Acuity Scheduling
Access the Acuity Scheduling API with managed OAuth authentication. Manage appointments, calendars, clients, availability, and more.
Quick Start
# List appointments
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/acuity-scheduling/api/v1/appointments?max=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
Base URL
https://gateway.maton.ai/acuity-scheduling/{native-api-path}
Replace {native-api-path} with the actual Acuity API endpoint path. The gateway proxies requests to acuityscheduling.com and automatically injects your OAuth token.
Authentication
All requests require the Maton API key in the Authorization header:
Authorization: Bearer $MATON_API_KEY
Environment Variable: Set your API key as MATON_API_KEY:
export MATON_API_KEY="YOUR_API_KEY"
Getting Your API Key
- Sign in or create an account at maton.ai
- Go to maton.ai/settings
- Copy your API key
Connection Management
Manage your Acuity Scheduling OAuth connections at https://ctrl.maton.ai.

req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
Specifying Connection
If you have multiple Acuity Scheduling connections, specify which one to use with the Maton-Connection header:
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/acuity-scheduling/api/v1/appointments')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))

Pagination
Acuity Scheduling uses the max parameter to limit results. Use minDate and maxDate to paginate through date ranges:
# First page
GET /acuity-scheduling/api/v1/appointments?max=100&minDate=2026-01-01&maxDate=2026-01-31
# Next page
GET /acuity-scheduling/api/v1/appointments?max=100&minDate=2026-02-01&maxDate=2026-02-28
Code Examples
JavaScript
const response = await fetch(
'https://gateway.maton.ai/acuity-scheduling/api/v1/appointments?max=10',
{
headers: {
'Authorization': `Bearer ${process.env.MATON_API_KEY}`
}
}
);
const appointments = await response.json();
Python
import os
import requests
response = requests.get(
'https://gateway.maton.ai/acuity-scheduling/api/v1/appointments',
headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
params={'max': 10}
)
appointments = response.json()
Notes
- Datetime values must be parseable by PHP's
strtotime()function - Timezones use IANA format (e.g., "America/New_York", "America/Los_Angeles")
- Client update/delete requires clients to have existing appointments
- Rescheduling requires the new datetime to be an available time slot
- Use
excludeForms=truefor faster appointment list responses - IMPORTANT: When using curl commands, use
curl -gwhen URLs contain brackets to disable glob parsing - IMPORTANT: When piping curl output to
jqor other commands, environment variables like$MATON_API_KEYmay not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.
Error Handling
| Status | Meaning |
|---|---|
| 400 | Invalid request (e.g., time not available, client not found) |
| 401 | Invalid or missing Maton API key |
| 404 | Resource not found |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Acuity API |
Troubleshooting: API Key Issues
- Check that the
MATON_API_KEYenvironment variable is set:
echo $MATON_API_KEY
- Verify the API key is valid by listing connections:
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
Troubleshooting: Invalid App Name
- Ensure your URL path starts with
acuity-scheduling. For example:
- Correct:
https://gateway.maton.ai/acuity-scheduling/api/v1/appointments - Incorrect:
https://gateway.maton.ai/api/v1/appointments
