Authenticate requests using your API credentials with the scope set to contacts.readonly (expand to write as needed). Store credentials securely and rotate keys regularly.
Billetweb authenticates with the Contacts API via API keys and signature verification to ensure secure data transfer.
Key endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, GET /contacts/, GET /contacts/business/:businessId, POST /contacts/:contactId/tags, GET /contacts/:contactId/appointments, and related endpoints for notes.
Trigger: a Billetweb registration creates or updates a contact in GHL
Actions: upsert contact data, attach billet details, apply tags, and set lifecycle stage
Method paths: POST /contacts/ to create, PUT /contacts/:contactId to update
Key fields: email, billetwebId, firstName, lastName
Trigger: Billetweb task events update GHL tasks
Actions: create, update, and close tasks in GHL; link to contact
POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId, status, dueDate
Trigger: Billetweb notes are added or updated
Actions: create notes in GHL, attach to a contact, update notes
POST /contacts/:contactId/notes, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
Key fields: contactId, noteId, content
Automate lead capture from Billetweb events directly into GHL contact records
Keep tasks notes and appointments in sync without custom development
Scale workflows with triggers, actions, and robust data mappings
This section defines the data elements endpoints and processes used to connect Billetweb with the GHL Contacts API
Application Programming Interface the set of rules that lets Billetweb and GHL communicate
A real time notification mechanism that triggers actions when events occur
An event that starts an automation such as a new Billetweb registration
An informational message attached to a contact record
When a Billetweb event registers an attendee, automatically create a GHL contact tag them as attendee and assign an onboarding task
Score leads based on Billetweb interactions and trigger follow ups in GHL
Aggregate Billetweb data into GHL dashboards to monitor campaign performance
Obtain API keys, grant required permissions, and set scope to read write as needed
Map Billetweb fields to corresponding GHL contact fields
Run tests verify data flow monitor logs and roll out
Authentication uses API keys or OAuth depending on Billetweb and GHL settings. Ensure credentials are stored securely and kept confidential. If you see 401 or 403 errors, verify that the tokens are valid and that the scopes include contacts.readonly or write as needed. Also confirm the endpoint paths match the documented version.
Common endpoints for syncing include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks. For notes and appointments use POST /contacts/:contactId/notes and GET /contacts/:contactId/notes, as well as GET /contacts/:contactId/appointments.
Supported data mapping includes core fields like email, firstName, lastName, phone, and billetwebId. You can also map tags notes and tasks to corresponding GHL fields to enrich contact records.
Rate limits depend on your plan. Monitor usage in Billetweb and GHL dashboards and implement exponential backoff. Handle errors by checking status codes, inspecting response bodies, logging payloads, and retrying idempotent requests.
Yes you can test the integration in a sandbox or with a small dataset to avoid impacting live data. Use test endpoints or a controlled environment to simulate Billetweb events and verify data flow.
To reduce duplicates use external IDs such as billetwebId as the primary key when upserting contacts. Implement a deduplication rule and a clear merge strategy based on your data governance.
API keys and setup instructions are available in Billetweb and GHL developer consoles. Generate keys note scopes and redirect URIs. Store credentials securely rotate keys regularly and document mappings for team use.
Due to high volume, we will be upgrading our server soon!
