Regarding Sending Authorization in HTTP Request Headers

(0) ShareShare

Posted on by YD-22100952-0 29

Hi all,

I am trying to send an HTTP request from Power Automate (Flow) and I need to include an Authorization header. I have a variable called "MyToken" that stores my token.

I tried the following in the Headers field:

{
"Date": @{variables('MyDate')},
"Content-Type": "application/json",
"Authorization": @{variables('MyToken')}
}
 

However, this header now causes an error: the Authorization part is being sent empty to the server. Note that MyToken is not empty — using the same value in Postman works successfully.

Note 1: I cannot use a custom connector because the token for the connection changes constantly.

Note 2: This flow was working on November 5th. It seems that after a recent update, the Authorization header can no longer be sent. However, the server still expects the Authorization to be in the header.

Thanks in advance!

    Hi 
     
    Is variables('MyToken') really a plain string and does it contain Bearer <Token>? 
     
    Is the Authentication property set to None?

    Hello,

    The Authentication field has “none” selected.

    The MyToken variable is not a Bearer token; it’s a key specifically expected by the server.

    When I send the request using the same header and body in Postman, it works successfully. However, when I send the request via Automate, the authorization field is sent as empty.
