Learn how to securely authenticate with the Contacts API via Zapier App Connector using API keys or OAuth.
Set up credentials in the Zapier App Connector to access the Contacts API securely.
Below is a concise list of the core endpoints used in Base64 Encoder-Decoder workflows.
Trigger example: fetch a contact’s details when a Zap runs.
Actions include retrieving tasks and notes for the contact, or updating the contact.
Endpoint path: GET /contacts/:contactId
Key fields: contactId, email, name
Trigger: pull all tasks for a given contact
Actions: create, update, or delete tasks
Endpoint path: GET /contacts/:contactId/tasks
Key fields: taskId, status, dueDate
Trigger: fetch a specific task by ID
Actions: update task details, mark complete or delete
Endpoint path: GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Automate data flow between Contacts and your apps with no code.
Leverage ready-made triggers and actions to speed up workflows.
Securely manage credentials and access with the App Connector.
Key concepts and processes to connect and work with the Contacts API via the Zapier App Connector.
API stands for Application Programming Interface, a set of rules that lets apps communicate.
OAuth 2.0 is a secure standard for authorizing access to APIs without sharing passwords.
An API endpoint is a URL where a specific function can be accessed.
Base64 encodes binary data as ASCII text to safely transfer over text-based protocols.
Automatically tag and route new contacts to the right workflow using base64 encoded payloads.
Decode incoming payloads to extract fields and trigger downstream steps.
Keep a base64 encoded log of events for auditing inside your app.
In Zapier, authorize the Contacts API and store credentials securely in the App Connector.
Configure triggers like on new or updated contact and actions like create task or add notes.
Run tests, verify the Base64 encoder/decoder flows, and deploy to production.
Base64 encoding converts binary data into ASCII text, enabling safe transmission over text-based protocols. It is useful for embedding binary or special characters in API payloads. In this guide we show how the Base64 Encoder-Decoder in the Zapier App Connector can be used with the Contacts API to handle payloads that include binary or non ASCII data. This helps keep data integrity across transfers. The encoder and decoder blocks can be layered into your Zap to ensure payloads are properly encoded for outbound requests and decoded on inbound responses.
To authenticate, create an API key or OAuth flow in the Contacts API and store credentials securely in the App Connector. Zapier will pass tokens or keys with each request. Tokens can be refreshed as needed without exposing credentials in your workflow.
This guide covers a core set of endpoints such as GET /contacts/:contactId and related resources like tasks and notes. You can also use POST, PUT, or DELETE to manage contacts, tasks, and other related data as your workflow requires.
Yes. You can decode data in the Zapier App Connector to extract fields from a Base64 payload and feed those values into subsequent steps. Use the decoder node to reveal fields like contactId, taskId, or notes content.
The integration is designed to be no-code friendly within Zapier App Connector, featuring visual triggers and actions. Some advanced flows may benefit from simple expressions, but no heavy coding is required.
Test endpoints using Zapier’s built in test functionality and the App Connector’s test mode. Validate encoded payloads, decoding results, and error handling before going live.
Learn more about Base64 encoding and API workflows in the official docs. Review endpoint references and sample Zaps to understand how payloads flow through the Contacts API with the App Connector.
Due to high volume, we will be upgrading our server soon!
