Create New Transfer Flow

To initiate the transfer process, create a new flow with a POST request to /flows.

URL

https://api.figment.io/flows

Request

protocol* : string Protocol this flow operates on (ex. polkadot).
network* : string Network this flow operates on (ex. westend).
operation* : string The operation to perform (ex. transfer).

{
  "protocol": "polkadot",
  "network": "westend",
  "operation": "transfer"
}

Response

id : string ID of the flow.
operation : string The Staking API operation being performed by this flow.
state : string The current state of the flow.
actions : array It includes the name & inputs of all next possible actions.
- create_transfer_tx : Use this action to create a transfer transaction to send DOT between accounts.
  - from_account_address : The address from which DOT will be transferred.
  - to_account_address : The address to which DOT will be transferred.
  - amount : The amount of DOT to be transferred.
data : object Flow & transaction data.

Submit Transfer Data

After collecting the required inputs, send a PUT request to /flows/[:flow_id]/next to proceed to the next step.

URL

https://api.figment.io/flows/[:flow_id]/next

Request

name* : create_transfer_tx
inputs* : object
- from_account_address* : string the address from which DOT will be transferred.
- to_account_address* : string The address to which DOT will be transferred.
- amount* : number The amount of DOT to be transferred.

Submit Signed Transfer Transaction for Broadcast

Before broadcasting the transaction, you must sign the transaction_payload you received in the previous step. After signing the transaction, send a PUT request to /flows/[:flow_id]/next with the signed payload. The Staking API will broadcast the transaction to the Polkadot network.

URL

https://api.figment.io/flows/[:flow_id]/next

Request

name* : sign_transfer_tx
inputs* : object
- transaction_payload* : Signed transaction payload from the previous step's response.
- signatures : array of object The signatures array can be used instead of sending a transaction payload when the signing keys are kept in a custodial solution, such as Fireblocks. Refer to the guide Signing Transactions with the Fireblocks API for details.
