okay fix it but now i got this Error: Variable $name of type String! was provided invalid value

That sounds like a typescript error whereby that variable is expecting a string and got something else. If you go for the JavaScript version of the starter it will probably be easier to work with

@@MarkCodesTH-camMh okay thanks for reply. But yes i have choice Javascript.

I think this should help shopify.dev/docs/apps/launch/billing/support-one-time-purchases

If your app creates data they might find useful to keep them if you delete that on install they have to set it all up again if they do that

If you have your app set to delete user data from your database on uninstall (which you should) then whilst a user could keep installing and reinstalling after a free trial they would have to add all their data again so it's unlikely they will

@@MarkCodesTH-cam Thanks but this will create a loop which can uninstall the app on last day of free trial and reinstall it, i was thinking to keep in database if was installed before, so based on this to redirect to the subscription plan page

No reason at all...you could equally use the billing object

@@MarkCodesTH-cam ah good. Wasn’t sure if there might have been a reason. On something slightly different - do you know if it’s possible to get the current usage of a usage based plan? I cant seem to find any GraphQL objects with the current usage. I’m thinking I just have to keep track of it myself.

Do you mean how many people are subscribed to an app?

@@MarkCodesTH-cam no sorry, I mean in terms of usage based billing for the merchant. Shopify keeps track of the usage records that have been created, and the merchant can check this in Admin>Billing. I just don’t seem to see a way to retrieve that data. Will have another look at it tomorrow, but just wondered if you knew of it or not?

@dan110024 I’m still not quite sure if I get you but in your partner account for the app you can see install and uninstall history and payments etc

Yes, the 2nd video with the meta fields based on billing status is on this channel

For that you're not going to want an app metafield you're going to want to programatically create a new one using graphql and CreateMetafieldDefinition shopify.dev/docs/api/admin-graphql/2024-01/mutations/metafieldDefinitionCreate - This will only create that metafield if it doesn't exist already and this will be accessible. It sounds like you'll then need to do something when a user orders to add the data to the metafield for that order (not too sure how to do that!)

@@MarkCodesTH-cam I will try it and let you know when I manage to do it! Thanks for the response and for this awsome video and keep up with these kinds of videos. The docs are terrible and this helps a lot!

This is the query that created the field for all orders. I'm planning to run it when the user installs the app so the metafields definitions are created and available. const response = await graphql( ` #graphql mutation CreateMetafieldDefinition( $definition: MetafieldDefinitionInput! ) { metafieldDefinitionCreate(definition: $definition) { createdDefinition { id name namespace } userErrors { field message code } } } `, { variables: { definition: { name: "Test field for pinned metafield", namespace: "$app:pinned", key: "pinnedField", description: "A list of ingredients used to make the product.", type: "multi_line_text_field", ownerType: "ORDER", access: { admin: "MERCHANT_READ_WRITE", }, pin: true, }, }, }, );

I'm not sure what you mean by sharing password of the billing. If you were going to have a 2nd plan you'd probably need some kind of plan management section of your app but you could use the metafield outlined in this video and the billing setup outlined in my previous one to setup a checkout extension billing plan and use a metafielcd to conditionally show that extension...if that makes sense?

@@MarkCodesTH-cam sorry incorrect word. I mean if you have a sample of the code you used on video so its easier to copy it like on github.

Does the extension appear in your app settings when you log in as a partner? It could be that the extension hasn't been published

@@MarkCodesTH-cam yes it shows under extensions in partner account

@@ajhax4707 That's odd...what does the schema for your extension look like?

This is our star_rating.liquid file

Not all metafields...so the app specific metafield I show in this video cannot be updated by the shop owner, only in code

I've got a billing video coming out today...you don't actually need to save it in the database you can check via GraphQl and subscribe to a web hook!
