Passing json parameters to REST API data source

[CHP]

I have a data source that is a REST API.  To query this API I pass in some headers for credentials, and some json inputs.  The curl for it looks like so :

curl -X POST -d '{"parameter_name":"parameter_value"}' -H 'Content-Type: application/json' -H 'Cookie: my_credential_key=my_credential_value' https://my.endpoing.com/api/endpoint/

the json passed in can be more complicated too (it can contain multiple parameters, one of the parameter values may be a URL, etc)

I'm not sure how to use the Web data source or the Blank Query to get data back from this API.  In the Web data source can figure out how to pass in the cookie header, and the content-type header as well, but I'm not sure how to pass in the -d {"parameter_name":"parameter_value"}

Any help would be appreciated 🙂

Hi @CHP,

As far as I know, in Power Bi, we can pass query parameters as described in this thread. The parameter is a single value parameter. It is not available to pass json formatted parameters like {"parameter_name":"parameter_value"}. Rather than recognizing each specific value from  {"parameter_name":"parameter_value"} one by one, it might consider this as a whole entity.
