#### Install a sticker pack
To install a sticker pack, we need to fetch all sticker packs which are available in Sticker Market. 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)

##### 3. 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.
