Billing API

Topic summary

Question about integrating Shopify’s Billing API for an app submission, specifically the GraphQL mutation appSubscriptionCreate used for app subscription charges. The main unresolved point is whether the Billing API can be implemented in PHP and where to find a clearer step-by-step guide, as the available documentation was described as insufficient.

Current outcome:

  • No technical implementation details or PHP example were provided in the discussion.
  • The request was redirected because the post was made in a forum section meant for Shopify Subscriptions APIs, not general API support.
  • Two documentation/resources were pointed out:
    • Shopify Billing API docs: shopify.dev/apps/billing
    • General Shopify APIs forum section for billing-related questions.

Status: unresolved and ongoing. The conversation did not answer the PHP compatibility question directly, and the next suggested action is to consult the Billing API documentation or repost in the broader Shopify APIs forum for more specific support.

Hi!

We’re currently trying to add Shopify Billing API to submit our app to the Shopify marketplace, but we cannot find enough instructions on this. We are checking https://shopify.dev/api/admin/graphql/reference/billing/appsubscriptioncreate We’re checking the GraphQL Billing API.
Could you please help us with it? Do you have any detailed, step-by-step tutorials? The information provided is not enough, unfortunately.

The most important question is: Can we configure the API in PHP?

Thanks in advance!

Kind Regards,
Vasili
