What this workflow does

This workflow has 20 nodes and runs manually, when you click “Execute workflow” (plus 1 other trigger). It uses only n8n's built-in nodes.

How it runs

Trigger: Manually, when you click “Execute workflow” (plus 1 other trigger).

1. Get file (HTTP Request): calls an HTTP API
2. hasFile (If): checks a condition and branches into true / false
3. Convert file to base64 string (Extract from File): extracts data from a file
4. Convert to File: converts data to a file
5. No file Error (Stop and Error): stops the run with an error
6. Upload file (Execute Sub-workflow): calls another n8n workflow
7. getFileSizeInBytes (Code): runs custom JavaScript code
8. createSession (HTTP Request): calls an HTTP API
9. Merge: merges the data from its input branches
10. isGraterThenMax (If): checks a condition and branches into true / false

…plus 8 more steps. See the full node list below.
