Access to the GHL Contacts API is controlled by an API key with the required scope (for example, contacts.readonly or full access). Treat keys like precious assets—store them securely, rotate them periodically, and never expose them in client code.
Connect Landingi to GHL using OAuth 2.0 or a dedicated API credential set configured in the Landingi developer console. Align scopes to read and write contact data and restrict access to only what’s needed.
– 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
Trigger: A new Landingi form submission starts a sync to GHL to create or update a contact.
Actions: POST /contacts/ to create, or PUT /contacts/:contactId to update, mapping fields such as email, name, phone, and company from Landingi form submissions.
Endpoint usage: POST /contacts/ to create a contact; PUT /contacts/:contactId to update an existing one.
Key fields: email (used as a unique identifier), firstName, lastName, phone, company.
Trigger: Landingi events trigger creation or update of tasks and notes in GHL when a lead requires follow-up.
Actions: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/notes
Endpoint usage: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/notes
Key fields: contactId, taskId, status, dueDate, noteId
Trigger: Landingi interactions trigger notes or appointment entries in GHL.
Actions: POST /contacts/:contactId/notes; GET /contacts/:contactId/appointments
Endpoint usage: POST /contacts/:contactId/notes; GET /contacts/:contactId/appointments
Key fields: contactId, noteId, appointmentId
No-code setup lets marketing teams automate lead capture to CRM without writing a line of code.
Intuitive visual mapping, triggers, and actions enable rapid automation iterations.
Scale across campaigns and teams while maintaining data accuracy in GHL.
Core elements include API endpoints, authentication methods, triggers, actions, and field mappings—described below.
A defined interface that allows software to request and exchange data.
A URL or route in an API that performs a specific operation or returns data.
The process of proving identity and granting access to an API, typically via API keys or OAuth tokens.
A typed data attribute that describes a contact record, such as email, firstName, lastName.
Automatically create or update GHL contacts whenever Landingi form submissions occur.
Generate follow-up tasks in GHL when a new lead enters Landingi.
Attach contextual notes to contacts based on Landingi interactions.
Create and secure API credentials in GHL and configure Landingi to use them.
Select endpoints and map Landingi fields to GHL contact fields.
Test data flows, validate mapping, and deploy the integration.
The GHL Contacts API lets apps read, create, update, and delete contact data programmatically, which is essential for keeping Landingi form submissions in sync with your CRM. By hitting the API, you ensure every new lead from Landingi becomes a properly populated contact in GHL with consistent field values. This foundation also enables you to attach follow-up tasks, notes, and appointments as part of a unified lead journey. With this integration, you gain reliable bidirectional data flow, meaning Landingi can push new information to GHL and pull back status or details as your campaigns evolve, all without manual data entry.
No extensive coding is required. You can leverage no-code automation tools or prebuilt templates to wire Landingi forms to GHL, mapping fields and selecting triggers with a visual editor. If you need custom logic, lightweight scripting or a templated flow can handle it without creating a full backend. Always start with a safe test environment to validate mappings before going live.
Begin with retrieving a contact using GET /contacts/:contactId to understand the shape of data you’ll work with. Then try creating a contact with POST /contacts/ for new leads. Once the basics are working, expand to fetching related resources like tasks, notes, or appointments to build richer automations and data synchronization.
Authentication is done with API keys or OAuth tokens. Store credentials securely in your admin console, rotate keys regularly, and avoid exposing tokens in client-side code. Use the least-privilege scope required for your integration to minimize risk.
Yes. The API includes endpoints for tasks and notes, enabling you to create and update follow-ups and attach contextual notes to contacts. You can also schedule and fetch appointments to keep timelines aligned across your teams.
Field mapping is performed by pairing Landingi form fields with GHL contact fields. Validation checks typically include required fields (like email), data formats, and uniqueness constraints to prevent duplicate contacts. Regularly review your mappings as your forms and CRM fields evolve.
API limits and pricing vary by plan and usage. Check the GHL documentation for current rate limits and quotas, and consider contacting support if you anticipate higher throughput or more complex automation requirements.
Due to high volume, we will be upgrading our server soon!
