Use OAuth 2.0 and API keys for secure access to the Contacts API. Ensure the scope is set to contacts.readonly (and other required scopes) and store tokens securely within the Zapier App Connector.
Authenticate the connector via OAuth 2.0 in your Zapier account. Keep tokens secure, refresh as needed, and apply least-privilege access for your workflows.
Available endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId, contacts.write, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags

Automate repetitive data entry without writing code
Use ready-made triggers and actions to speed up workflows
Centralize contact data across apps for better segmentation
Understand endpoints, triggers, actions, auth, and data mapping you’ll use in your connectors.
A specific URL path in the API that performs a defined operation, such as retrieving a contact or updating a record.
The authorization framework used to securely access APIs, often via access tokens.
An event that starts a Zap or workflow, such as a new contact creation.
An operation performed in response to a trigger, such as creating a task or updating a record.
When a new contact is created, tag them in your CRM and attach a lifecycle stage automatically.
Route leads to the correct owner and notify via Slack or email to accelerate follow-ups.
After an appointment, automatically create a follow-up task and send calendar invites.
Log into Zapier, add the Contacts API as a connection using OAuth 2.0 credentials.
Choose endpoints like /contacts and /contacts/:contactId and map fields to your apps.
Create a Zap to trigger on new contacts and test the end-to-end flow.
No coding is required. The Zapier App Connector provides a no-code interface to connect the Contacts API, configure triggers, and set up actions across apps. If you need more complex logic, you can add filters, paths, and multi-step Zaps without writing code. Additionally, the docs include step-by-step setup guides and example workflows to get you started quickly. For advanced scenarios, you can leverage conditional logic and data transformations within Zapier to tailor the flow to your business process.
Supported authentication methods include OAuth 2.0 for secure token-based access and API keys where appropriate. The Contacts API usage in the Zapier App Connector relies on OAuth 2.0 scopes (such as contacts.readonly) to control access. Tokens should be stored securely within Zapier and refreshed automatically as needed. Always follow the principle of least privilege for each connection.
Key endpoints include: GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to retrieve associated items, POST /contacts/ to create a contact, PUT /contacts/:contactId to update, DELETE /contacts/:contactId to remove, and endpoints for tasks, notes, and appointments as listed in the endpoint guide. You can also access bulk listings with GET /contacts/ and related business-scoped endpoints like GET /contacts/business/:businessId.
Yes. Within Zapier you can map fields from Contacts API to any connected app using the built-in field mapping UI. This requires no custom code and supports common fields such as name, email, phone, and custom fields. You can also use transforms to format data before it’s sent to the target app.
Use Zapier’s test feature to simulate the trigger with sample data. Run a test from the trigger step, verify that the action steps receive the expected payload, and review any errors in the task history. It’s best to test with real-world data representative of your workflow and iterate until the end-to-end flow works reliably.
Data synchronized includes contact records, associated tasks, notes, and appointments, depending on the endpoints you map in your Zap. You can control what fields are exchanged and how often the data syncs. Mapping rules determine how source fields populate target fields across connected apps.
API rate limits and error handling guidance are documented in the integration docs. When limits are approached, implement exponential backoff and retry logic within your Zaps. For errors, review the error messages in Zapier task history and adjust mappings or scopes as needed.
Due to high volume, we will be upgrading our server soon!
