1YmplY3Q6IGlmICJzdWJqZWN0IiBpbiBjdHgudGVtcGxhdGVfZGF0YSB0aGVuIGN0eC50ZW1wbGF0ZV9kYXRhLnN1YmplY3QgZWxzZSAiIiwKICBodG1sOiBpZiAiYm9keSIgaW4gY3R4LnRlbXBsYXRlX2RhdGEgdGhlbiBjdHgudGVtcGxhdGVfZGF0YS5ib2R5Lmh0bWwgZWxzZSAiIgp9>
      headers:
        Content-Type: application/json
        # Add any other required headers for your email service provider

This updated template should resolve the "field does not exist: body" error. If you're still encountering issues, you might want to check the exact structure of the

ctx

object that Ory Kratos is passing to the template. You can do this by adding some debug output to your template, like this:

jsonnet
function(ctx) {
  debug: std.trace(std.toString(ctx), "Context:"),
  // ... rest of your template
}

This will print the entire context object to the logs, which can help you understand what fields are available and how to access them correctly.

@chilly-king-10285 How do I provide "from" value in http courier configuration

To provide the "from" value in the HTTP courier configuration for Ory Kratos, you need to include it in the Jsonnet template that defines the structure of your email request. Here's how you can do it: 1. First, you need to modify your Jsonnet template to include the "from" field. You can set it directly in the template or use a value from the context if available. Here's an example:

jsonnet function(ctx) {   from: {     email: "<mailto:no-reply@example.com|no-reply@example.com>",     name: "Your Company Name"   },   to: [     {       email: ctx.recipient     }   ],   subject: if "subject" in ctx.template_data then ctx.template_data.subject else "",   html: if "body" in ctx.template_data then ctx.template_data.body.html else "" }

2. After creating your Jsonnet template, you need to encode it to base64 and include it in your Ory Kratos configuration. Here's an example of how your configuration might look:

yaml courier:   delivery_strategy: http   http:     request_config:       url: <https://your-email-service-provider-api-url>       method: POST       body: <base64://ZnVuY3Rpb24oY3R4KSB7CiAgZnJvbTogewogICAgZW1haWw6ICJuby1yZXBseUBleGFtcGxlLmNvbSIsCiAgICBuYW1lOiAiWW91ciBDb21wYW55IE5hbWUiCiAgfSwKICB0bzogWwogICAgewogICAgICBlbWFpbDogY3R4LnJlY2lwaWVudAogICAgfQogIF0sCiAgc3ViamVjdDogaWYgInN1YmplY3QiIGluIGN0eC50ZW1wbGF0ZV9kYXRhIHRoZW4gY3R4LnRlbXBsYXRlX2RhdGEuc3ViamVjdCBlbHNlICIiLAogIGh0bWw6IGlmICJib2R5IiBpbiBjdHgudGVtcGxhdGVfZGF0YSB0aGVuIGN0eC50ZW1wbGF0ZV9kYXRhLmJvZHkuaHRtbCBlbHNlICIiCn0>=       headers:         Content-Type: application/json

The "from" value is now included directly in the Jsonnet template, which is then base64 encoded and used in the configuration. To apply this configuration, you need to update your Ory Identities configuration using either the Ory CLI or the Ory Console, as described in the [Send emails using an HTTP server](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp#send-emails-using-an-http-server) documentation.
