Configured for but not sending in JSON

I have your notification plugin triggering and then sending to another application using Json. I will post snapshots of the configuration. the support people at the other application are telling me that it’s only coming in as text

Payload
{“cid”:”25640″,”permalink”:”https:\/\/halfgenius.wpengine.com\/referral-agent-library\/”,”slug”:”referral-agent-library”,”title”:”AGENT \u2013 Referral Agent Library”,”excerpt”:””,”modified”:”August 26, 2018 6:01 pm”,”source_type”:”page”,”source”:”wp_putp”}

See request detail here

Here is what I copied from the receiving app

THIS WAS IN THE HEADER
———————-
{
‘content-type’: [
‘application\/x-www-form-urlencoded’
],
‘content-length’: [
‘391’
],
‘connection’: [
‘close’
],
‘referer’: [
‘https:\/\/putp.flexie.io\/listener\/f719b3e223c19a79954a540742605fb2\/5027ca5a586ae33703becf03d4beb5e9’
],
‘accept-encoding’: [
‘deflate, gzip’
],
‘accept’: [
‘*\/*’
],
‘user-agent’: [
‘WordPress\/4.9.8; https:\/\/halfgenius.wpengine.com’
],
‘host’: [
‘putp.flexie.io’
]
}

THIS WAS IN THE PAYLOAD
———————-
{
‘{\’cid\’:\’28882\’,\’permalink\’:\’https:\\\/\\\/halfgenius_wpengine_com\\\/?post_type’: ‘topics’,
‘#038;p’: ‘28882\’,\’slug\’:\’future-what-if-i-dont-want-to-fix-everything-before-selling-do-i-have-to-fix-everything\’,\’title\’:\’FUTURE: What if I don\\u2019t want to fix everything before selling? Do I have to fix everything?\’,\’excerpt\’:\’\’,\’modified\’:\’August 25, 2018 9:07 am\’,\’source_type\’:\’topics\’,\’source\’:\’wp_putp\’}’
}

I added the header in my first example.

They do receive it it’s just received in a format that is not Json

Here is the whole configured notification

I will send to https://bracketspace.com/extras/webhook/sabi.php
