Run a Python script to bulk-delete 3k invoices via Wave Apps API

I have a Wave Apps (waveapps.com) accounting account with 2,500+ invoices I need deleted. I already have a working Python script that uses Wave's GraphQL API to do this — I just need someone comfortable with Python and APIs to run it, verify it works correctly, and confirm the invoices are gone.

Scope of work:
- I'll provide a Python script (already written) and a Wave API token
- Install the one dependency (`requests`) and run the script
- First run in "dry run" mode to confirm it's targeting the correct invoices
- Then run for real, with a small subset first if you prefer, before doing the full batch
- Share the CSV log the script produces so I can confirm the results
- Flag any invoices that fail to delete (some invoices paid via Wave's online payment feature can't be deleted — these are expected to fail and that's fine)

Requirements:
- Comfortable with Python (able to edit a config section at the top of a script and run it from the command line)
- Basic familiarity with REST/GraphQL APIs
- Careful and communicative — this is a live business account, so I'd want confirmation before the full irreversible batch delete runs

Deliverable: confirmation the invoices are deleted, plus the CSV log file.

Estimated time: 30–60 minutes of actual work.


Note: I'll share the API token privately with whoever is hired, and will revoke it once the work is complete.
