Obtain OAuth 2.0 tokens with the contacts.readonly scope to read contact data and use refresh tokens for long running automations.
Configure an app credential in NiftyImages to authorize requests to the GHL Contacts API, then secure the token and set the required scope (contacts.readonly).
GET /contacts/:contactId – Retrieve a single contact by ID GET /contacts/:contactId/tasks – List tasks for a contact GET /contacts/:contactId/tasks/:taskId – Get a specific task GET /contacts/:contactId/notes – List notes for a contact GET /contacts/:contactId/notes/:id – Get a note GET /contacts/:contactId/appointments – Get appointments for a contact GET /contacts/ – List all contacts GET /contacts/business/:businessId – List contacts by business POST /contacts/ – Create a new contact PUT /contacts/:contactId – Update a contact DELETE /contacts/:contactId – Delete a contact POST /contacts/:contactId/tasks – Create a new task for a contact PUT /contacts/:contactId/tasks/:taskId – Update a task PUT /contacts/:contactId/tasks/:taskId/completed – Mark a task as completed DELETE /contacts/:contactId/tasks/:taskId – Delete a task POST /contacts/:contactId/tags – Add tags to a contact
Trigger when a contact is created or updated in NiftyImages to sync data back to GHL
Update contact fields in GHL; create related tasks if needed
Use POST /contacts/ to create contacts and PUT /contacts/:contactId to update; keep identifiers aligned
Required: contactId, email, name
Trigger when a new campaign event occurs in NiftyImages that requires follow-up in GHL
Create/update tasks in GHL; set due dates and reminders
POST /contacts/:contactId/tasks
Key: taskId, contactId, status, dueDate
Trigger when notes are added in NiftyImages
Sync notes to GHL and attach to the contact timeline
GET /contacts/:contactId/notes and POST /contacts/:contactId/notes
NoteId, contactId, content
Automate data flow without writing code by using Zapier-style connectors
Keep contact data and tasks in sync across platforms
Accelerate campaigns with unified data and insights
This glossary covers APIs, endpoints, authentication, payloads, and how they work together in the NiftyImages-to-GHL flow.
Application Programming Interface: a defined set of calls that let apps talk to each other.
URIs combined with HTTP methods that perform operations like read, create, update, or delete data.
Authorization framework to grant limited access tokens for API calls.
A callback that notifies your app when an event occurs in another service.
Capture signup data from NiftyImages campaigns and create or update contacts in GHL; trigger welcome automation.
Create tasks in GHL when a contact engages with an image, prompting follow-up.
Attach notes to contacts after image previews to prep for calls.
In NiftyImages, create an API key and grant access to the Contacts scope.
Enable the endpoints you will use: GET /contacts, POST /contacts, and related task/note calls.
Run tests with sample contact data and monitor error logs before going live.
The Contacts API lets you read contact data such as name, email, phone, and custom fields, and read related resources like tasks and notes. Read access enables powerful automation and reporting across NiftyImages campaigns. Note that write operations require appropriate permissions beyond the readonly scope. If you need to update data, ensure you have the necessary write access granted by your GHL app configuration.
No-code integration is possible using connectors like Zapier, Integromat, or native app connectors. You can map NiftyImages events to GHL actions without custom code. If you choose to code, use the REST endpoints described above to call create, read, update, or delete operations.
Essential endpoints for basic workflows include GET /contacts/:contactId to fetch a contact, POST /contacts/ to create, PUT /contacts/:contactId to update, and GET /contacts/:contactId/tasks for related tasks. For notes, use GET /contacts/:contactId/notes and POST /contacts/:contactId/notes to attach new notes.
Authentication is typically via OAuth 2.0 tokens. Obtain an access token with the appropriate scope (e.g., contacts.readonly for reading data). Store tokens securely and refresh when needed. Include the token in the Authorization header of API requests.
Yes. If your app has write permissions (e.g., contacts.write), you can update contact records using PUT, create tasks with POST, and attach notes with POST. Always validate responses and handle conflicts or validation errors gracefully.
Handle errors by inspecting HTTP status codes and API error messages. Implement retries with exponential backoff for transient failures, log error details, and notify your team if persistent failures occur.
Endpoint examples and docs are available in the API reference and developer portal. Start with the endpoint list shown above to understand the basic operations, then explore detailed docs for each resource and payload structure.
Due to high volume, we will be upgrading our server soon!
