1/ HTTP Request Node
this is your gateway to connect with any API
basic setup:
- method: GET/POST/PUT
- URL: the API endpoint
- headers: usually "Content-Type: application/json"
- body: your data payload
master this node and you can connect n8n to literally anything

think of it as "if this happens, do that"
setup:
- condition type: string, number, boolean
- operation: equal, contains, greater than
- value 1: the data you're checking
- value 2: what you're comparing it to

master these 20 nodes and you can build 95% of business automations
(let me know if i forgot one)
start with the first 5:
- HTTP Request
- IF
- Set
- Gmail
- Google Sheets
then gradually add the others as you need them
don't try to learn all 200+ nodes at once
focus on these core ones and you'll build some great automations
