One API call.
A real tree
in real ground.

Pick a subscription plan

Your plan sets your API allowance, your branding options, and your per-impact price. No contracts — switch tiers or cancel whenever, and billing adjusts immediately.

Sandbox access, dashboard tracking, digital certificates, and customer impact emails are included on every plan — including Free.

Billing runs on a monthly subscription cycle, and impact is billed against that cycle — which is why the donation_available timestamp follows your billing date, not your API call date.

Get your keys, build in sandbox

Your API keys are waiting in your dashboard and the full documentation is available. Two environments, one header authenticates both.

Sandbox is a full mirror of production. Same endpoints, same shapes, same responses. The differences are deliberate:

Build your whole integration here. Confirm your key works with a single call:

curl https://sandbox.1clickimpact.com/v1/whoami \
  -H "x-api-key: test_YOUR_KEY"

{
  "user_id": "U123",
  "email": "you@yourcompany.com"
}

If that comes back, you're connected.

Test in production, safely

Sandbox covers most of what you need. But sometimes you need to validate the real thing — live email delivery, the actual dashboard, your own analytics pipeline — without paying for impact you didn't mean to create.

Email contact@1clickimpact.com or your account manager with your account email, and we'll temporarily flag you as a Test Account.

When you're ready to go live, tell us and we'll switch the flag off. Nothing in your code needs to change.

The API in 60 seconds

REST over HTTPS. JSON in, JSON out. One header for auth. No SDK required — though we're glad to help you wire one up.

Create impact

All four creation endpoints share the same optional fields — integrate one and you've integrated all of them:

curl -X POST https://sandbox.1clickimpact.com/v1/plant_tree \
  -H "x-api-key: test_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "amount": 5,
    "customer_email": "customer@example.com",
    "customer_name": "Alex Rivera",
    "category": "food",
    "notify": true,
    "metadata": { "order_id": "ORD-456" }
  }'

{
  "user_id": "U123",
  "tree_planted": 5,
  "time_utc": "2026-07-29T20:34:04.429Z"
}

Refunds are handled cleanly

POST /v1/cancel_impact takes the user_id and time_utc of the original impact, removes it from your totals, and reverses the billing. It's idempotent, so retries are safe, and the original record is preserved for audit. Impact already delivered to a nonprofit can't be cancelled by API — reach out and we'll sort it.

Read your data

Live planting sessions

Watch your trees go into the ground. Ask the farmer a question.

Pass one extra field and you unlock the thing nobody else offers.

"category": "food"

Food trees are fruit- and nut-bearing trees planted with farming communities. They don't just sequester carbon — they produce food and ongoing income for the families who tend them, year after year.

Join the session liveWatch your trees go into the ground in real time, over video.

Meet the farmersAsk them questions directly. See the land and the seedlings.

Get the recordingSessions are recorded and the video lands on the impact record.

Two extra fieldslive_session_date and impact_video on /v1/track.

Any platform can send a certificate. Almost none can put your customer on a video call with the farmer planting their tree. That's the story that makes impact feel real instead of administrative — use it in your emails, your marketing, and your customer comms.

Omit category and you get standard reforestation trees. Both are verified and tracked identically — food trees simply carry the deeper community story. Ask us about upcoming session dates, or see the impact we've made so far.

What your customer sees after the call

The moment your call succeeds, two things exist: a tracking link and a certificate. Your customer gets both immediately.

But the record isn't static. It fills in as the real-world impact progresses — and both of you can watch it complete. Every stage below is a real field on GET /v1/track.

And through GET /v1/projects/:project_id, the record connects to the full project profile: photographs from the site, the partner organization, country, GPS coordinates, the UN Sustainable Development Goals it advances, and the community work behind it — in English, German, Spanish, French, and Dutch.

Emails: ours, yours, or none

Every impact endpoint takes a notify flag. It decides who tells the customer.

Choose deliberately. The impact email is often the most forwarded and most screenshotted artifact of the whole experience.

Custom email templates

Build the whole experience inside your product

The impact endpoints create impact. The analytics endpoints let you rebuild everything you see on our website inside your platform — your brand, your UI, no redirect out to us.

Not everything needs to be built. If you want impact live before your next sprint, the Shopify app, the Climate Action Badge, and our other no-code integrations run on the same API and the same dashboard.

Pagination is cursor-based — 10 records per page by default, up to 1,000 — with start_date and end_date filters throughout.

Let's make it a partnership

If you'd like to formalize this, we're glad to. A short partnership document — a page or two — outlining that we're building together and what each side brings.

Tell us what would be most valuable on your side and we'll draft something around it. Start the conversation.
