Refresh datasource when data comes from post api

[MCPowerBI]

I have writen a small m script that gets its data from a post call to an api:

let
   url="https://this.isaurl.com",
   body =  "
         {
            ""Id"":""Id123456""
            ""Authenticator"": ""AUTH_KEY"" 
         }
   ",
   Data=Web.Contents(url,
   [RelativePath="My/Relative/Path",
   Content=Text.ToBinary(body),
   Headers=[#"Content-Type"="application/json"]
   ]),
   DataRecord = Json.Document(Data),
in
   DataRecord

In the powerbi desktop app there is no problem refreshing the query.

When the report is published and I try to refresh on the powerbi service.

The given error is:

The credentials provided for the Web source are invalid.

I have found these blog posts and followed them, but with no luck

Hi, @MCPowerBI ;

Take a look at this document.

https://docs.microsoft.com/en-us/power-bi/connect-data/service-admin-troubleshooting-power-bi-person...

Error: The credentials provided for the dataset are invalid. Please update the credentials through a refresh or in the Data Source Settings dialog to continue.

Solution: If you get a credentials message, it could mean:

• The usernames and passwords that you used to sign in to data sources aren't up to date. In Power BI, go to refresh settings for the dataset. In Manage Data Sources, select Edit credentials to update the credentials for the data source.

• Mashups between a cloud source and an on-premises source, in a single query, fail to refresh in the gateway (personal mode) if one of the sources is using OAuth for authentication. An example of this issue is a mashup between CRM Online and a local SQL Server instance. The mashup fails because CRM Online requires OAuth.

  This error is a known issue, and it's being looked at. To work around the problem, have a separate query for the cloud source and the on-premises source. Then, use a merge or append query to combine them.

• Use the same credentials and privacy level like in Power BI Desktop and Service.

You need to confirm that you are using the same permissions (same credentials type and same privacy level).  Then, you also need to confirm that the gateway is actually reaching the data - is it firewalled off or other security blocking it?
