Automate workflows without writing code.
Centralize contact data from multiple sources in one workflow.
Test, iterate, and deploy quickly with live data.
This glossary covers endpoints, triggers, actions, authentication, and data fields you’ll encounter when integrating Contacts API with Zapier.
A specific URL path that accesses a resource in the API.
An event in your app that starts an automated workflow in Zapier.
An operation performed in response to a trigger, such as creating or updating a contact.
The method used to securely verify your identity and authorize API requests.
When a new contact is created in the source system, automatically generate a starter task in the related system via the API.
Push contact notes to a central knowledge base or note-taking app for quick reference.
Update contact records automatically when form data is submitted via Zapier.
In Zapier, add a new connection using Contacts API credentials.
Select triggers like contact update and map actions such as fetch, create, or tag operations.
Run tests with live data and enable automation.
Yes—authentication is handled via the Zapier connection for Contacts API, typically using OAuth or an API key. This connection securely authorizes each API call from Zapier. Once connected, you can access resources through the standard endpoints described in the reference. In all cases, keep your credentials safe and rotate them per your security policy. The Zapier App Connector handles token renewal and secure storage of credentials, so you can focus on building your automations without managing the auth boilerplate manually.
The available endpoints cover contacts, tasks, notes, and basic management operations for business contexts. Examples include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId. There are also endpoints for notes, appointments, and tagging contacts to support richer data workflows. For a complete list, refer to the endpoint overview in the integration documentation.
Yes. You can update a contact or a task by using PUT requests with the appropriate IDs. For example, PUT /contacts/:contactId updates a contact, and PUT /contacts/:contactId/tasks/:taskId updates a task. Ensure you include all required fields and that the user has write permissions on the resource. Validation errors will return actionable messages to help you fix the request payload.
Rate limits apply per your Zapier and API plan. If you hit limits, you may receive a throttling response. Plan-aware usage helps avoid interruptions by staggering calls or batching requests when possible. If you anticipate high throughput, consider upgrading or implementing efficient triggers and polling intervals to stay within your quota.
In Zapier, create a test trigger and run a test action using sample data. Validate that the data maps correctly to your destination apps and that the API responses are as expected. Use the built-in test features to simulate real-world flows before deploying to production. Review any error messages and adjust field mappings or authentication settings as needed.
No-code automation is supported via Zapier App Connector, so you can build end-to-end flows with triggers and actions without writing code. You can also add filters, paths, and multi-step sequences to handle complex logic. Advanced users can incorporate custom logic via built-in tools or external services if needed, but most scenarios can be achieved with point-and-click configuration.
Endpoint documentation and reference materials are provided within the integration docs and API reference. They include endpoint names, required parameters, authentication details, and example requests/responses. If you need more, you can access developer resources or contact support for deeper guidance and sample workflows.
Due to high volume, we will be upgrading our server soon!
