How to connect PDF-app to the Contacts API

A concise guide to wiring the Contacts API with PDF-app for reliable data access.

Steps to securely connect the Contacts API and PDF-app.

This guide covers authentication, endpoint usage, and practical integration patterns to help you read, create, update, and manage contacts and related data from PDF-app via the Contacts API.

Authentication for Contacts API

Access requires a valid API key or OAuth token with the contacts.readonly scope. Store credentials securely and rotate regularly. Use your GHL API name and the app name when configuring connections.

Authentication for PDF-app

PDF-app credentials include a client ID and secret issued for this integration. Use OAuth 2.0 flows or API keys as configured, and scope access to contacts resources.

Endpoint List

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, 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

Top 3 integration patterns between Contacts API and PDF-app

1) Read and synchronize contact data

Trigger: when a contact is created or updated in GHL, fetch the latest data via GET /contacts/:contactId to keep PDF-app in sync.

Actions: pull contact details, update local records, and refresh related tasks, notes, and appointments.

GET /contacts/:contactId

Key fields: contactId, firstName, lastName, email, phone, lastUpdated

Frequently Asked Questions

Do I need to code to integrate the Contacts API with PDF-app?

Access is available through a valid API key or OAuth token with the contacts.readonly scope. You can call endpoints to read contact data, tasks, notes, and appointments. No code can be required if your workflow uses pre built connectors. For advanced needs, you can write custom logic to transform data as it moves between GHL and PDF-app.

You can access contact details, tasks, notes, and appointments. Data types include strings, IDs, timestamps, and nested objects like tasks and notes. Use proper field mappings to align PDF-app records with GHL records for accurate sync.

Authentication uses either API keys or OAuth 2.0 tokens with the appropriate scope. Your app credentials are configured in PDF-app. Access is authorized per token lifetimes and can be refreshed as needed. Always protect credentials and rotate them regularly.

Rate limits depend on your API plan. If you approach the limit, implement exponential backoff and retry logic. Use pagination for large result sets and monitor response headers for quota usage.

Map fields by matching IDs, names, and standard fields like email and phone. Use consistent data types and handle null values gracefully to avoid data integrity issues during sync.

Bulk operations are supported through batch-like calls or scheduled sync. For large migrations, paginate results and process in chunks to prevent timeouts. Always verify data after bulk actions.

The endpoint reference is available in the API docs and in the Endpoint List section above. Use GET endpoints to discover data and POST/PUT/DELETE for modifications as needed.
