Calling the Indeed API in PowerBI using Power Query M

* I will preface this post by saying I am very much a novice when it comes to Power query M*

Hello,

I have been racking my head trying to get this work for the better part of a week. I am trying to generate an access token in PowerBI from Indeed and calling this specific API, which uses O-auth 2.

I have already successfully generated an access token and called the API mentioned above in POSTMAN. I have pasted it below (in HTTP format), but omitted the "sensitive" information:

Generating the Access Token:

POST /oauth/v2/tokens HTTP/1.1
Host: apis.indeed.com
Content-Type: application/x-www-form-urlencoded
Accept: application/json
Cookie: SURF=HibVklQ4yZY24rS0AuOWqlIwnDJqRHG1; CTK=1g2ru0havptte801
Content-Length: 205

client_id="client_ID"&client_secret="client_secret"&grant_type=client_credentials&scope=employer_access

Calling the API I specified:

GET /ads/v1/campaigns/eb2ce79c18b45740/stats?startDate=2022-05-01&endDate=2022-05-09&merge=FALSE HTTP/1.1
Host: apis.indeed.com
Content-Type: application/x-www-form-urlencoded
Accept: application/json
Cookie: SURF=HibVklQ4yZY24rS0AuOWqlIwnDJqRHG1; CTK=1g2ru0havptte801
Content-Length: 279

client_id="client_id"&client_secret="client_secret&grant_type=client_credentials&scope=employer_access%20employer.advertising.campaign&employer=912e79a21b66f29151f06b0dba3bb07d

As I said, both of these are working fine in POSTMAN. Transferring them into PowerBI is where I am having an issue. Is there any way to easily translate HTTP to M?

I have been using this sample Pseudo code below: 

let
 AccessToken = Json.Document(Web.Contents("https://apis.indeed.com/oauth/v2/tokens",
 [
 Headers=[Accept="application/json", ContentType="application/x-www-form-urlencoded"],
 Content=Text.ToBinary(
 "grant_type=client_credentials&
 client_id=CLIENT_ID&
 client_secret=CLIENT_SECRET&
 scope=ACCESS_SCOPE"
 )
 ]))[access_token],
 JsonData = Json.Document(Web.Contents("https://apis.indeed.com/ads/v1/campaigns/{campaignId}/stats",
[Headers=[Accept="application/json",#"Authorization"="Bearer " & AccessToken]])),
 // Use the data
 #"Converted to Table" = Table.FromList(JsonData, Splitter.SplitByNothing(), null, null, ExtraValues.Error)

When I add in my values to this code, I am receiving the following error:

I am honestly stumped and would love some advice. The code above could have some tiny mistakes or be completely wrong. Any help is appreciated! Thank you!
