Frequently Asked Questions

What authentication methods are supported

The Contacts API supports token based authentication. Use your API token with secure storage and include the appropriate scope. For Checkfront, enable read and write access as needed. If you use OAuth, follow the standard exchange flow to obtain short lived tokens and refresh tokens. Always protect your credentials and rotate them periodically.

Start with the core endpoints such as GET /contacts/:contactId and POST /contacts/. These allow you to read and create contacts. Then extend to tasks, notes, and appointments as your workflow requires. Use proper field mapping to ensure data integrity.

Yes. Real time or near real time sync is possible depending on your webhook or polling configuration and API rate limits. Implement error handling and retries for reliability.

You can often set up most integrations without coding using the GHL interface and the Composer. Some complex mappings may require light scripting, but the platform supports no code options.

Map the fields in a one to one or many to one style depending on data. Create a field mapping document and test with sample records to ensure accuracy between systems.

Rate limits depend on your plan. Expect throttling if you exceed requests per minute. Implement exponential backoff and retries to maintain stability.

If a sync fails, check logs for the failing endpoint, verify credentials, and re-run the sync. Consider using retries and alerting to catch future failures.
