🛠️ Usage

Example snippets of using the Subtopia JS SDK.

Subscriptions

Purchasing a subscription:

// ... your code

const response = await SubtopiaClient.subscribe(
  {
    subscriber: { address: {PUT_WALLET_ADDRESS}, signer: {PUT_WALLET_SIGNER} },
    smiID: { PUT_PRODUCT_ID_HERE }, // number - the ID of the SMI instance you want to subscribe to
    duration: { PUT_EXPIRATION_TYPE_HERE }, // pick duration from DurationType enum. If there is a discount available for this duration, it will be auto applied.
  },
  { client: {PUT_ALGOD_INSTANCE_HERE} // object of type algosdk.Algodv2
);

console.log(response.returnValue) // response is of type ABIResult

// ... rest of your code

Subscription lookup:

// ... your code
const subscriberBox = await SubtopiaClient.getSubscriptionRecordForAccount(
  client,
  { PUT_SUBSCRIBER_ADDRESS },
  { PUT_PRODUCT_ID_HERE }
);

// SubscriptionRecord (throws Error if not subscribed)
console.log(subscriberBox);
// ... rest of your code

Unsubscribing:

// ... your code
const deleteResult = await SubtopiaClient.unsubscribe(
  {
    subscriber: {
      address: { PUT_SUBSCRIBER_ADDRESS },
      signer: { PUT_SUBSCRIBER_SIGNER },
    },
    smiID: { PUT_INFRASTRUCTURE_ID },
  },
  {
    client: { PUT_ALGOD_CLIENT },
  }
);

// ID of the deleted subscription ASA
console.log(deleteResult.returnValue);
// ... your code

Transfering subscription:

// ... your code
const transferResult = await SubtopiaClient.transferSubscriptionPass(
  {
    newOwnerAddress: { PUT_NEW_OWNER_ADDRESS },
    oldOwner: {
      address: { PUT_OLD_OWNER_ADDRESS },
      signer: { PUT_OLD_OWNER_SIGNER },
    },
    smiID: { PUT_INFRASTRUCTURE_ID },
    subID: Number(result.returnValue),
  },
  { client: { PUT_ALGOD_CLIENT } }
);

// Transaction ID of the transfer transaction
console.log(deleteResult.txID);
// ... your code

Discounts

Creating a discount:

// ... your code

const discount = await SubtopiaClient.createDiscount(
  {
    creator: { address: {PUT_WALLET_ADDRESS}, signer: {PUT_WALLET_SIGNER} },
    smiID: { PUT_PRODUCT_ID_HERE }, // number - the ID of the SMI instance you want to subscribe to
    discount: {
      duration: DurationType // number - the type of expiration to apply. Also serves as static id for the discount.
      discountType: {PUT_DISCOUNT_TYPE_HERE} // number - the type of discount to apply. FIXED or PERCENTAGE
      discountValue: {PUT_DISCOUNT_VALUE_HERE} // number - the discount to be deducted from the subscription price
      expiresIn: {PUT_EXPIRATION_TIME_HERE} // (Optional) Set 0 for discount to never expire. Else set number of seconds to append to unix timestamp at time of creation.
    }, // number - the discount in percent
  },
  { client: {PUT_ALGOD_INSTANCE_HERE} } // object of type algosdk.Algodv2
);


console.log(discount.returnValue) // response is of type ABIResult

// ... rest of your code

Discount lookup:

// ... your code

const discount = await SubtopiaClient.getDiscountRecordForType(
  client,
  { PUT_PRODUCT_ID_HERE }
  { PUT_EXPIRATION_TYPE_HERE },
);

// DiscountRecord (throws Error if not found)
console.log(discount);
// ... rest of your code

Deleting a discount:

// ... your code

const deleteResult = await SubtopiaClient.deleteDiscount(
  {
    creator: {
      address: { PUT_SUBSCRIBER_ADDRESS },
      signer: { PUT_SUBSCRIBER_SIGNER },
    },
    smiID: { PUT_INFRASTRUCTURE_ID },
    duration: { PUT_EXPIRATION_TYPE_HERE },
  },
  {
    client: { PUT_ALGOD_CLIENT },
  }
);

// ID of the deleted discount ASA txn
console.log(deleteResult.txID);
// ... your code
