Using the API and creating API keys

Want to connect TinyCourier to your own website, app, or tools? The API lets you add subscribers, manage your list, and more, automatically. This page gets you started. (If you’re not a developer, you can safely skip it.)

What you can do with the API

• Add and update subscribers from your own site or app.
• Manage tags, fields, and segments.
• Trigger and track sends.
• Receive webhooks, real-time notifications when things happen (a new subscriber, a bounce, etc.).

Creating an API key

An API key is like a password that lets another tool act on your account.

1. Go to API keys → New key.
2. Give it a name you’ll recognize (e.g. “Website signup”).
3. Choose its permissions (scopes), only grant what that tool actually needs.
4. Copy the key and store it somewhere safe.

Important: the key is shown once, at creation. Copy it right away. If you lose it, just delete it and make a new one.

Keep your keys safe

• Never put a key in public code, a webpage, or a shared doc.
• Give each tool its own key, so you can revoke one without affecting the others.
• Use the narrowest scopes that get the job done. A form that only adds subscribers doesn’t need permission to delete them.
• Delete keys you no longer use. You can see when each key was last used on the API keys page.

The full reference

Every endpoint, with examples, lives in the interactive API docs:

👉 api.tinycourier.com/docs (also linked from inside your account)

There you’ll find request formats, response shapes, and how to authenticate using your key.

No-code option

Not ready to write code? Many tools (like Zapier-style automation platforms) can talk to the API for you using your key, no programming required.
