Given I have the below graph definition:

import requests
import json

@op
def get_api_endpoint(context):
	api_endpoint = context.op_config["api_endpoint"]
	resp = requests.get(api_endpoint)
    return resp.json()

@op
def save_json_data(json_data):
	with open("data.json", "w") as f:
		f.write(json.dumps(json_data))

graph_def = GraphDefinition(
    name='basic_api_call',
    node_defs=[get_api_endpoint, read_json_data],
    dependencies={'save_json_data': {'json_data': DependencyDefinition('get_api_endpoint')}},
)

How do i configure the api endpoint with the context using the graph definition class?

the easiest way would be calling

get_api_endpoint.configured

, which would allow you to directly specify what the API endpoint should be. Would that fit your use case?

interesting, ill try this out
