In magento2 - I have created one extension attribute for customer using plugin, it's working fine for Rest API also. How can I include this extension attribute in GraphQL?

In createCustomer mutation , all the CustomerInput are added. Can anyone help me in adding an extension attribute to this mutation?

  • Did you try to pass that attribute in the CustomerInput, i am asking this based on the product Attribute, If we create a custom product attribute we can get the value by just passing the attribute_code in the query. – Mujahidh Oct 16 '19 at 5:24
  • How can I extend the CustomerInput in vendor ? – Kavi Oct 16 '19 at 5:35
  • Can you just elaborate on this? – Kavi Oct 16 '19 at 5:36
  • you just pass your new attribute in CustomerInput and see, but currently CustomerInput only have prefix,firstname,middlename,lastname,suffix,email,dob,taxvat,gender,password,is_subscribed fields.if passing the attribute to the mutation not work you have to write your own module to add the attribute and do some work arround in Magento\\CustomerGraphQl\\Model\\Resolver\\CreateCustomer in your own module. – Mujahidh Oct 16 '19 at 5:43
  • study the module-customer-graph-ql in vendor/magento directory. – Mujahidh Oct 16 '19 at 5:44

All you have to do is re-define the 'CustomerInput' parameter (with your custom extension attribute) of the createCustomer mutation.

In your module's schema.graphqls file, re-define the 'CustomerInput' type.

input CustomerInput {
    your_extention_attr: String

Then run the below commands.

rm -rf generation/

bin/magento c:f

Now you can parse this new parameter in createCuatomer mutation. See the example below.

mutation {
    input: {
      firstname: "Bob"
      lastname: "Loblaw"
      email: "bobldsdd2@example.com"
      password: "b0bl0bl@w"
      is_subscribed: true
      your_extention_attr: "this is a test value"
  ) {
    customer {
  • this way not working for me... – prabhakaran7 Dec 17 '19 at 5:43
