Sendgrid Substitutions Tags - node.js

Question

I want to send a notification email in my application and I am trying to use sendgrid. My application is writtin in CoffeeScript.
enter code here
from_address = 'noreply#example.co'
subject = 'This Is The Subject'
html_body = '<table style="font-family: verdana, tahoma, sans-serif; color: #000;">
<tr> <td>
<h2>Hello,</h2> <p>Hello!!</p>
<p>%%name%% %%surname%% send you a message</p>
</table>'
sendgrid = require('sendgrid')(api_key)
Email = sendgrid.Email
email = new Email(
to: to_address
from: from_address
subject: subject
text: text_body
html: html_body)
recipients = [
'example1#example.com'
'example2#example.com'
]
i = 0
while i < recipients.length
email.addTo recipients[i]
i++
substitutions = {
"%%name%%": [
"name1",
"name2"
],
"%%surname%%": [
"surname1",
"surname2"
]
}
for tag in substitutions
email.addSubstitution(tag, substitutions[tag])
email.setFilters({
"templates": {
"settings": {
"enable": "1",
"template_id": "XXXXXX-XXX-XXXX-XXXX-XXXXXXXXXX"
}
}
})
sendgrid.send email, (err, json) ->
if err
return console.log(err)
console.log json
return
When I execute the code send my the email to the emails address. But the message is:
Hello!!
%%name%% %%surname%% send you a message.
The substitution doesn't work. I try changing %% for %,- and #. But any ot those seems to work. Also I try using setSections.
Update
This is the sendgrid object i am sending.
{ to: [ 'example1#example.com', 'example2#example.com' ],
from: 'noreply#example.co',
smtpapi:
{ version: '1.2.0',
header:
{ to: [],
sub: {},
unique_args: {},
category: [Object],
section: {},
filters: [Object],
send_at: '',
send_each_at: [],
asm_group_id: {},
ip_pool: '' } },
subject: 'This Is The Subject',
text: 'Hello!\n\nThis is a test message from SendGrid. We have sent this to you because you requested a test message be sent from your account.\n\n This is a link to google.com: http://www.google.com\n This is a link to apple.com: http://www.apple.com\n This is a link to sendgrid.com: http://www.sendgrid.com\n\n Thank you for reading this test message.\n\nLove,\nYour friends at SendGrid',
html: '<table style="font-family: verdana, tahoma, sans-serif; color: #000;"> <tr> <td> <h2>Hello,</h2> <p>Hello!!</p> <p>%%name%% %%surname%% send you a message</p> </table>',
bcc: [],
cc: [],
replyto: '',
date: '',
headers: {},
toname: undefined,
fromname: undefined,
files: [] }
What am I doing wrong?
Thank you in advance.

Answer 1

I answer my own question because already found the problem.
The problem was not related with Sendgrid but with coffeeScript. In one of my statement I use this:
for tag in substitutions
email.addSubstitution(tag, substitutions[tag])
I try here to add to the email object the substitutions tag. But the debuging my code I found that the loop was not iterating over the substitution variable. So any tag was added to the email object.
I've changed the previous code for this one:
Object.keys(substitutions).forEach((tag)->
email.addSubstitution(tag, sub[tag])
return
And with this change the substitutions tags was added to the email object.
