Scheduler Zero
REST API

Quickstart

Create an API key and make your first Scheduler Zero REST request.

1. Create an API key

Open Settings → API Keys, create a key, and select only the permission scopes your integration needs. Copy the key when it is shown.

2. Store the key

export SCHEDULER_ZERO_API_KEY="sz_your_api_key_here"

Use a secret manager in production. Do not commit API keys to a repository or include them in client-side browser code.

3. Verify the credential

curl https://api.schedulerzero.com/v1/me \
  -H "x-api-key: $SCHEDULER_ZERO_API_KEY"

4. Call an operation

curl https://api.schedulerzero.com/v1/campaigns \
  -H "x-api-key: $SCHEDULER_ZERO_API_KEY"

See the API reference for request parameters, bodies, responses, and required scopes.
