Use OAuth 2.0 to obtain a token that grants SaaS API access to GHL resources. Register the SaaS app, request the required scopes, and securely store access tokens.
Configure OAuth on the SaaS side to request the necessary scopes and to handle redirects and token refreshing for ongoing access to GHL.
GET /oauth/installedLocations; POST /oauth/locationToken; saas/location.write; PUT /update-saas-subscription/:locationId; POST /enable-saas/:locationId. Additional endpoints may be used for future features.
Trigger: a SaaS location is first linked from the GHL app to SaaS API.
Actions: fetch installedLocations, request a locationToken, and save the mapping in SaaS for future calls.
GET /oauth/installedLocations, POST /oauth/locationToken
Key fields: locationId, clientId, scopes, accessToken
Trigger: new SaaS location is created in your app and needs provisioning in GHL.
Actions: call saas/location.write to provision, then update subscription as needed.
PUT /update-saas-subscription/:locationId, POST /enable-saas/:locationId
Key fields: locationId, subscriptionStatus, locationName
Trigger: SaaS events map to GHL triggers via webhooks.
Actions: subscribe to events, route payloads to GHL automation, and log results.
See endpoint list for event subscription and token exchange endpoints
Key fields: eventId, eventType, payload
Prebuilt triggers and actions let you automate common workflows without writing code.
OAuth ready endpoints enable quick setup and secure token management.
Extend with webhooks and data mapping for custom automation and reporting.
This glossary defines the core terms used in the SaaS API to GHL integration, including OAuth scopes, endpoints, location tokens, and data mapping.
OAuth is an open standard for access delegation that lets SaaS API request access to GHL resources without handling user credentials.
A URL path that exposes a specific function in GHL for SaaS API calls.
Scopes define the level of access the SaaS API is requesting from GHL resources.
A token tied to a specific SaaS location used to authenticate requests to GHL resources.
Use installedLocations to auto provision new accounts and trigger a welcome workflow in GHL.
Collect SaaS events and feed them into GHL dashboards for product and marketing insights.
Trigger campaigns and automations based on subscription status or feature flags.
Collect client ID, client secret, and required OAuth scopes from the SaaS API app settings.
Register the redirect URI in GHL and configure the correct scopes for location read and write access.
Run test calls such as GET /oauth/installedLocations and POST /oauth/locationToken to verify tokens and mappings.
To connect, register your SaaS app in the SaaS API portal, request the OAuth scopes needed for location read and write, and store client credentials securely. Then configure the redirect URI in GHL and initiate the authorization flow to obtain an access token. Finally, map the locationId and tokens in SaaS so future calls are authenticated. Follow best practices such as rotating tokens and using secure storage to protect credentials.
During setup you will interact with endpoints like GET /oauth/installedLocations to discover current locations and POST /oauth/locationToken to exchange authorization codes for tokens. You may also use saas/location.write to provision a new location and endpoints to update subscriptions. Review the API docs for the exact parameter names and response formats.
No heavy coding is required thanks to prebuilt triggers, actions, and webhooks. You can assemble a working integration with conditional logic and simple mappings in the GHL automation builder. If you need custom logic, small scripts or middleware can extend the flow.
Security is handled with OAuth tokens, short-lived access tokens, and secure storage of client secrets. Use least privilege scopes and rotate tokens periodically. Ensure redirect URIs are whitelisted and monitor token usage with logs.
Test the connection in a sandbox environment by triggering a new location creation, initiating token requests, and validating that API calls succeed with the stored tokens. Use sample payloads to verify field mappings and error handling.
Yes. You can map fields between SaaS and GHL using transformation rules in your automation, or via a lightweight middleware layer. Define how location fields, subscriptions, and event payloads align with GHL data structures.
Tokens are issued by the SaaS API OAuth flow and can be refreshed using the refresh token. Store tokens securely and monitor expiration. The frequency of rotation depends on your security policy and the token lifespans configured by SaaS API.
Due to high volume, we will be upgrading our server soon!
