To connect, obtain credentials from your Contacts API account and grant Zapier access with the required scope (readonly by default).
Zapier will prompt you to authorize access to your Contacts API data. Approve the requested scopes to proceed, then choose which operations Zapier can perform.

To connect, you’ll need credentials from your Contacts API account—usually an API key or OAuth token. Ensure your account has the appropriate scope (readonly or write) and that you’ve enabled access for Zapier. Store these credentials securely in your Zapier account or a secret store. In Zapier, start by selecting the Contacts API as the app, authenticate using the credentials, then choose a trigger and action to build your automation.
The endpoints available include both read and write operations such as GET /contacts/:contactId and POST /contacts/. Use GET when you need to fetch data, and POST/PUT when updating. Review the endpoint list in this guide to plan your workflow. Keep in mind permissions and scopes as you map fields between apps.
Rate limits vary by account and plan; see the documentation for specifics. Plan accordingly and avoid bursts that could trigger throttling. For resilience, implement retries with backoff and monitor usage.
Yes, Zapier can write data to the Contacts API using endpoints like POST /contacts/ or PUT /contacts/:contactId. Ensure the required scopes are granted and map fields carefully to avoid duplicates. Test changes in a sandbox before going live.
Store API keys securely using Zapier Secrets or a secure vault; never embed keys in page content. Rotate credentials regularly and monitor access. Use auditing and alerts to detect unusual activity.
Common errors include authentication failures, missing required fields, and rate limit exceeded. Use the error details to adjust requests, retry with backoff, and test in a sandbox. Consider enabling webhooks and logging for visibility.
The endpoint list is in the Endpoints section of this guide and covers read and write operations for Contacts. It explains when to use each endpoint and provides practical examples for Zapier automations.
