Getting Started#

Create a workflow to Sign a transaction with the Overledger API. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Configure the Sign a transaction action
1. Connect your Overledger account
2. Select a Overledger Instance
3. Select a Location Technology
4. Configure Signing Account ID
5. Configure Request ID
6. Configure Transaction Signing Responder Name
7. Configure Native Data
Select a trigger to run your workflow on HTTP requests, schedules or app events
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Overledger	`overledger`	`app`	This component uses the Overledger app.
Overledger Instance	`environment`	`string`	Select a value from the drop down menu:`{ "label": "Sandbox", "value": "sandbox" }{ "label": "Overledger", "value": "overledger" }`
Location Technology	`locationTechnology`	`string`	Select a value from the drop down menu:`{ "label": "Ethereum", "value": "ethereum" }{ "label": "Substrate", "value": "substrate" }{ "label": "XRP Ledger", "value": "xrp ledger" }{ "label": "Bitcoin", "value": "bitcoin" }{ "label": "Hyperledger Fabric", "value": "hyperledger fabric" }`
Signing Account ID	`keyId`	`string`	The ID/address of the blockchain account that will sign the transaction.
Request ID	`requestId`	`string`	The Request ID assigned to a preparation request in Overledger. This should be set to the requestId parameter found in the response object of the 'Prepare Transaction' Overledger action.
Transaction Signing Responder Name	`transactionSigningResponderName`	`string`	The name of the Transaction Signing Responder you would like to use. The CTA Transaction Signing Responder is the Quant-provided signer for testnet accounts.
Native Data	`nativeData`	`object`	An object representing the transaction required to be signed - This should be set to the nativeData object of the 'Prepare Transaction' Overledger action.

Authentication#

Overledger uses OAuth authentication. When you connect your Overledger account, Pipedream will open a popup window where you can sign into Overledger and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Overledger API.

Pipedream requests the following authorization scopes when you connect your account:

overledger/read.scope
