Hash for gmail one click unsubscribe headers

[k040711]

Hi everyone,

I'm trying to set up the additional headers google is asking for as of 2024's new guidelines for one click unsubscribe headers but having trouble understanding how to implement this in Postal's email API send

google requires 2 additional header lines:
(from google's documentation)
Header 1:
List-Unsubscribe-Post: List-Unsubscribe=One-Click

Header 2:
List-Unsubscribe: https://myautoresponder.com/unsubscribe/example

In postal's documentation additional headers are to be included as hashed <- this is the part i'm having trouble with

Can someone post an example of how to include this with an api request?

here's an example of a typical api send request i send:

{
"from": "Me [email protected]",
"to": [
"[email protected]"
],
"subject": "test email",
"html_body": "

testing lone click unsubscribe

"
}

when I tried to add an additional "headers" : to the json it gives me an error saying the value of headers is a string and its not hashed.

thank you.

which programming language are you using? Are you using one of the libraries? https://docs.postalserver.io/developer/client-libraries

yeah i figured it out,

all its asking for is a json object with the headers, like this:

"headers" : {
"list-unsubscribe-post":"list-unsubscribe-post"
}
etc...

works great now.
