Associate SubscriptionDraft to SubscriptionContracts

[bomanys]

So I'm currently building an app for managing subscriptions on shopify but I'm not understanding the Subscription Drafts. I've already been able to create them modify and commit them but how do I associate them to a contract? How can I modify an existing contract? (Ex: How to pause/cancel a contract?)

When you commit a subscription draft the changes are applied to the contract itself. If there is no contract, a new one will be created: https://shopify.dev/api/admin/graphql/reference/orders/subscriptiondraftcommit

To get a contract draft from an existing contract you can use the subscriptionContractUpdate mutation: https://shopify.dev/api/admin/graphql/reference/orders/subscriptioncontractupdate#interactive-exampl...

You can get more information on this here: https://shopify.dev/apps/subscriptions/contracts

Hi, I am able to create a Subscription contract draft, with subscriptionContractCreate mutation. I get the draft id & I immediately would like to commit it because i am creating a new contract, but I get {"data"=>{"subscriptionDraftCommit"=>{"contract"=>nil}} a nil contract with no errors at all. several attempts still return nil. What am I doing wrong? Please help me out.

I am also facing this error? Could anybody help out from these error?

In my case, I am getting errors like these:


[
{ code: 'INVALID', field: null, message: 'is invalid' },
{
code: 'INVALID_LINES',
field: [ 'draftId' ],
message: 'Contract draft must have at least one line.'
}
]

Please help @ThomazReis !!!
