How to connect Memberstack to Contacts API

Seamless integration guide to link Contacts API with Memberstack for real-time contact data

Step-by-step connection blueprint for Contacts API and Memberstack

Learn how to securely authenticate, fetch, and push contact data between Memberstack and the Contacts API. This guide covers endpoints, best practices, and no-code workflows to keep data in sync without coding.

Authentication for Contacts API

Your integration uses the Contacts API scope: contacts.readonly to fetch contact data from the GHL platform without write access. Use OAuth tokens securely and rotate them regularly.

Authentication in Memberstack

Keep your Memberstack credentials secure and configure token refresh flows so that API calls remain authenticated without user intervention.

Available Endpoints for Memberstack Integration

– 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 – API Endpoint9: 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

Creative ideas for connecting Contacts API with Memberstack

Idea: Real-time contact sync with field mapping

Set up a near real-time sync so changes in the Contacts API reflect in Memberstack fields instantly. Use mapping rules to align contact properties to Memberstack form fields and CRM fields.

Idea: Automated task lifecycle management

Bridge task creation and completion events between the platforms. Trigger creation of Memberstack tasks when a new task is added in the Contacts API, and sync completion status back to the API.

Idea: Tagging for customer segments

Use tags in the Contacts API to segment customers, and mirror those tags in Memberstack for targeted messaging and automation.

3 steps to connect Contacts API with Memberstack

Step 1: Prepare API credentials

Obtain client ID, client secret, and request access with the scope of contacts.readonly. Store credentials securely in your integration platform.

Step 2: Configure endpoints and data mapping

Map Contacts API fields to Memberstack form and CRM fields. Set up webhook or polling to keep data fresh.

Step 3: Test, validate, and deploy

Run end-to-end tests, verify data sync accuracy, and monitor error logs. Deploy to production once green.

Frequently Asked Questions

What is the Contacts API and what can it do with Memberstack?

The Contacts API exposes endpoints to read contacts, their tasks, notes, and more, enabling you to pull rich contact data into Memberstack. With proper field mapping, you can reflect contact updates back into Memberstack forms and records without manual entry. This setup is ideal for no-code automations and keeping data in sync across platforms. As you configure, ensure you respect the scope (contacts.readonly) for read access and implement secure storage for tokens and credentials to protect sensitive contact information.

Authenticate using OAuth 2.0 tokens with the requested scope of contacts.readonly. Keep tokens secure, rotate them periodically, and use refresh tokens to maintain long-lived sessions without requiring end-user interaction. If your app also needs write access in the future, you may request appropriate scopes and update your integration flow accordingly, while preserving best practices for credential management.

Commonly used endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to pull tasks, and POST /contacts/ to create new contacts. For ongoing synchronization, GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes help keep related data aligned in Memberstack. Additionally, POST /contacts/:contactId/tags is useful for tagging contacts for segmentation and automation.

No-code tools can handle most of the integration, especially for simple syncs and field mappings. For more complex workflows, you may introduce lightweight automation logic or scripts to transform data before it lands in Memberstack. Having a clear mapping plan reduces the need for custom code while preserving flexibility for future changes.

Start with a canonical map: map firstName, lastName, email, and a unique contactId from the API to corresponding Memberstack fields. Extend mappings to tasks, notes, and tags as needed. Use a webhook or periodic polling to synchronize updates and maintain data parity between systems. Test each mapping thoroughly with sample data to confirm accuracy before deploying to production.

Most APIs impose rate limits. Implement exponential backoff with jitter for retries and cache frequently requested data where feasible. Consider batching requests for endpoints that support it and stagger calls to avoid bursts that trigger limits.

Review logs within your integration platform and monitor API responses for errors or latency issues. Some setups provide a dashboard or status endpoint; enable alerting on failure rates to quickly address problems and maintain reliable data flows.
