Use Templates in Email API
Create, update, delete, and fetch email templates. Use an email template in email APIs.
You can use templates in email APIs to send standard/uniform email messages to customers. By default, the email APIs must be sent only with an approved template.
In order to get a new email template approved, contact your Kaleyra account manager or reach out to the support team, see support. A template is approved based on its relevance to the brand details of the product.
You cannot send an email without a template by default. To enable the email service without a template, contact your Kaleyra account manager or reach out to the support team, see support.
In the email templates, you can specify the values for the parameters, 'from', 'subject', html_body, text_body, and template_name. The parameter values that you provide in the email API call take precedence(override) over the corresponding parameters in the email template.
While using a template in the email API, you must provide the template_id. Make sure to note down the template_id to be able to use in an email API.
Note:
- You can use a textly URL in an email template 'html_body' parameter.
- Both 'static' and 'dynamic' textly URLs are supported.

Use a template in an email API
You can use a template while sending an email API request. To use a template in the email API request, you must specify the template_id.

<https://URL/v1/><SID>/email
For example:
<https://api.kaleyra.io/v1/><SID>/email
Subject in email API overrides the subject in the template
-
When the subject in the template is empty, and the email API has a subject, then the email is delivered with the subject passed via the email API.
-
When the template has a subject and the email API does not have a subject, then the email is sent with the subject added from the template.
-
When the template has a subject and the email also has a subject, then the subject in email API takes precedence and the email is delivered with the subject from the email API.
-
When both the template and the email API do not have a subject, the email cannot be delivered as the subject in API is mandatory for the email to be delivered and you must pass a subject in the email API.
{
"from": "[email protected]",
"from_name": "No Reply Email from Kaleyra",
