Authenticate requests using your API credentials. The Contacts API supports OAuth 2.0 or API keys and operates under the scope ‘contacts.readonly’ to protect sensitive data.
Grant Launch27 permission to read your Contacts data via an OAuth 2.0 flow. Ensure the scope matches ‘contacts.readonly’ and securely store the resulting access token.

No-code data integrations let you sync contacts and activities without writing custom code.
Automated workflows save time and reduce errors by moving data between systems without manual exports.
Centralized customer data within Launch27 enables faster outreach and smarter segmentation.
This glossary defines core elements and processes used when connecting the GHL Contacts API with Launch27, including contacts, endpoints, notes, tasks, and tags.
A contact is a person stored in your CRM with identifying details like name, email, and phone.
A task is an activity associated with a contact, used to track follow-ups and deadlines.
A note is a freeform piece of information attached to a contact for context.
A tag is a label used to categorize contacts for segmentation and filtering.
Automatically create a new contact, assign initial tasks, and attach an onboarding note when a lead signs up.
Use tags to segment audiences in Launch27 and trigger targeted messages based on activity.
Create end-to-end flows that update contact records and log progress through notes and tasks.
Create an API client in GHL, obtain client credentials, and authorize Launch27 to access your Contacts data.
Select the endpoints you need (contacts, notes, tasks) and map fields to Launch27.
Test requests in a sandbox, monitor logs, and move to production when ready.
Access is controlled by OAuth scopes or API keys. For read-only access to contacts, the ‘contacts.readonly’ scope is required. Ensure your app only requests the permissions it needs.\nKeep credentials secure, rotate keys regularly, and apply least-privilege access to minimize risk.
Authenticate requests using OAuth 2.0 tokens or API keys as configured for your app. Include the access token in the Authorization header (Bearer
Yes, many write endpoints are available when your app has the appropriate permissions (for example, PUT /contacts/:contactId and POST /contacts/:contactId/tasks). Some operations may be restricted by the API plan or scope, so verify your token scopes.\nIf a write endpoint is unavailable, consult your admin to adjust permissions or use alternatives like creating notes or tags to achieve similar outcomes.
The API uses JSON for requests and responses. Send Content-Type: application/json and Accept: application/json headers, and structure payloads in JSON.\nIf you need CSV or other formats, implement a transformation layer in your app to convert the JSON data to your preferred format.
Common errors include invalid credentials, insufficient scope, and rate limit exceedance. Use the Retry-After header and exponential backoff when retrying failed requests. Monitor quota usage and implement caching where appropriate to reduce calls.
Yes. You can attach notes and tags to contacts via the API. Use POST /contacts/:contactId/notes to add notes and POST /contacts/:contactId/tags to apply tags for segmentation and richer context.\nCombine notes, tags, and tasks to build a complete activity trail for each contact.
Due to high volume, we will be upgrading our server soon!
