Contract API offers the following features.

Register, query, and modify contract resources
Deploy, query, modify contract and execute contract methods

Pre-requisites: Get API Authentication Token

To call a Contract API, you have to append an auth token to the header of an API. This is how to get your API auth token.

Sign up at the Hive Console, go to AppCenter > Game List > Register new game.
Create an new AppID at AppCenter > AppID List > Register new AppID.
- Register new AppID: Web Login AppID
- Purpose of use: Blockchain
- AppID to use:Choose “automatically generated AppID” or “automatically generated AppID” with “Additional Information”
Go to the the Hive Console > Blockchain > Search for API Authentication Key, select and search the game name, and get the ID and the Secret key.
Insert the ID and the Secret key in the request body of auth-token API and call this API.
You can get your API auth key as data.accessToken in the API responses.

Register Contract Resources

Registers the resources of a contract. Register the contract name (contractName), the contract description (contractDesc), and the bytecode and ABI/Scheme generated after the contract is compiled.

In general the contract methods are divided into 2 types: the query type and the execute type. The query type method just queries the data, and the execute type method writes new data in the contract or modifies the existing data in the contract. The execute type always returns the raw transaction, not like the query type.
