Obtain API credentials from your GHL account and configure authentication in Zapier to access the Contacts API. The provided Scope is contacts.readonly for most read operations; write access requires appropriate permissions and enabling endpoints.
In Zapier, set up authentication by selecting API Key or OAuth, then paste your GHL credentials. This connection ensures requests to the SOLAPI endpoints succeed and keeps data flowing between GHL and your connected apps.
– 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 contact is created in GHL; automatically create a follow-up task in your connected app via Zapier.
Actions: Use GET /contacts/:contactId to fetch data, POST /contacts/ to create, and POST /contacts/:contactId/tasks to assign follow-up tasks.
Example method paths: GET /contacts/:contactId, POST /contacts/, POST /contacts/:contactId/tasks
Key fields: contactId, taskId, businessId
Trigger: Notes or appointments are added/updated in GHL and should be reflected in connected apps.
Actions: Create or update notes and appointments using endpoints like GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments; use POST/PUT as needed.
Sample paths: GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
Key fields: contactId, id, appointmentId
Trigger: Apply or adjust tags on a contact to route workflows across apps.
Actions: Use POST /contacts/:contactId/tags to assign or update tags and drive downstream automations.
Method path: POST /contacts/:contactId/tags
Key fields: contactId, tagIds
Build powerful automations without writing code, connecting GHL to Zapier with simple triggers and actions.
Achieve real-time data synchronization between GHL and your downstream apps for up-to-date information and faster workflows.
Scale automations across teams with templates and reusable zap workflows.
Key elements include API, endpoints, triggers, actions, authentication, and data fields. This glossary explains how these pieces come together to enable SOLAPI integrations with Zapier App Connector.
An API (Application Programming Interface) is a set of rules that lets software components communicate with the GHL Contacts API to access contacts, notes, tasks, and more.
An endpoint is a specific URL path in the API that performs a function, such as retrieving a contact or creating a task.
A webhook is a way for apps to receive real-time updates by sending a message when something happens in GHL or connected apps.
The process of verifying identities to allow a request to access data from the GHL API.
Set up a Zap to scan for duplicate contacts and flag or merge them in GHL to maintain data cleanliness.
Automatically schedule follow-ups when a new lead enters the system, ensuring timely engagement.
Route contacts to different apps based on tags for segmented workflows and targeted outreach.
From GHL, generate or retrieve an API key for the Contacts API.
In Zapier, add authentication using the API key and set the scope to contacts.readonly.
Create a test Zap that pulls a contact and creates a follow-up task to verify end-to-end connectivity.
Read-only access typically covers retrieving contact data, tasks, notes, and appointments. This protects data while enabling automation. If your workflow requires updates, ensure your API key has write permissions enabled by your GHL administrator and that you are using endpoints that support changes.
Yes, write-capable endpoints exist (such as POST /contacts/, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags) when your credentials include the appropriate permissions. Always verify scope and rate limits in your GHL account and API docs before enabling write actions.
Onboarding typically begins with GET /contacts/ to fetch a list of new leads, then POST /contacts/ to create or PUT /contacts/:contactId to update. For a starter flow, consider syncing new contacts to a follow-up task and tagging for segmentation.
Rate limits depend on your GHL plan and API usage. Plan for bursts during peak automation and implement retries with exponential backoff. If you hit limits, stagger jobs or queue tasks in Zapier to maintain reliability.
API documentation for SOLAPI is available in your GHL developer portal and the SOLAPI reference guides. Use the endpoint list above as a quick start, and consult official docs for authentication and data schemas.
Due to high volume, we will be upgrading our server soon!
