How can I correctly use GraphQL in a webhook?

Shopify Apps

I’m adding a webhook, and in that webhook I want to make a graphql call to modify an order.

export const action = async ({ request }) => {
const { payload, topic, shop, session, admin } = await authenticate.webhook(request);

switch (topic) {
…
case “CHECKOUTS_CREATE”:
if (admin) {
admin.graphql.query(query here...)
}
…

I assumed that I could use the graphql client here, but I get a TS error Argument of type 'string' is not assignable to parameter of type 'GraphqlParams'.

What is the right way to do this?

OK, so for some reason the admin.graphql that comes back from authenticate.webhook is different than what comes back from authenticate.admin. If I pass {data: "query here..."} this works. Now I just need to craft the right query.

I’m getting the same issue. Would you mind sharing the docs you refer to / what was your solution?

Thanks!

if anyone is facing the same issue, here’s what works for me:

isHook - true if it’s from webhook’s admin, false if it’s from the web admin.

const response = this.isHook
? await this.graphql.query({ data: { query, variables } })
: await this.graphql(query, { variables });

I have spent so long trying to figure out how to make admin graphQL calls from a webhook, and your answer solved it. Sincerely, thank you so much for sharing.

PS: Why there doesn’t seem to be anything about this in the docs is beyond me!

Damn, thanks man. I really hate Shopify’s docs.

inside yourAppName/app/routes/webhooks.jsx

case "CHECKOUTS_CREATE":
  if (session) {
    const response = await admin.graphql.query({data: `
      query {
        shop {
        name
      }
    }`
  });
}
break;
