Hello,  
I am trying to use a value from a Custom Credential Type in a Webhook Notification header, but nothing I am trying works.

Scenario:  
Custom Credential Type = Webhook Keys with the following definition:  
“inputs”: {  
“fields”: [  
{  
“id”: “App\_API\_username”,  
“type”: “string”,  
“label”: “API\_Username”  
},  
{  
“id”: “App\_API\_Key”,  
“type”: “string”,  
“label”: “API\_Key”,  
“secret”: true  
}  
]  
},  
“injectors”: {  
“extra\_vars”: {  
“App\_API\_Key”: “{{ App\_API\_Key }}”,  
“App\_API\_USERNAME”: “{{ App\_API\_username }}”  
}  
}

I have created the following Credential using that custom type:  
“name”: “Dev API Key”  
“inputs”: {  
“App\_API\_Key”: “$encrypted$”,  
“App\_API\_username”: “”  
},

What I am having a hard time figuring out is how to get the App\_API\_Key value for that credential into a Webhook Notification header:

{  
“content-type”: “application/json”,  
“key”: “ **{this is where I need the value from the credential}** ”  
}

Any ideas on how I can accomplish this?

JT

If I’m understanding what you’ve said correctly. It would be `App_API_Key`.

Assuming in AWX you have your Job Template and you’ve created a Credential from the custom Credential Type and associated it with the Job Template, in your playbook:

```yaml
---
- hosts: localhost
  tasks:
    - ansible.builtin.uri:
      url: https://some-webhook-service.example.tld
      headers:
        key: "{{ App_API_Key }}"

```

I need it in a Webhook Notification header, not in a playbook.

The closest I’ve found in 4 days of google/documentation searching is:  
{{ ‘Dev API Key’ | **App\_API\_Key** (‘App\_API\_Key’) }}

But the filter **App\_API\_Key** is not built-in, and not recognized. I don’t know what filter to use for a customer credential type.

The only thing left I can think to try is use the Custom Credential type name as the filter, but I suspect I would need to remove the space in it.

OK, you’re configuring a Notification Template with the Webhook type. That wasn’t clear to me in your initial post.

I don’t know of any way to access a Credential within a Notification Template. I don’t think it’s possible. The AWX Community documentation shows an example with an `Authentication` header having the value directly.

Yep, I’ve been all over the docs. Here is another suggestion Google came up with:

```auto
{
      "Authorization": "Basic {{ '{{' }} MyWebhookAuth.username {{ '}}' }}:{{ '{{' }} MyWebhookAuth.password {{ '}}' }} | b64encode }}"
}

```

But so far it’s not working using my values.
