The following steps are needed to fetch all sticker packs: + #### 1. Get total number of sticker packs Call `packCount()` on the sticker market contract, will return number of sticker pack registered as `uint256`. + #### 2. Get sticker pack by id -ID's are represented as `uint256` and are incremental from `0` to total number of sticker packs in contract, which we received on previous step. To get a sticker pack we should call `getPackData(sticker-pack-id)`, the return type is `["bytes4[]" "address" "bool" "uint256" "uint256" "bytes"]` which represents the following fields: `[category owner mintable timestamp price contenthash]`. Price is the SNT value in wei setted by sticker pack owner. The contenthash is the IPFS address described in the [submit desction](#submit-a-sticker-pack) above. Other fields specification could be found in [Sticker Market spec](https://github.com/status-im/sticker-market/blob/651e88e5f38c690e57ecaad47f46b9641b8b1e27/docs/specification.md) +ID's are represented as `uint256` and are incremental from `0` to total number of sticker packs in contract, which we received on previous step.

Get owned sticker packs The current Status app fetches owned sticker packs during the open of any sticker view (a screen which shows a sticker pack or the list of sticker packs). To get owned packs, we should get all owned tokens for the current account address. To do that we should call `balanceOf(address)` where address is the address for current account. This method returns a `uint256` representing the count of available tokens. Using `tokenOfOwnerByIndex(address,uint256)` method, with the address of the user and ID in form of a `uint256` which is an incremented int from 0 to total number of tokens, we will get token id. To get sticker pack id from token we call`tokenPackId(uint256)` where `uint256` is the token id. This method will return an `uint256` which is the id of the owned sticker pack. ##### 4. Buy a sticker pack To buy a sticker pack we should call `approveAndCall(address,uint256,bytes)` where `address` is the address of buyer,`uint256` is the price and third parameters `bytes` is the callback called if approved. In callback we call `buyToken(uint256,address,uint256)`, first parameter is sticker pack id, second buyers address, and the last is the price. + ## Copyright Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/).
