The send statement is the main and most powerful stage of the Workflow definition. It allows you to natively send money from a payment to a ledger account, from a ledger account to a wallet and from a wallet to a payment initiation, handling the implementation of the actual underlying semantics. It can be added to a Workflow definition by creating a new stage with the send type: 
---
stages:
- send:
    source:
      # ...
    destination:
      # ...
    amount:
      amount: 100
      asset: "EUR/2"
The send statement is composed of three main attributes:
  • source: the source of the funds to be sent
  • destination: the destination of the funds to be sent
  • amount: the amount of funds to be sent
The source and destination parts can reference either a ledger account, a wallet or a payment.

[1] The send statement can be used with a payment block as the destination, which will initiate a payment to the PSP defined in the psp attribute. This is currently supported only for the stripe connector, though support for other connectors will be added in the future.

Source types

​
Ledger account

A ledger account can be referenced by providing the account attribute, which is composed of the id and ledger attributes, referencing the account address and the ledger name respectively: 
---
stages:
- send:
    source:
      account:
        id: "users:42"
        ledger: "flows-demo-001"
    destination:
      # ...
    amount:
      # ...

​
Wallet

A wallet can be referenced by providing the wallet attribute: 
---
stages:
- send:
    source:
      wallet:
        id: "22d5de50-b5ef-407d-9a03-9e4fc36356f8"
    destination:
      # ...
    amount:
      # ...

​
Payment

A payment can be referenced by providing the payment attribute: 
---
stages:
- send:
    source:
      payment:
        id: "22d5de50-b5ef-407d-9a03-9e4fc36356f8"
    destination:
      # ...
    amount:
      # ...

​
Destination types

​
Ledger account

A ledger account can be referenced by providing the account and ledger attributes: 
---
stages:
- send:
    source:
      # ...
    destination:
      account:
        id: "users:42"
        ledger: "flows-demo-001"
    amount:
      # ...

​
Wallet

A wallet can be referenced by providing the wallet attribute: 
---
stages:
- send:
    source:
      # ...
    destination:
      wallet:
        id: "22d5de50-b5ef-407d-9a03-9e4fc36356f8"
    amount:
      # ...

​
Payment

Beyond the syntax, it’s important to understand the effective behaviour of defining a payment block as the destination of a send statement. Here, we won’t reference a payment by its identifier (as it doesn’t exist yet), but rather the connector we want to use to initiate a payment. This is done by providing the psp attribute: 
---
stages:
- send:
    source:
      # ...
    destination:
      payment:
        psp: "stripe"
    amount:
      # ...
The send statement will create a payment initiation request to the PSP defined in the psp attribute. The payment initiation request will be sent to the PSP with the amount and asset defined in the amount attribute.
