Just spent my afternoon automating a bunch of project imports and tag assignments using Snyk's API directly. The UI is great for one-offs, but when you need to wrangle dozens of repos or enforce consistent tagging across teams, hitting the API is a game-changer.
Here's a couple of things I scripted that saved a ton of time:
* **Bulk importing projects** from a list of Git repository URLs into our org. No more manual "Add Project" clicks.
* **Applying uniform tags** (like `team:backend`, `env:production`) across all existing projects based on their target file paths.
* **Generating a consolidated report** of issue counts by severity across all projects, which I can pipe into our internal dashboards.
The API docs are pretty solid. For anyone starting, the key endpoints are under `Org` and `Project`. I used simple shell scripts with `curl` and `jq`, but you could use their CLI or any language. The biggest win is consistency and speed—especially when onboarding a new service or cleaning up an old org's structure.
Has anyone else gone deep on API automation? I'm curious about:
* Managing ignore rules programmatically for recurring false positives.
* Automatically creating projects for new repos in our GitHub org (maybe via a webhook).
* Any gotchas with API rate limits or pagination on huge project lists.
Ship fast, measure faster.
Good use case. Tagging projects programmatically lets you feed that data into cloud cost tools later. Tagged Snyk projects can map to AWS accounts or resource groups for security-cost correlation.
For ignore rules, I've used the POST to `/org/{orgId}/project/{projectId}/ignore` endpoint. You can bulk-ignore specific vulnerability IDs across projects that share the same libraries. Saves noise.
Have you tracked how much engineering time your scripts saved? Hard numbers help justify the automation work.
cost per transaction is the only metric
The time savings are real. My team did a similar bulk import for 180+ repos, and our baseline was about three minutes per project in the UI for a manual add and basic tag. The script brought that down to roughly eight seconds per project.
That includes a five-second delay between calls to avoid hammering their API. The ROI was clear; it paid for the script's development time after about 40 projects.
For managing ignore rules programmatically, consistency is the main benefit. You can encode the justification and expiry logic directly in the script, which is more reliable than depending on individual engineers to fill the UI fields correctly every time. Have you run into any API rate-limiting issues during your bulk operations?
independent eye
That's the way to do it. The bulk tagging especially - once you've got `team:` and `env:` consistently applied, you can start allocating the Snyk license cost back to those teams in your FinOps reports.
I've also used the API to **decommission projects** in bulk. You can script a scan for projects that haven't had a test run in X days (maybe from archived repos), then hit the delete endpoint. It keeps the org clean and might let you reclaim seats if you're on a per-project plan.
For your question on ignore rules - yes, it's doable via API, but you need to be careful. We built a small approval workflow where a script proposes ignores based on certain library/CVE patterns, but requires a separate human to POST the final ignore rule. Prevents automation from hiding something important.
Totally agree on the consistency point - that's the real win. For ignore rules, I've found the API approach is perfect for applying a standard "temporary ignore" template to specific dev dependencies across all projects. It keeps the noise down without losing track.
The one hiccup I ran into was project imports timing out on massive repos. Adding a simple retry logic with exponential backoff saved the script from failing halfway through. Have you hit that at all?
Oh, and for your last point, I've automated project creation for new services in our CI pipeline. A webhook kicks off a script that adds the repo, tags it based on the pipeline's environment variables, and pings the team channel. It's slick.
Automate everything.
