An example on using the Github GraphQL API with Python 3

# An example to get the remaining rate limit using the Github GraphQL API.

import requests

def run_query(query): # A simple function to use requests.post to make the API call. Note the json= section.
    request = requests.post('https://api.github.com/graphql', json={'query': query}, headers=headers)
    if request.status_code == 200:
        return request.json()
    else:
        raise Exception("Query failed to run by returning code of {}. {}".format(request.status_code, query))

        
# The GraphQL query (with a few aditional bits included) itself defined as a multi-line string.       
query = """
{
  viewer {
    login
  }
  rateLimit {
    limit
    cost
    remaining
    resetAt
  }
}
"""

result = run_query(query) # Execute the query
remaining_rate_limit = result["data"]["rateLimit"]["remaining"] # Drill down the dictionary
print("Remaining rate limit - {}".format(remaining_rate_limit))

Very helpful, thank you!

If you're using a Personal Access Token (PAT), you need to put the word "token" or "bearer" before the actual token:
headers = {"Authorization": "token XYZ123TOKENTOKENTOKEN"}

Very helpful demonstration 👏

Great demo! I only had to tweak the url which, for GitHub Enterprise, seems to have a slightly different scheme: e.g. https://github.mycompany.com/api/graphql

Very helpful! Thank you!

Thanks! :D

If you get a 401 code, do what @YakDriver says

Thanks!

Thanks!

we can also do a get request right with python request's module
to consume the api and use it to display the data right something like this.

r = requests.get()

i thought there are no status codes returned from GraphQL server other than 200. You may need to inspect the result to contain error field.

How to pass variables?

How to pass variables?

Same question here. Do you know how to pass variables?

To pass variables---here queryString and maxItems---you can use format, e.g.

query = """
{{
   search(query: "{queryString}", type: REPOSITORY, first: {maxItems}) {{
     repositoryCount
     edges {{
       node {{
         ... on Repository {{
           name
           url
           stargazers {{ totalCount }}
         }}
       }}
    }}
  }}
}}
"""
variables = {
   'queryString' : 'is:public stars:>9999',
   'maxItems' : '5'
}

result = run_query(query.format(**variables))

To pass variables---here queryString and maxItems---you can use format, e.g.

query = """
{{
   search(query: "{queryString}", type: REPOSITORY, first: {maxItems}) {{
     repositoryCount
     edges {{
       node {{
         ... on Repository {{
           name
           url
           stargazers {{ totalCount }}
         }}
       }}
    }}
  }}
}}
"""
variables = {
   'queryString' : 'is:public stars:>9999',
   'maxItems' : '5'
}

result = run_query(query.format(**variables))

This unfortunately gives me a "KeyError: '\n trip(\n from'" when parsing this data: https://hastebin.com/buxivileha.makefile

Any idea why?

Because, you don't need to format the string .. you can pass both query and variables as separate keys in the json and the graphql endpoint can figure out what goes were

For anyone trying to pass variables for these queries, I suggest looking at string.Template in python:

from string Import Template
queryTemplate = Template(
"""{
  viewer {
    repositories(first: $num) {
      pageInfo {
        hasNextPage
        endCursor
      }
      edges {
        node {
          name
        }
      }
    }
  }
}"""
)

query = queryTemplate.substitute(num=n)

@Zylvian @deepaksisodiya

To pass in variables to the query you need to:

• add variables parameter in your run_query function.
• add variables key to the json you that is going to be appended to the graphql endpoint
• create the variables dictionary with the parameters you want to pass

my python is a bit rusty but this works

import requests

class graphQL:

	headers = {"Authorization": "token <token_here>"}

	"""docstring for graphQL"""
	def __init__(self):
		super(graphQL, self).__init__()

	def run_query(self, query, variables): # A simple function to use requests.post to make the API call. Note the json= section.
		request = requests.post('https://api.github.com/graphql', json={'query': query, 'variables': variables}, headers=self.headers)
		if request.status_code == 200:
			return request.json()
		else:
			raise Exception("Query failed to run by returning code of {}. {}".format(request.status_code, query))
	


	def getClosedIssuesActors(self):
		listOfNames = []
		query = '''
			query($owner: String!, $name: String!) { 
				repository(owner: $owner, name: $name){
				  issues(states: CLOSED, first:10){
					edges{
					  node{
						... on Issue{
						  timeline(last: 100){
							edges{
							  node{
								__typename
								... on ClosedEvent{
								  actor{
									login
								  }
								}
							  }
							}
						  }
						}
					  }
					}
				  }
				}
			}'''

		variables = {
  			"owner": "tatmush",
  			"name": "Saturday-THORN-Dev-Rank"
		}	

		result = self.run_query(query, variables) #execute query
		print(result)

don't forget to declare the variables in the query itself.

Thankkk youu!!!!!!!!!!!!!! You saved me:)

Here is an example using generators to overcome GitHub's a limit of 100 items/request.

I just noticed @tatmush use of variables. I used python's format_map, but variables keep the query string simpler.

Hi, same in Python2 (here to check which users as enabled Single Sign-On on an Organization)

Does anyone if it's possible to define variables inside fragments (see example below)?

        fragment repoQuery on Repository($states: [String!]) {
            pullRequests(first: 100, states: $states) {
                totalCount
                    nodes{
                        title

                }
            }
        }

Saved me hours of frustration.... Thank you!

Thanks, exactly what I needed! 👍

Thank you!

Awesome, thanks!

If you're using a Personal Access Token (PAT), you need to put the word "token" or "bearer" before the actual token:
headers = {"Authorization": "token XYZ123TOKENTOKENTOKEN"}

Thanks!

Hey, thanks for this post. Can we enable auto completion or graphiql like features while making these kinds of requests from notebook?
