How to pull the response from HTTP Request Node POST response to another node/module

Questions
1

I am creating multiple HTTP Request and those POST returns response

"response": 
"[\n  {\n    "contacts": [\n      {\n        "id": "j3213213213",\n

I need to capture the response or want to pull the ID from the response since I need to use that to another HTTP Request Node

Example
Node 1 - Get ID
Node 2 - Update Contact

In Node 2, I need to define the ID but not sure how to pull the response from Node 1

I am also using AI Agent

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:

if you just need a part of the response to be sent to the agent,
the quckest and easiest option would be setup a sub workflow do the HTTP thing, put a edit field node, then only pass that to next step,

and call the sub workflow to the agent

Thanks How do I store and retrieve that data to be sent to another node that I got from a sub workflow
For example, I received the ID from the subworkflow, where or what variable can it be stored to. in the book_appointment I have a json like but not sure what to put in the contactId

{
  "calendarId": "{calendarId}",
  "locationId": "{locationId}",
  "contactId": "",   //ContactId
