Data Mapping

Data mapping lets you reference data from previous blocks in your current block. When Block 1 returns a user ID, Block 2 can use it in its URL — automatically.

​
How it works

  1. Run a block — the response data becomes available as variables
  2. Type {{ in any field (URL, headers, body, auth) — the autocomplete dropdown appears
  3. Pick a value — it inserts the variable reference
  4. When the flow runs — the variable resolves to the actual value from the previous block’s response

​
Autocomplete

Type {{ in any input field to open the variable picker:
  • Previous block responses — body fields, status, headers
  • Environment variables — baseUrl, apiKey, etc.
  • Email block values — extracted OTP, email subject, from address
Each suggestion shows the actual value from the last run, so you know exactly what you’re selecting. Autocomplete dropdown

​
Variable syntax

Variables use double curly braces: {{source.path}}

​
From previous blocks

{{node_abc123.body.id}}          → response body field
{{node_abc123.body.user.email}}  → nested field
{{node_abc123.status}}           → response status code
{{node_abc123.headers.x-token}}  → response header

​
From environment variables

{{baseUrl}}     → environment variable
{{apiKey}}      → environment variable
{{testEmail}}   → environment variable

​
From email blocks

{{node_email1.value}}     → extracted value (OTP, link, etc.)
{{node_email1.subject}}   → email subject
{{node_email1.from}}      → sender address

​
Example

Block 1: Create User 
POST {{baseUrl}}/users
Body: {"email": "test@example.com", "name": "John"}
Response: {"id": "usr_123", "email": "test@example.com"}
Block 2: Get User (references Block 1’s response) 
GET {{baseUrl}}/users/{{node_block1.body.id}}
→ resolves to: GET https://api.example.com/users/usr_123
You don’t need to memorize node IDs. The autocomplete dropdown handles this — just type {{ and pick the value you need.

​
Where variables work

Variables are supported in:
  • URL field
  • Header values
  • Request body
  • Auth token / API key values
