Common API Usage (Important !)

FST Engine API utilises GraphQL to make complex data-integrations agiler, type-safer and clearer
- Please check and try immediately in your FST Engine GraphQL Playground provided by FST Network
Please don’t forget to set Authorization http header via Auth before performing the operations that need to be authorised (also in GraphQL Playground)
There are 3 common types of APIs in FST Engine: READ, CREATE and TRANSACT
- READ indicates that the operation reads data from Accountable Data Network (FST DataRail)
- CREATE indicates that the operation creates data (e.g. Smart Contracts, Ledgers) to Accountable Data Network (FST DataRail)
- TRANSACT indicates that the operation updates data to Accountable Data Network (FST DataRail)
The APIs in CREATE type and TRANSACT type mostly require the Transaction Signing process with the API response
- Please see more details at signTransactionExample
As for READ API, the pagination in this type of API follows the principle of GraphQL cursor-based pagination
- In short, the pageInfo.endCursor in the response for current page will be the after in next page API call. And the first is equal to the limit in common databases usage
