B2B API companyAssignCustomerAsContact issue

[BojanAnchev]

I'm having trouble executing this API GraphQL mutation: companyAssignCustomerAsContact

I have a company and customer created but I cannot create/assign that customer as a contact to that company I was following the documentation and tried implementing it with Python.

import json
import requests

def assign_customer_as_contact(url, access_token, companyId, customerId):
    # Define the GraphQL mutation
    mutation = """
mutation {
  companyAssignCustomerAsContact(
    customerId: "gid://shopify/Product/your_contact_id"
    companyId: "gid://shopify/Product/your_company_id"
  ) {
    userErrors {
      field
      message
    }
  }
}
    """

    # Prepare the variables for the mutation
    mutation = mutation.replace('your_contact_id', customerId)
    mutation = mutation.replace('your_company_id', companyId)

    print(mutation)
    # Setup headers for the request
    headers = {
        "Content-Type": "application/json",
        "X-Shopify-Access-Token": access_token,
    }

    # Setup the request payload
    payload = {"query": mutation}

    # Send the request to the Shopify GraphQL API
    response = requests.post(url, headers=headers, json=payload)

    # Handle the response
    if response.status_code == 200:
        data = response.json()
        if "errors" in data:
            print("Error:", data["errors"])
        else:
            print("Customer assigned as contact successfully.")
            print(json.dumps(data["data"], indent=2))
    else:
        print("Failed to assign customer as contact.", response.text)

if __name__ == "__main__":
    api_url = ''
    api_access_token = ''

    company_id = "3131"
    customer_id = "3131"

    # Call the function to assign customer as contact
    assign_customer_as_contact(api_url, api_access_token, company_id, customer_id)

I got the following error:

Error: [{'message': 'invalid id', 'locations': [{'line': 3, 'column': 3}], 'path': ['companyAssignCustomerAsContact']}]

What am I doing wrong I assume they are referring to these customers.

Hey @BojanAnchev,

I see your script is replacing the legacy resource ID, the number at the end of the Shopify Global ID value, but both arguments to the mutation are set as Products rather than a Customer and a Company: 

companyAssignCustomerAsContact(
    customerId: "gid://shopify/Product/your_contact_id"
    companyId: "gid://shopify/Product/your_company_id"
  ) 

Looks like our documentation for that mutation has Products listed as placeholder variables as well, so I've already sent some feedback to request the docs be updated. 

All the best!

@ShopifyDevSup thank you, this resolved the issue.
