POST a Turbo Transaction

20min
Prerequisites
Before submitting an API request, ensure you have completed the following:
Create an Account
Create a Project
Installed the Eternl wallet﻿
You need a Maestro Composer-level subscription or higher to access the Turbo Transactions feature. Otherwise, you can use the Submit Transaction endpoint.
﻿
Steps to Submit an API Request 
Turbo Transactions supercharge your transaction submission processes. This guide will walk you through generating a transaction on Eternl and sending it to Maestro's Turbo Transaction endpoint.
﻿
1. Prepare Your Wallet
Switch the network to Pre-Production Testnet by selecting it from the bottom-right selector of the Eternl wallet interface.
﻿
﻿
Create or restore two separate wallets  in Eternl to test the transaction. 
﻿
After creating the wallets, disable the Transaction Auto Submit option.
﻿
﻿
Find your wallet address in the Eternl dashboard under the Receive tab.
﻿
Send test ADA (tADA) to one (or both) wallets using the Cardano Faucet﻿ here.
﻿
﻿
2. Configure Eternl to Use Maestro's Turbo Submit Endpoint
Open Eternl App Settings
﻿
Expand the Custom Submit API Endpoint section and click Add 
﻿
Enter the below Turbo Transaction Submit API URL, replacing <API_KEY> with your project key found in your project dashboard.﻿
Text
https://preprod.gomaestro-api.org/v1/txmanager/turbosubmit?api-key=<API_KEY>
https://preprod.gomaestro-api.org/v1/txmanager/turbosubmit?api-key=<API_KEY>
﻿
﻿
 Click Save
If your subscription does not support Turbo Transactions, you can try the standard Submit API.
Upgrade to the Pay-as-you-go Conductor subscription for easy access and support for Turbo Transactions.
﻿
3. Generating a Transaction
Go to the Send tab
Enter the receiving wallet address to create and sign a transaction between the two test wallets. Then, specify the amount of test ADA to send.
﻿
Enter your spending password and click Sign.
﻿
﻿
4. Submit the Transaction
Option 1
Click Submit to hit the Turbo Transaction endpoint via Eternl.
﻿
Option 2
Click Download(signed)
﻿
Copy the cBorHex from the downloaded transaction file. In this example, that will be:
