API POST using Graphql

Silvio.Gerstenberger — Tue, 23 Jun 2020 07:57:00 GMT

Are there any possibilities or experiences in using Graphql in blue prism?

The Graphl ql API says, that there is no query provided but it is shown in the post body in bp. In postman the query is working fine.

Hope you can help me or have a helping hint for me.

Hi Silvio,
I have started working on graph QL API recently, don't know whether you need it or not now.
The exception "there is no query provided" is due to passing the multiline json data in the body or request payload. To pass the multiline data, we need to use \n instead of writing text in a newline.
For example:

{

"query":"{

rockets {

country

description

diameter {

feet

meters

}

}

This needs to be written in Blue Prism in expression editor as follows:

"{""query"":""{\n rockets{\n country\n description\n diameter{\n feet\n meters\n}\n}\n}""}"

A basic implementation of the API POST in graph QL is available in the below link. Please find it as a reference.

As @sravangoud implied, GraphQL is a bit more formal with regards to input than your average RESTful service. Here's an example of a simple public service I created a quick Web API service definition for as a test:

Note, the query portion of the body must be created essentially as a string with embedded newlines. You can test against this same public service and view it's schema here: https://countries.trevorblades.com/
