powershell command not found exception -Method

Question

While using the following in powershell its copied from a website to process online payments thro an application. I change the access token and unique key when writing this.

$authHeader = @{ Authorization = 'Bearer  {0}' -f "{{ACCESS_TOKEN}}" }
$body = '{
   "idempotency_key": "{{UNIQUE-KEY}}",
   "autocomplete": true,
   "amount_money": {
     "amount": 100,
     "currency": "USD"
   },
   "source_id": "cnon:card-nonce-ok"
   }
}'

Invoke-RestMethod -Uri https://connect.squareupsandbox.com/v2/payments |
  -Method Post |
  -ContentType "application/json" |
  -Headers $authHeader |
  -Body $body

i get the following exception

-Method : The term '-Method' is not recognized as the name of a cmdlet, function, script file, or operable program.
 Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
  At line:14 char:4   
     +    -Method Post |                                      
 +    ~~~~~~~

 + FullyQualifiedErrorId : CommandNotFoundException

or if i remove these | and use space instead like comment said,

$authHeader = @{ Authorization = 'Bearer  {0}' -f "{{ACCESS_TOKEN}}" }
$body = '{
   "idempotency_key": "{{UNIQUE-KEY}}",
   "autocomplete": true,
   "amount_money": {
     "amount": 100,
     "currency": "USD"
   },
   "source_id": "cnon:card-nonce-ok"
   }
}'

Invoke-RestMethod -Uri https://connect.squareupsandbox.com/v2/payments 
  -Method Post 
  -ContentType "application/json" 
  -Headers $authHeader 
  -Body $body

i get the following exception and as shown the old -Method exception is still there.

Do not use the pipe character | to separate your parameters, they should be space separated — arco444

While the pipe | can be used to break a line into multiple lines, that statement apply only apply for a series of command using the pipeline in the first place.

Parameters tied to a command cannot be separated by the pipeline like that.

You have 3 options.

Put all your parameters on the same line, space separated, like this:

Invoke-RestMethod -Uri https://connect.squareupsandbox.com/v2/payments -Method Post -ContentType "application/json" -Headers $authHeader -Body $body

Use Splatting and define your parameters into a hashtable, then apply them to the command using @ to specify you are passing a list of parameters and these values and not simply a single hashtable parameter.

$params = @{
    ContentType = "application/json"
    Method = 'Post'
    Body = $body
    Headers = $authHeader
    Uri = 'https://connect.squareupsandbox.com/v2/payments'
}
Invoke-RestMethod @params

Use the backtick ` character.

Invoke-RestMethod -Uri https://connect.squareupsandbox.com/v2/payments `
    -Method Post `
    -ContentType "application/json" `
    -Headers $authHeader `
    -Body $body
