Retrieve output data from a previous block in a code block

[Luis_Miguel_Escudeir]

Hello everyone

Sorry for this silly question, I’m starting with n8n with zero skill in Java so trying to make my way through :frowning

I’m trying to build a scenario with multiple nodes executed that will retrieve some data via api and now I need to bundle everything in a code block before I make a global call to a third party API.

My code block needs to perform two things :

1. Format the body with data coming from previous nodes
2. Wrap multiple items under a “transactions” array.

I have been able to sort out the second piece via search on the forum and found a code block for this.

Now I’m struggling with something quite simple for the 1).

Basically I want to be able to retrieve data from previous nodes as shown below - in my case I just want to be able to retrieve the field label from the node ‘Identity current account’

The transactions loop below is already ready and working.

Can someone guide me in the correct direction?

Thanks a lot

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Sure sorry (even though not so sure how to retrieve this information as we are embedding n8n into our solution so I guess it’s an “enterprise” version ?)

• Database (default: SQLite): 1.33.1
• n8n EXECUTIONS_PROCESS setting (default: own, main): Sorry I don’t know as this is governed by the devOps team (Can provide the instance id if it helps ?)
• Running n8n via (Docker, npm, n8n cloud, desktop app): Docker on enterprise version I guess (at least I do see n8n Enterprise Licence on the about n8n screen)
• Operating system: don’t know sorry would have to check with devops team if this is mandatory

hi,

here’s a sample for how you can access the previous nodes data.Added screenshot

if you know that previous node returns just 1 item,
$input.first().json.variable_name

if it returns multiple items
you can for loop the $input.all() as shown in the screenshot, if you need to access a specific item.
