Access to the Contacts API requires a secure token with the appropriate scope (contacts.readonly). Use OAuth 2.0 or a issued API key from your GHL developer console to authorize requests.
In Little Green Light, generate an API key or configure OAuth to grant permissions for reading and writing contact data. Store credentials securely and rotate them regularly.

Eliminate manual data entry with automated, rules-based sync between systems.
Improve data accuracy and reduce duplicates through centralized field mappings.
Faster go-live with templates, visual builders, and low-code workflow automation.
Key data elements and processes used in the integration include contacts, tasks, notes, field mappings between GHL and Little Green Light, authentication, error handling, and retries.
A person record in your CRM that stores identity details and communication history.
A to-do item associated with a contact, used to track actions and next steps.
A text entry linked to a contact documenting information, updates, or notes from interactions.
A specific URL path that performs an action when called with proper authentication.
Pull basic demographic data from Little Green Light into GHL to enrich contact records without manual entry.
Create tasks in GHL when important events occur in Little Green Light, such as new member signups or renewals.
Sync notes to surface context for sales and support teams and trigger follow-ups.
Grant permissions to both apps, set scopes (read/write as needed), and obtain API tokens or OAuth credentials.
Define field mappings between Little Green Light and the Contacts API so data lands in the right places.
Run test records, verify data fidelity, and enable automation across teams.
No coding is required. Use the visual builders and pre-built templates to configure authentication, mappings, and endpoints. If you prefer, you can export a starter workflow as a JSON template and adjust it to your data model. This makes it easy to get started quickly without developer help.
You can sync core contact fields (name, email, phone), plus notes and tasks. More advanced mappings can bring in custom fields from Little Green Light and map them to GHL custom fields.
All data in transit is encrypted with TLS. Secrets are stored securely and rotated on a schedule. Follow your organization’s security guidelines for API keys and tokens.
Yes. You can enable or disable specific endpoints and adjust field mappings to limit data and control which records sync.
The integration includes retry logic with exponential backoff. Errors are surfaced in a centralized dashboard and can trigger alerts or notifications.
Yes, the integration can support one-way or two-way sync depending on your mappings and permissions configured in both apps.
Most setups go live in under 30 minutes with templates, though complex mappings and custom fields may take longer to test and finalize.
Due to high volume, we will be upgrading our server soon!
