Get Data from Web API using HTTP Header



I'm querying website (name anonymized) by sending an HTTP message with an additional header which contains the API key.


I'm using the Power BI formula


Web.Contents("", [Headers=[#"API-Key"="asdf123"], Query = [#"v"="1.1", #"from"="0"]]) for this.


In Power BI Desktop I receive all my data without any complains. But when I upload the data model to and try to refresh the dataset there, Power BI complains that my login information is wrong.

Re: Get Data from Web API using HTTP Header



Indeed, i'm having the same issue, i don't know why.


Please, microsoft power bi team, could you fix this issue? Power Bi service make sense if we can schedule the refresh of this kind of webservice.


@BI did you find any solution for this?

Re: Get Data from Web API using HTTP Header

Hello, I'm having a different issue, but related I think. I'm using the same code as OP but I get the error "The '(header)' header is only supported when connecting anonymously". Removing the header containing the token returns another error that the GET method is not supported. I have no idea what I'm doing wrong, very new to API's. I can query a new token from the API in question through PBI, as well use the mock server they have. But can't connect using my own token
