Access the Contacts API using OAuth 2.0 with the required scope: contacts.readonly.
Authorize your youengage app to call the Contacts API via the standard OAuth flow and the necessary scope (contacts.readonly).
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 when a contact is updated in GHL to push changes to youengage.
Actions include creating or updating contacts, logging tasks, and attaching notes.
Typical usage: GET /contacts/:contactId to fetch a contact; POST /contacts/ to create; PUT /contacts/:contactId to update.
Key fields: contactId, email, name, phone
Trigger when tasks are due or updated to reflect status in youengage.
Create/update tasks, mark complete, link to contacts.
POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, contactId, status, dueDate
Trigger when notes are added or updated for a contact.
Create notes, fetch notes, and attach to the related contact.
GET /contacts/:contactId/notes, POST /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
Key fields: noteId, id, contactId
Fast setup with API-driven workflows in your no-code stack.
No-code automation between GHL Contacts API and youengage using webhooks and triggers.
Scalable data synchronization across apps without custom coding.
This glossary defines core terms and shows how endpoints map to data flows between GHL and youengage.
The GHL API is the authenticated interface you use to access GHL data and perform operations on contacts, tasks, notes, and more.
A specific API URL and HTTP method used to perform a defined action against the GHL platform.
A callback URL that GHL or your app can use to notify events like contact updates in real time.
The standard authorization framework used to obtain access tokens for calling the GHL API securely.
Build a real-time view of contact updates and tasks between GHL and youengage to drive campaigns.
Create templated flows that sync new contacts to youengage lists and trigger actions.
Outline resilient retry logic and clear error messages for API failures.
Create an OAuth client in your GHL account, note client_id and client_secret, and set redirect URIs for youengage.
Run the OAuth authorization flow from youengage to grant access to Contacts API with the required scopes.
Test endpoints in a staging environment, confirm data mappings, then switch to production.
You can access contact records, tasks, notes, and appointments, all tied to unique contact identifiers. The API also supports filtering and pagination to help you fetch exactly what you need. In practice, most integrations read-only data with the contacts.readonly scope, but write operations are available when you request the appropriate permissions.
Security is built in with OAuth 2.0, token rotation, and scoped access. Ensure credentials are stored securely and implement retries with backoff to handle transient failures. Compliance considerations include protecting PII and following your data governance rules.
Yes. A developer can help you implement connections, but basic connections can be set up with guided steps and SDKs. For most teams, a lightweight integration engineer is sufficient.
The primary scope used is contacts.readonly for read operations; write access requires additional permission. If your app needs to modify data, apply for write scope and ensure endpoints used match.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. Deleting is available via DELETE /contacts/:contactId, with proper safeguards.
Most APIs implement rate limits. If you hit a limit, retry after the recommended backoff period and consider batching requests or caching results where practical.
Common errors include invalid tokens, missing scopes, and malformed requests. Use the error codes in the response to adjust and retry with exponential backoff.
Due to high volume, we will be upgrading our server soon!
