How to send mail using template from Design Library

[scottbarrow]

Issue Summary

I am able to send emails via the V3 API using a template_id, and dynamic_template_data, however when I use a template_id from the Design Library, the API responds with "Cannot use dynamic template data with a legacy template ID".
Is it possible to send using a designs template?

Thanks

Steps to Reproduce

1. Send email using a template_id from the Design Library

Technical details:

• sendgrid-ruby version: 6.0.0
• ruby version: 2.6.5

I actually get a 202 response, but it doesn't actually read the "to" email in the personalizations array. So it never gets sent. It shows up in our Sendgrid activity page as undeliverable without a proper email address, although clearly I sent it in the api request.

I even used their v3 api docs curl/in-browser-terminal test, ON THEIR DOCS page, and put in my info (api key, email address, etc), and it still didn't go through. Something's definitely up with their system.

I'm having the same issue as @courtsimas. I have followed their examples and tried different things but it's not working. The add_to method it's not working.

I actually got it to work. It was the following, in combination with a good API Key that had full access.

    mail = SendGrid::Mail.new
    mail.template_id = 'd-something123'
    mail.asm = SendGrid::ASM.new(group_id: 01234)
    mail.from = Email.new(email: 'ex@example.com', name: 'the name')
    mail.subject = 'subject'
    personalization = Personalization.new
    personalization.add_to(Email.new(email: 'someemail@example.com, name: 'the name'))
    personalization.add_dynamic_template_data('first_name' => 'first')
    personalization.add_dynamic_template_data('last_name' => 'last')
    personalization.add_dynamic_template_data('sender_name' => 'my company')
    personalization.add_dynamic_template_data('sender_address' => 'great street')
    personalization.add_dynamic_template_data('sender_city' => 'some city')
    personalization.add_dynamic_template_data('sender_state' => 'the state')
    personalization.add_dynamic_template_data('sender_zip' => '12345')
    mail.add_personalization(personalization)
    ....
    #<proceed to send email>

@scottbarrow Best I can tell, it's not possible. The design needs to be added to a dynamic template in order to accomplish sending with dynamic template data.
