Use OAuth 2.0 credentials to securely access the Contacts API. Obtain client credentials, set scopes and store tokens securely.
Box authentication uses OAuth 2.0 with your Box app. Configure redirect URLs and scopes to authorize access.

When a contact is created or updated in GHL, sync the data to the Box contact card.
Create or update a Box card, attach relevant tasks and notes.
Example: GET /contacts/:contactId to fetch then POST /contacts/:contactId/tasks to mirror tasks in Box.
Required: contactId, Box card ID, and essential contact fields
Notes and appointments in GHL trigger updates in Box.
Link GHL notes to Box notes and Box appointments to Box calendar items.
Example: GET /contacts/:contactId/notes to fetch notes, then POST to Box notes.
contactId, noteId, Box note IDs
Tag updates or task status changes in GHL trigger Box updates.
Update Box tags and create associated Box tasks as needed.
POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId/completed for sync.
contactId, taskId, Box tag IDs
Build powerful automations without writing code.
Fast data synchronization between Box and GHL contacts.
Reuse endpoint data in Box dashboards and reports.
A quick glossary of terms and processes used when integrating GHL Contacts API with Box.
A person in the GHL Contacts database with identifying information and fields.
A unit of work linked to a contact such as a follow up or reminder.
A text entry linked to a contact providing context or comments.
A specific API URL that exposes data or an action in the GHL API.
Automatically enrich Box contact cards with GHL data.
Create Box tasks from GHL tasks to keep teams aligned.
Attach GHL notes to Box records for richer context.
Obtain OAuth credentials for both Box and the GHL Contacts API.
Define how contact fields map to Box cards, notes and tasks.
Set up triggers and actions to automate data flow between Box and GHL.
You authenticate with OAuth 2.0 using credentials from both Box and the GHL Contacts API. Start by creating a Box OAuth app and a GHL API client, then exchange tokens and store them securely. Use the scopes required for reading and writing contacts, tasks and notes. If you encounter issues, consult the Box developer docs and the GHL API guide for troubleshooting steps.
Yes. You can synchronize tasks, notes and appointments between GHL and Box. Map fields for tasks and notes to the corresponding Box cards and notes, and set up triggers to keep data aligned across systems.
The endpoints include GET for retrieving data such as contacts, tasks, notes and appointments, and POST/PUT/DELETE for creating, updating and removing contacts and associated items. Review the endpoint list to identify which actions fit your workflow.
You can often accomplish many integrations with no code using automation tools and webhooks. For more complex needs, light scripting can be used, but it is not required for standard flows.
Rate limits apply per API. If you reach limits, implement exponential backoff and retry logic, and consider batching requests where possible.
Errors are surfaced via API responses with status codes and messages. Use the error details to adjust requests, retries, and logging. Box and GHL both provide diagnostic data to help troubleshoot.
API credentials are created in your Box and GHL developer portals. Follow the setup guides to obtain client IDs, secrets and scopes, then configure your integration in Zapier or your chosen automation layer.
Due to high volume, we will be upgrading our server soon!
