@AnilYadav-2387 Thanks for reaching out. To authenticate a function using a client certificate in Azure Logic Apps, you can use the "Client Certificate" option in the HTTP action. You need to specify the following property values:

• Authentication: type (Required)
  • Value: Client Certificate or ClientCertificate
• Pfx: pfx (Required)
  • Value: base64-encoded content from a Personal Information Exchange (PFX) file
• Password: password (Optional)
  • Value: password for accessing the PFX file

Here is an example HTTP action definition that specifies the authentication type as ClientCertificate:

"HTTP": { "type": "Http", "inputs": { "method": "GET", "uri": "@parameters('endpointUrlParam')", "authentication": { "type": "ClientCertificate", "pfx": "@parameters('pfxParam')", "password": "@parameters('passwordParam')" } }, "runAfter": {}
}

For more information, you can refer to this document and make sure you go through some of the errors documented here. For base64 encode please refer to base64 function.
