Upload Large Files to Kommo/AmoCRM with Auto Chunking

This n8n workflow enables seamless uploading of large files from any source to Kommo or AmoCRM accounts. It handles file availability checks, downloads via session, automatic chunking for oversized files, and sequential uploading of parts to CRM fields, chats, or notes.

Key advantages include support for both Kommo and AmoCRM, minimal parameters (drive_url, file_name, file_base64), and robustness for large files that exceed API limits. It saves time by automating complex file handling, reducing manual uploads and errors.

Ideal use cases: Sending files in client chats, attaching to transactions/contacts, or adding to notes. Installation is straightforward: import the workflow, set up OAuth2 credentials, apply to nodes, input file details, and execute. Perfect for sales teams streamlining CRM interactions.
